What is the Carboniferous period known for?
The Carboniferous Period. The Carboniferous Period is famous for its vast swamp forests, such as the one depicted here. Such swamps produced the coal from which the term Carboniferous, or "carbon-bearing," is derived. The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era.
What was the average height of the Earth during the Carboniferous?
Falling from 120 m to present-day level throughout the Mississippian, then rising steadily to about 80 m at end of period. The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period 358.9 million years ago (Mya), to the beginning of the Permian Period, 298.9 Mya.
How big were insects in the Carboniferous period?
Insects reached their largest sizes during the Carboniferous Period (359-299 million years ago), with some flying species growing as large as a present-day hawk and one type of flightless arthropod growing even larger than an average-sized adult human!
Who named the Carboniferous system?
The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian.

Was there a Carboniferous Period before dinosaurs?
By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period. (It was the archosaurs that went on to spawn the first dinosaurs nearly a hundred million years later.)
Could humans survive in the Carboniferous period?
The earliest period in which humans could live as a land-based rather than a coastal species would be the Devonian (419-358 MYA) or the Carboniferous (358-298 MYA) eras, during which land-based life spread out and became established.
What evolved during the Carboniferous period?
During the Carboniferous, more and more species of tetrapods evolved. Some were early amphibians that began their lives in the water and later moved onto land. Some were early reptiles that developed leathery skin as they moved to the parts of land that were very dry.
When did oxygen levels start declining?
However, previous carbon-cycle modeling by Robert Berner at Yale University has calculated that atmospheric oxygen began plummeting soon after, reaching about 16 percent at the end of the Permian and bottoming out at less than 12 percent about 10 million years into the Triassic period.
What animals went extinct in the Carboniferous period?
Some benthic organisms that were common to early and middle Paleozoic times began to decline during the Carboniferous. These included the trilobites (which became extinct at the end of the Permian), rugose corals, and sponges. The pelagic, or water column, environment was inhabited by a profusion of cephalopods.
What was the Earth like during the Carboniferous period?
Early in the Carboniferous Period, Earth's climate was warm. Later, glaciers formed at the poles, while equatorial regions were often warm and humid. Earth's climate became similar to today's, shifting between glacial and interglacial periods.
Who ruled the Earth before dinosaurs?
For approximately 120 million years—from the Carboniferous to the middle Triassic periods—terrestrial life was dominated by the pelycosaurs, archosaurs, and therapsids (the so-called "mammal-like reptiles") that preceded the dinosaurs.
What was the first era of Earth?
Precambrian TimePrecambrian Time: 4.6 billion to 542 Million Years Ago Precambrian Time started at the beginning of the Earth 4.6 billion years ago. For billions of years, there was no life on the planet. It wasn't until the end of Precambrian Time that single-celled organisms came into existence.

How do you say Carboniferous period?
Here are 4 tips that should help you perfect your pronunciation of 'carboniferous': Break 'carboniferous' down into sounds: [KAA] + [BUH] + [NIF] + [UH] + [RUHS] - say it out loud and exaggerate the sounds until you can consistently produce them.
How long ago was the Carboniferous era?
This time period took place 359 to 299 million years ago. The Carboniferous period, part of the late Paleozoic era, takes its name from large underground coal deposits that date to it. Formed from prehistoric vegetation, the majority of these deposits are found in parts of Europe, North America, and Asia that were lush, ...
How many years ago was the Carboniferous?
In the U.S., scientists divide the Carboniferous into two parts: the earlier Mississipian (359.2 million to 318.1 million years ago) and the later Pennsylvanian (318.1 million to 299 million years ago).
What is the carboniferous swamp?
Carboniferous Swamp. Characteristic of the Carboniferous period (from about 360 million to 300 million years ago) were its dense and swampy forests, which gave rise to large deposits of peat. Over the eons the peat transformed into rich coal stores in Western Europe and North America. The name "Carboniferous" refers to this coal.

What was the name of the supercontinent that the Earth's landmasses were moving toward?
By the end of the Carboniferous, the Earth's landmasses were moving toward a single, global supercontinent called Pangaea.
How was carboniferous coal made?
Carboniferous coal was produced by bark-bearing trees that grew in vast lowland swamp forests. Vegetation included giant club mosses, tree ferns, great horsetails, and towering trees with strap-shaped leaves. Over millions of years, the organic deposits of this plant debris formed the world's first extensive coal deposits—coal that humans are still burning today.
What is the effect of the growth of forests on the atmosphere?
The growth of these forests removed huge amounts of carbon dioxide from the atmosphere, leading to a surplus of oxygen. Atmospheric oxygen levels peaked around 35 percent, compared with 21 percent today. It also may explain the giant creepy-crawlies that now emerged—the size reached by insects and similar creatures is thought to be limited by the amount of air they are able to breathe.
How many years ago was the Carboniferous Period?

