Vertebrates: Fossil Record. Because bone is resistant to decay, the fossil record of vertebrates is extensive and has been studied for over 200 years. We can't present all of it on one page; visit our exhibits on specific vertebrate groups for more detailed information. But to give a very brief summary: The first known vertebrate fossils, found at the Chengjiang locality in China, date back to the early Cambrian. These early vertebrates, such as Haikouichthys, are small, tapered, streamlined animals showing eyes, a brain, pharyngeal arches, a notochord, and rudimentary vertebrae. Vertebrates appear to have radiated in the late Ordovician, about 450 million years ago.
