I think there’s a mistake on some of the date ranges that extend to the end of the Cretaceous. Didn’t check all of them, but according to Wikipedia, Psittacosaurus lived from 125–105 Ma, likewise with Iguanadon (126–122 Ma), but you have both up until the K-T boundary. There’s no way Megalosaurus, a single genus, existed from the Triassic to the end of the Cretaceous, right…? Forgive me if I’m missing something.

Makes you realize just how massive of a wipe out it was.

I think you are right on the publication bias. A single “pit” in Zhucheng hadover 7000 fossils in it alone. It’s crazy the amount of Dino discoveries there in the last 15 years. There is enormous interest from the public & government, so a lot of funding for it. I think they have now found as many species as the US did over 200 years!

How are these numbers tallied? There are well over 300 specimens of Anchiornis split between IVPP, STM and BMNHC. STM (Shandong Tianyu Museum of Nature) alone has 255 Anchiornis specimens catalogued in its collections in 2010.

Isn’t this a measure of which dinosaurs were dumb enough to get stuck in tar or buried in a landslide?
No disrespect to the dinos of course. Dying is what they do best!

If you follow someone like 7 Days of Science you find out that scientist are still discovering/naming new dinosaurs nearly every week.
