I'd say say start at the agreed beginning, the Triassic period, but know there were still some assholes clawing their way out of the water before then.
My dad subscribed me to these national geographic style magazines when I was 6. Everytime i went to the library it was redwall books and dinosaurs. I couldn't tell you now how to get started.
Just start digging! Trust me, the pieces will fall together the more you explore.
