Not a fan of Fraction or bagley but i gave it a try anyway. The art kind of sucked and the story was pretty bland.
This kind of thing happens in comics all the time but 2.6 Million years ago there weren't any dinosaurs, they all died about 65 million years ago. It's a small thing but details matter, I mean what, did he just guess and hoped nobody would notice? well i guess it worked because i haven't seen anyone mention it. in a world with google and wikipedia there is no excuse, its just lazy!
I did like the "seize the dumplings" line, so not all bad.
