Here are some keywords to get your googling started: Cambrian Period – Geologists cut the past up into segments. The Cambrian is a geologic "period" that lasted from 570-505 million years ago. Ordovician Period – The geologic period that followed the Cambrian and lasted from 505 million years ago to about 440 million years ago. Cambrian Explosion of Life – The evolutionary event (during the Cambrian period) in which the first marine animals diversified into all kinds of different forms. All of the basic body plans – like segmented/non-segmented, asymmetric/symmetric, radial/bilateral – emerged during this time. Great Ordovocian Biodiversification Event (GOBE) – Another big evolutionary event that happened about 40 million years after the Cambrian explosion. Often described as a "filling out" of the taxonomic tree, whose main branches sprouted during the Cambrian. Late-Ordovician Extinction – The major mass extinction event at the end of the Ordovician period. Considered by most paleontologists to be one of the 5 biggest mass extinctions since animals first evolved on Earth. Hirnantian Extinc
