Review Of The Fossils #1

The statement that all dinosaurs lived at the same time is false. Dinosaurs existed over a span of millions of years, from the Triassic period to the Cretaceous period. They did not all coexist at the same time. Different species of dinosaurs lived during different time periods, and some even became extinct before others appeared.

With great forests and swamps this picture represents the carboniferous period. The triassic didn't have the lush forests and the devonian didn't have forests yet!

The time period called the "Age of Crinoids" is the Silurian period. Crinoids were abundant during this period and flourished in the oceans. They are marine animals that resemble flowers and are commonly known as sea lilies or feather stars. The Silurian period occurred approximately 443 to 419 million years ago and is characterized by a diverse range of marine life.

The Permian period ended with the world's largest mass extinction. This extinction event, known as the Permian-Triassic extinction event, occurred approximately 252 million years ago and resulted in the loss of about 96% of marine species and 70% of terrestrial species. It is considered the most severe mass extinction event in Earth's history, wiping out a significant portion of life on the planet. The Permian period is therefore associated with this catastrophic event, making it the correct answer.

This sea creature is called Dunkleosteus...who live during the great devonian period!
