Many scientists maintain that chordates originated sometime earlier than 590 million years ago; that is, they predate the fossil record.Such early representatives were soft-bodied and therefore left a poor fossil record. The oldest known fossil chordate is Pikaia gracilens, a primitive cephalochordate dated to approximately 505 million years ago.Study with Quizlet and memorize flashcards containing terms like humans appear, largest mass extinction in history, volcanic eruptions and more.The Cambrian Period ( / ˈkæmbri.ən, ˈkeɪm -/ KAM-bree-ən, KAYM-; sometimes symbolized Ꞓ) is the first geological period of the Paleozoic Era, and of the Phanerozoic Eon.