In Europe, the Carboniferous Period is subdivided into the Dinantian and succeeding Silesian subsystems, but the boundary between those divisions is below the internationally accepted Mississippian-Pennsylvanian boundary.
Why did the Gondwana glaciers not occur in the Northern Hemisphere?
Coeval (parallel) continental glaciations did not occur in the high latitudes of the Northern Hemisphere, probably because the landmasses were too small to sustain large ice fields.
How did paleogeography influence climate?
Continental glaciation expanded in Gondwana, allowing glaciers to extend into lower latitudes that otherwise might have formed coal swamps. As mountains developed toward the close of the Pennsylvanian, rain-shadow effects became more influential, inhibiting the process of coal deposition in the basins of western Europe. Flora of the Carboniferous followed the same climatic gradients as glacial deposits. Fossil plants found in areas located in high latitudes during the Carboniferous exhibit seasonal growth rings, while those of the presumed equatorial coal swamps lack such rings, as do modern tropical trees.
What was the distribution of land and sea during the Carboniferous?
Upland areas of the continental interiors underwent substantial erosion during the Carboniferous. Shallow seas occupied the continental shelf margins surrounding the continents. Fringe areas of Carboniferous continents may very well have become the continental interiors of the present day. Deeper troughs ( geosynclines) lay seaward of the continental masses, and their sedimentary record is now characterized by mountains.
What is the longest period of the Paleozoic era?
Its duration of approximately 60 million years makes it the longest period of the Paleozoic Era and the second longest period of the Phanerozoic Eon. The rocks that were formed or deposited during the period constitute the Carboniferous System. The name Carboniferous refers to coal -bearing strata that characterize the upper portion ...

What was the name of the mountain belt that was formed by the late Carboniferous collision of Laurasia?
Geologically, the Late Carboniferous collision of Laurasia (present-day Europe, Asia, and North America) into Gondwana (present-day Africa, South America, Antarctica, Australia, and India) produced the Appalachian Mountain belt of eastern North America and the Hercynian Mountains in the United Kingdom. A further collision of Siberia and eastern ...
What fossils were found in the Carboniferous?
The earliest amniote fossil was the lizard-like Hylonomus, which was lightly built with deep, strong jaws and slender limbs. The basal tetrapods became more diverse during the Carboniferous. Predators with long snouts, short sprawling limbs and flattened heads such as temnospondyls, like Amphibiamus (above) appeared.
What are the innovations of the Carboniferous?
Biologically, we see one of the greatest evolutionary innovations of the Carboniferous: the amniote egg, which allowed for the further exploitation of the land by certain tetrapods. It gave the ancestors of birds, mammals, and reptiles the ability to lay their eggs on land without fear of desiccation. Geologically, the Late Carboniferous collision ...
Which group of amphibians grew to the size of crocodiles in the Permian?
On the left is Amphibiamus lyelli, an early temnospondyl. These amphibian-like early tetrapods grew to the size of crocodiles in the Permian and Triassic.

