Trilobites are animals that existed millions of years ago. Geologists, anthropologists, and paleontologists study the fossilized remains of this animal.
So that we can learn more about ancient earth.
Trilobites: The Index Fossil There are many thousands of known species of trilobite fossils found worldwide. Trilobites are considered to be good index fossils because they evolved so rapidly, and this allows geologists the ability to date the rocks in which the trilobites are found. The discovery of trilobites is second only to the discovery of dinosaurs, and new species of trilobites are still being discovered today.
The Trilobites was created in 1984.
Trilobites did not have jaws, therefore they could not bite.
Trilobites first appeared in the Cambrian Period around 521 million years ago, while fish began to emerge around 480 million years ago. This evolutionary timeline suggests that trilobites appeared earlier than fish in Earth's geological history.
Trilobites are extinct but they were marine animals.
Vampires exist only in stories, films, and folklore.
Scientists believe that trilobites reproduced sexually. These prehistoric and extinct creatures were a type of arthropod that probably laid eggs. Trilobites lived about 250 million years ago.
