It existed during the Maastrichtian age of the late Cretaceous period, between about 70 and 66 million years ago, in western Europe and North America.

A 520 million-year-old fossilised nervous system – so well-preserved that individually fossilised nerves are visible – is the most complete and best example yet found, and could help unravel how the nervous system evolved in early animals - Complete specimen of Chengjiangocaris kunmingensis from the early Cambrian Xiaoshiba biota of South China
Female skull from 300BC, found in a megalithic chamber tomb in Roque d'Aille in the Var. Exposed to a pyre. The skull had been trepanned -- carved open with flint and operated on for 3 hours. The artificial ear is made of seashell (spondylus Graederopus). Signs of wear (likely from the woman playing with her ear) show that the woman lived for many years after the open brain operation.