Though many spectacular plant forms dominated the Carboniferous, most of them disappeared before the end of the Paleozoic. On the left, Neuropteris, a leaf form associated with the cycad-like seed-ferns. On the right, terminal branches from Lepidodendron sternbergii, one of the great scale trees, most of which went extinct in the late Middle Pennsylvanian.
What is the Carboniferous Period?
The Carboniferous Period is a geologic time period that took place between 360 to 286 million years ago. The Carboniferous Period is named after the rich coal deposits that are present in rock layers from this time period.
What was the effect of the Carboniferous Period on the Earth?
During the Carboniferous Period, the vast oceans that covered the earth often flooded the continents, creating warm, shallow seas. It was during this time that the armored fish that had been abundant in the Devonian Period became extinct and were replaced by more modern fishes.
How big were tetrapods in the Carboniferous Period?
By the middle the Carboniferous Period, tetrapods were common and quite diverse. The varied in size (some measuring up to 20 feet in length). As the climate grew cooler and drier, the evolution of amphibians slowed and the appearance of amniotes lead to a new evolutionary path. Cite this Article.
What happened to the marine ecosystem during the Carboniferous Period?
As the Carboniferous Period progressed, the uplifting of landmasses resulted in an increase in erosion and the building of floodplains and river deltas. The increased freshwater habitat meant that some marine organisms such as corals and crinoids died out.
What is the name of the period after the rich coal deposits that are present in rock layers from this time period?
The Carboniferous Period is named after the rich coal deposits that are present in rock layers from this time period.
Which tetrapods evolved during the Carboniferous Period?
These included the temnospondyls and the anthracosaurs. Finally, the first diapsids and synapsids evolved during the Carboniferous.
Which geologic period is preceded by the Devonian period?
It is the fifth of six geologic periods that together make up the Paleozoic Era. The Carboniferous Period is preceded by the Devonian Period and followed by the Permian Period.
How long ago was the Carboniferous Period?
The Carboniferous Period ran from about 360 million years ago to about 300 million years ago . It is a period on the prehistoric timeline that is under appreciated but is one that has affected humanity greatly especially during the Industrial Revolution. That’s because this period was given its name because of the deposits of coal that existed throughout Asia, Northern Europe, and parts of North America. While the term “carboniferous” is used to describe the period throughout the world, in the U.S it has been separated into the Mississippian Epoch and the Pennsylvanian Epoch. The Mississippian is used to describe the early part of this period and Pennsylvanian is used to describe the later part of this period.
What were the cockroaches in the Carboniferous Period?
Life in the oceans during the Carboniferous Period consisted mainly of various corals (tabulate and rugose), Foraminifera, brachiopods, Ostracoda, echinoderms, and microconchids. These weren’t the only types of marine life, however. There were also sponges, Valvulina, Endothyra, ...
What caused the carboniferous rainforest to collapse?
This cooling of the atmosphere, coupled with it beginning to dry out, probably led to the Carboniferous Rainforest Collapse. This climate change event fragmented the rainforest of the world and then eventually destroyed most of them.
How long did the Carboniferous Period last?
The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era. The term “Carboniferous” comes from England, in reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America.
What is the climate of the Carboniferous?
The beginning of the Carboniferous generally had a more uniform, tropical, and humid climate than exists today. Seasons if any were indistinct. These observations are based on comparisons between fossil and modern-day plant morphology. The Carboniferous plants resemble those that live in tropical and mildly temperate areas today. Many of them lack growth rings, which suggests a uniform climate. This uniformity in climate may have been the result of the large expanse of ocean that covered the entire surface of the globe, except for a localized section where Pangea, the massive supercontinent that existed during the late Paleozoic and early Triassic, was coming together.
What fossils were found in the Pennsylvanian subsystem?
Index fossils used for the Pennsylvanian Subsystem are fusulinid foraminifers and the pollen and spores from the coal forests prevalent during that time. The Mississippian-Pennsylvanian boundary is marked by the appearance of the fusulinid Pseudostaffella antiqua. Other fossils used to identify the early Pennsylvanian are the three ammonoid cephalopod genera Gastrioceras, Daiboloceras, and Paralegoceras, all found in marine deposits.
What are the two main groups of the Carboniferous?
The Mississippian and Pennsylvanian, in turn, are subdivided into a number of internationally recognized stages based on evolutionary successions of fossil groups . These stages are (from early to late) Tournaisian, Visean, and Serpukhovian for the Mississippian — and Bashkirian, Moscovian, Kasimovian, and Gzhelian for the Pennsylvanian.
What were the major changes during the Carboniferous?
In addition to having the ideal conditions for the formation of coal, several major biological, geological, and climatic events occurred during this time. Biologically, we see one of the greatest evolutionary innovations of the Carboniferous: the amniote egg, which allowed for the further exploitation of the land by certain tetrapods. It gave the ancestors of birds, mammals, and reptiles the ability to lay their eggs on land without fear of desiccation. Geologically, the Late Carboniferous collision of Laurasia (present-day Europe, Asia, and North America) into Gondwana (present-day Africa, South America, Antarctica, Australia, and India) produced the Appalachian Mountain belt of eastern North America and the Hercynian Mountains in the United Kingdom. A further collision of Siberia and eastern Europe created the Ural Mountains of Russia. And climatically, there was a trend towards mild temperatures during the Carboniferous, as evidenced by the decrease in lycopods and large insects, and an increase in the number of tree ferns.
What are index fossils?
Index fossils are the remains of plants and animals that characterize a well-defined time span and occur over a wide range of geography. Fossils of marine life characterize the Mississippian, as shallow epicontinental seas covered the United States at that time. These fossils include solitary corals and Syringopora, tubular colonial corals. Other fossil colonial corals include Stelechophyllum and Siphonodendron. Because conodont fossils are distributed all over the world, they are utilized internationally to date Mississippian rocks.
What are the two periods of carboniferous?
In the United States the Carboniferous is usually broken into Mississippian (earlier) and Pennsylvanian (later) Period s. The Mississippian is about twice as long as the Pennsylvanian, but due to the large thickness of coal bearing deposits with Pennsylvanian ages in Europe and North America, the two subperiods were long thought to have been more or less equal. The faunal stages from youngest to oldest, together with some of their subdivisions, are:
What was the name of the event that occurred before the end of the Carboniferous Period?
Before the end of the Carboniferous Period, an extinction event occurred. On land this event is referred to as the Carboniferous Rainforest Collapse (CRC). Vast tropical rainforests collapsed suddenly as the climate changed from hot and humid to cool and arid.
How much lignin is in carboniferous bark?
This compares to modern values less than 1 to 4. This bark, which must have been used as support as well as protection, probably had 38% to 58% lignin.
Why did the Carboniferous have coal?
The first of these is the appearance of bark-bearing trees (and in particular the evolution of the bark fiber lignin). The second is the lower sea levels that occurred during the Carboniferous as compared to the Devonian period. This allowed for the development of extensive lowland swamps and forests in North America and Europe. Based on a genetic analysis of mushroom fungi, David Hibbett and colleagues proposed that large quantities of wood were buried during this period because animals and decomposing bacteria had not yet evolved that could effectively digest the tough lignin. It is assumed that fungi that could break it down did not arise before the end of the period, making future coal formation much more rare. The Carboniferous trees made extensive use of lignin. They had bark to wood ratios of 8 to 1, and even as high as 20 to 1. This compares to modern values less than 1 to 4. This bark, which must have been used as support as well as protection, probably had 38% to 58% lignin. Lignin is insoluble, too large to pass through cell walls, too heterogeneous for specific enzymes, and toxic, so that few organisms other than Basidiomycetes fungi can degrade it. It can not be oxidized in an atmosphere of less than 5% oxygen. It can linger in soil for thousands of years and inhibits decay of other substances. Probably the reason for its high percentages is protection from insect herbivory in a world containing very effective insect herbivores, but nothing remotely as effective as modern insectivores and probably many fewer poisons than currently. In any case coal measures could easily have made thick deposits on well drained soils as well as swamps. The extensive burial of biologically produced carbon led to a buildup of surplus oxygen in the atmosphere; estimates place the peak oxygen content as high as 35%, compared to 21% today. This oxygen level probably increased wildfire activity, as well as resulted in insect and amphibian gigantism—creatures whose size is constrained by respiratory systems that are limited in their ability to diffuse oxygen.
What were the main terrestrial organisms in the Carboniferous period?
Terrestrial life was well established by the Carboniferous period. Amphibians were the dominant land vertebrates, of which one branch would eventually evolve into reptiles, the first fully terrestrial vertebrates. Arthropods were also very common, and many (such as Meganeura), were much larger than those of today. Vast swaths of forest covered the land, which would eventually be laid down and become the coal beds characteristic of the Carboniferous system. A minor marine and terrestrial extinction event occurred in the middle of the period, caused by a change in climate. The later half of the period experienced glaciations, low sea level, and mountain building as the continents collided to form Pangaea.
Where is Aviculopecten subcardiformis from?

