All of them from Paleozoic, Mesozoic & Cenozoic era.

NOOOO why is Pisco loosing

I’ll change to pisco just cause i don't want morrison to win

Not that i hate the morrison or something but it’s already been covered so many times, i’d rather learn something new

I'll change my vote to Pisco, as long as an aquatic formation wins I'll be happy

I’m not even that interested in prehistoric aquatic life but i just want something other than hell creek or the morrison to have the spotlight when they’ve already been covered thousands of times

I’ll do all these eventually, but seals, sloths, sharks, whales, penguins, pseudo toothed birds, sharks, gharials, and more existing in one ecosystem is a writing opportunity too great to ignore

All of the above

All these I will do a series on, this poll is asking which on gets a series first
