What is a trilobte?

Answer 1

Trilobites (pronounced Wikipedia:IPA_for_English, meaning "three lobes") are a well-known fossil group of Extinctionmarine Arthropodthat form the Class_(biology) Trilobita. The first appearance of trilobites in the fossil record defines the base of the Atdabanianstage of the Early_Cambrianperiod (), and they flourished throughout the lower Paleozoicera before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders, with the sole exception of Proetida, died out. Trilobites finally disappeared in the Permian-Triassic_extinction_eventat the end of the Permianabout .

Answer 2

A trilobite is an extinct marine arthropod that lived from the Early Cambrian to the end of the Permian period. They had a hard exoskeleton divided into three lobes, giving them their name. Trilobites are important for Paleontology as they are among the earliest known complex organisms.