Which glacial period was mostly warm?
The early part of the Carboniferous was mostly warm; in the later part of the Carboniferous, the climate cooled. Glaciations in Gondwana, triggered by Gondwana’s southward movement, continued into the Permian and because of the lack of clear markers and breaks, the deposits of this glacial period are often referred to as Permo-Carboniferous in age.
What was the environment like during the early era of the 'Arthropods'?
The air was hot and humid during this period, and vast swampy rainforests covered the land, making it the perfect environment for these animals. They were able to diversify greatly, competing with amphibians that were forming their own distinct groups. Despite the strong presence of amphibians at this time, arthropods were able to colonize the land in many successful forms, from cat-sized scorpions to large proto-cockroaches.
Why did the griffinflies die?
Many scientists believe these giant arthropods died out because of a decrease in atmospheric oxygen from the rainforest collapse. There was no longer a sufficient amount of oxygen to power their large bodies, so they began to shrink in size. One problem with the oxygen theory is that a giant griffinfly named Meganeuropsis permiana thrived during the Permian Period (299-252 million years ago) when oxygen levels were lower. This insect was almost as large as its close relative Meganeura monyi, possessing a wingspan of 69 centimeters (over 2 feet). However, griffinflies such as Meganeuropsis permiana and Meganeura monyi had very thin, light-weight bodies that may not have required as much oxygen as other large arthropods. This could explain why giant griffinflies were able to survive into the next period while the rest of the arthropods shrank.
Where was Pulmonoscorpius Kirktonensis found?
Its fossils have been discovered at the East Kirkton Quarry in Scotland and its body design was similar to that of a present-day scorpion.
How long has Lisa studied natural history?
Lisa has studied natural history for over 15 years and is a fossil collector as well. She loves sharing her knowledge with others.
When did insects reach their largest size?
Insects reached their largest sizes during the Carboniferous Period (359-299 million years ago), with some flying species growing as large as a present-day hawk and one type of flightless arthropod growing even larger than an average-sized adult human!
Why did ancient larvae grow large?
These ancient larvae may have grown large to avoid oxygen poisoning, as larger larvae would absorb lower amounts of oxygen relative to their body sizes. 3. Lack of predators.
