Ordovician animals

Well, I am back! Anywho, for today's topic, I shall be discussing David Peters, apparently a rather infamous figure in the paleontology worl...

The Ordovician /ɔrdəˈvɪʃən/ is a geologic period and system, the second of six of the Paleozoic Era, and covers the time between 485.4 ± 1.9 to 443

Arandaspis was a genus of Ordovician jawless fish, the first known vertebrates.

Art illustration - Aquatic Animals - Ammonoidea: commonly known as ammonites, are a subclass of extinct mollusc cephalopods that existed in the seas from the Ordovician (about 340 million years ago) until the end of the Cretaceous (66 million years ago). Thanks to its rapid development and worldwide distribution are excellent index fossils for dating rocks and have enabled the development of succession of biostratigraphic biozones great precision.
