Cenozoic Era
All of them. No humans predate the Cenozoic. In fact, I'm fairly certain no primates predate the Cenozoic. The Cenozoic era is today's era, and extends back 65 million years ago, long before our species or even our ancestral species came into existence.

the cenozoic era
After Palezoic era (251-542 Million years ago), came Mesozoic era (65.5-251 Million years ago). The Mesozoic era is subdivided into 3: Triassic Period (199.6-251 mya) Jurassic Period (145.5-199.6 mya) Cretaceous Period (65.5-145.5 mya) Note: mya means million years ago.
The Cenozoic Era has the greatest variety and quantity of mammalian life.

The Paleozoic era was from 540 million years ago to about 245 million years ago. After that came the Mesozoic era, and that lasted from the end of the Paleozoic to 65 million years ago, when the earth entered the Cenozoic era.
The Cenozoic era started 65 million years ago.
