Trilobite fossil

Trilobites are arthropods in the class Trilobida of the phylum Arthropoda. The body is divided into three parts: head, chest, and abdomen; There is a shell on the back, which is vertically divided into three pieces. The head is covered with a hard shell, which is called a head armor; The central raised part of the head armor is called the saddle, and the shape and size of the saddle vary greatly depending on the type; The front of the saddle is the skull, which is covered by eyes; The abdomen and tail are also wrapped in shells. Named after the vertical division of the carapace on the back into three pieces. Widely distributed in ancient oceans, fossils are found on various continents today. I like to live in warm shallow waters and feed on algae, protozoa, and other animals.
