Not Extinct Through out the Cenozoic era, the oceans were home to nearly the same invertebrate animals as today. Foraminifera were common as well. Sponges, coral, starfish, seaurchens, and sand dollars were common as well Brachiopods and cephalopods were rare. Mollusksclams, oysters, mussels, and snails- thrived through out the era. Crabs and barnacles were common as well. A land, the Spiders, centipedes, scorpions, and insects continued to thrive. Insects including butterflies, moths, bees, wasps, ants, beetles, and many others. Most Cenozoic fish were like that of late Mesozoic time. Sharks and rays were abundant and gigantic. Some sharks were 20 meters long with jaws nearly 2 meters wide. Amphibians, such as frogs, toads, and salamanders, were about as common as they are now. The reptiles-turtles, lizards, snake, and crocodiles- resemble those of today. Birds developed that were similar to those of today. At times, there were many large, flightless, ostrich like types. Some were three meters tall. Extinct Creodonts, oreodons an early grazing animal that resembles a deer, the mastodon a kind of gigantic elephant, brontotherium a gigantic rhino like animal, blachitherium rhino like animal , armadillo a gigantic sloth like animal. These are just some of the animals that lived in the Cenozoic era that are now extinct.
In the earlier part of the Cenozoic, the world was dominated by the gastornid birds, terrestrial crocodiles like Pristichampsus, and a handful of primitive large mammal groups like uintatheres, mesonychids, and pantodonts. But as the forests began to recede and the climate began to cool, other mammals took over. The Cenozoic is full of mammals both strange and familiar, including chalicotheres, creodonts, whales, primates, entelodonts, saber-toothed cats, mastodons and mammoths, three-toed horses, giant rhinoceros like Indricotherium, and brontotheres.
creatures that lived in the paleozoic era are dunkleosteus the bone headed fish
another is diplocaulus also TRILOBITE another is dimetrodon also EURYPTERIDS
Humans appeared in the Cenozoic Era.... :D
The Neozoic era is the era after the dinosaurs became extinct. Animals included in this era are giant sloths, mammoths, mastodons, saber-tooth tigers, camels and horses.

They lived in the ocean because they were marine animals.
Three types of marine animals in the Paleozoic Era were trilobites, brachiopods, and archaeocyathids.
Yes. If no animals survived from the Paleozoic into the mesozoic, then there would be no animals today.
They were jawless fish that lived during the Paleozoic era Stunningly some of our oldest ancestors came from ostracoderms!
It's not much of the organisms that dominated the paleozoic era, it's the species of animals. Alot of the larger reptiles and early ancestors of dinosaurs conquered and dominated the paleozoic era.
In the beginning of the Paleozoic Era, animals began to develop hard parts like shells and bones.

Warm, shallow seas covered most of Earth's surface near the end of the Paleozoic Era.
