Extinct Animal Description

Trilobite


A trilobite is an extinct marine invertebrate that is said to have lived 250 million - 600 million years ago.  Several thousand species of trilobite have been discovered by their fossil remains. These insects were 1/4 of an inch (6mm). These insects became extinct by super-vulcanism - lots of volcanoes spewing lava into the atmosphere killing most forms of life.
