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.

Insects thrived in the late Paleozoic Era.

Three types of marine animals in the Paleozoic Era were trilobites, brachiopods, and archaeocyathids.
They were jawless fish that lived during the Paleozoic era Stunningly some of our oldest ancestors came from ostracoderms!
paleozoic
Yes. If no animals survived from the Paleozoic into the mesozoic, then there would be no animals today.
The main characteristic that distinguishes the fossil record of the Paleozoic Era from the Precambrian Era is the appearance of diverse and complex multicellular organisms in the Paleozoic Era. In the Precambrian Era, the fossil record primarily consists of simpler single-celled organisms. Additionally, the Cambrian Explosion, which occurred at the beginning of the Paleozoic Era, marked a significant increase in the diversity of life forms.
The first period in the Paleozoic Era was the Cambrian.
Land based animals first became common in the Paleozoic Era. It is the earliest era of the 3 in the Phanerozoic Eon.
The Eras go like this: Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era Dinosaurs lived during the Mesozoic Era, and we live in the Cenozoic Era. Paleozoic means "ancient life" Mesozoic means "middle life" Cenozoic means "recent life" All eras end in a huge disaster
The Paleozoic Era
No, dinosaurs first appeared in the Mesozoic era, specifically during the Triassic period. The Paleozoic era preceded the Mesozoic era and was home to a different group of animals, including early fish, amphibians, and reptiles.
Many of the animals began to die off and became extinct.
Fish are animals that have been around for millions of years and are currently part of the modern era, known as the Cenozoic era. They have evolved and adapted over time to inhabit a wide variety of aquatic environments around the world.
