Trilobites were the most numerous arthropods

The word “trilobite” means “three parts”. It was given to creatures such as Conocoryphe because the body is always divided into three parts, a head, a body and a tail. Trilobites first lived about 550 million years ago and by 500 million years ago were among the most numerous animals.
