A pictorial guide to the orders of trilobites / Иллюстрированный путеводитель по отрядам трилобитов

They went extinct before dinosaurs even existed, and are the signature creatures of the Paleozoic Era, the first era to generate a diversity of complex life forms, including nearly all of the phyla of today. Although dinosaurs are the most well-known fossil life forms, trilobites are also a favorite among those familiar with paleontology (the study of the development of life on Earth) <...>
