Paleontologists Describe Ten New Species of Trilobites

Trilobites are extinct arthropods that dominated the faunas of the oceans of the Paleozoic era. During their time on Earth, which lasted much longer than the dinosaurs, between 521 and 252 million years ago, they survived two major episodes of mass extinctions and dominated ocean floor ecosystems. There are more than 20,000 known trilobite species.

In a 100-page monograph published in the journal Papers in Palaeontology, paleontologists have described ten new species of trilobites from the tuff-bearing Cambrian-Ordovician layers of Ko Tarutao island, Satun province, southernmost peninsular Thailand. Trilobites are extinct arthropods that dominated the faunas of the oceans of the Paleozoic era. During their time on Earth, which lasted much longer than the dinosaurs, between 521 and 252 million...

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.
