What was happening on Earth during the Paleozoic Era?
Paleozoic Era, also spelled Palaeozoic, major interval of geologic time that began 541 million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about 252 million years ago with the end-Permian extinction, the greatest extinction event in Earth history.
What was the average climate in the Paleozoic Era?
During this time, average global temperatures were exceedingly high; the early Carboniferous averaged at about 20 degrees Celsius (but cooled to 10 °C during the Middle Carboniferous).
What was the environment like in Michigan during the Paleozoic period?
During the early part of the Paleozoic Michigan was covered by a shallow tropical sea which was home to a rich invertebrate fauna including brachiopods, corals, crinoids, and trilobites. Primitive armored fishes and sharks were also present. Swamps covered the state during the Carboniferous.
Was Michigan once an ocean?
In the Paleozoic Era, roughly 400 million years ago, Michigan wasn’t the chilly northern state we know it as now. It was somewhere near the equator and it was covered in a shallow, tropical sea, complete with ancient marine life.
Why are there no dinosaur bones in Michigan?
First, the bad news: No dinosaurs have ever been discovered in Michigan, mainly because during the Mesozoic Era, when the dinosaurs lived, the sediments in this state were steadily being eroded by natural forces.
How long ago did the Paleozoic era end?
541 (+/- 0.4) million years ago – 251.902 (+/- 0.024) million years ago

What was the climate like during the Paleozoic era?
The Paleozoic era was a geological era with six distinct periods. It lasted 289 million years ago before ending in the end Permian mass extinction event. The climate during the Paleozoic era varied from period to period. During the Cambrian the climate is presumed to have been moderate. It warmed until… See full answer below.
How did the Permian period end the Paleozoic era?
The Permian Geological Period ended – along with the Paleozoic Era – by a mass extinction event that erased 96% of marine species and 70% of terrestrial land species. This is known as the Permian-Triassic extinction event and it took 30 million years for natural life to recover from this disastrous extinction.
How did tectonic plate movements affect the Paleozoic era?
By the end of the Paleozoic, continued tectonic plate movements had forced these cratons together to form the supercontinent of Pangea. Large areas of all continents were episodically inundated by shallow seas, with the greatest inundations occurring during the Ordovician and early Carboniferous ( Mississippian) periods.
Where was the limestone found in the Paleozoic era?
The causes of both these events are still not fully understood and the subject of much research and controversy. Roughly halfway in between, animals, fungi, and plants colonized the land, the insects took to the air, and the limestone shown in the photo at right was deposited near Burlington, Missouri.
