Why did the Paleozoic era end?
The Paleozoic ended with the largest extinction event in Earth’s history, Permian-Triassic extinction eventThe effects of this catastrophe were so devastating that it took 30 million years for life on land to recover to the Mesozoic. The recovery of life in the ocean may be much faster.
Did any Paleozoic animals survive?
By the end of the Paleozoic, evolution had led to the existence of complex terrestrial and marine animals. … However, the event that marked the end of the Paleozoic was the mass extinction that wiped out nearly 96 percent of marine life and 70 percent of land animals.

Pangaea existed for 100 million years, during which time several animals flourished, including Sagittarius, a family of herbivores that includes the ancestors of mammals. During the Permian period, insects such as beetles and dragonflies flourished.
What comes after the dinosaurs?
good old days.about 60 million years ago, after Ocean Dinosaurs Extinct, the ocean is a safer place. Marine reptiles are no longer dominant, so there is plenty of food around, and birds like penguins have room to evolve and grow. Eventually, the penguins became tall, waddling predators.
What was life in the Permian era?
Two important groups of animals dominated the Permian landscape: Synaptoids and Lizards. Synapsids have a single temporal opening in their skulls and are thought to eventually lead to the mammalian lineage. Sauropsids have two skull openings and are the ancestors of reptiles, including dinosaurs and birds.
