The Quaternary Period and Cenozoic Era continue today and likely will remain until the next mass extinction event. Humans remain dominant and new species are discovered daily.
What are the three Mesozoic Era?
The Mesozoic is divided into three time periods: the Triassic (245-208 Million Years Ago), the Jurassic (208-146 Million Years Ago), and the Cretaceous (146-65 Million Years Ago).

Horsetails grew near bodies of water. Rainfall increased and the oceans rose during the Jurassic Period (208-145 million years ago).
