Welcome to part – oh my god – seven in this seemingly eternal series.

Like me, I’m sure you want it to end so I can get back to writing about the innumerable other things on the list. Yes, we’re here, once again, for another instalment in the Too Many Damn Dinosaurs (TMDD) series. If you’re new to the whole thing, go back to Part 1 and see what this is all about; if you want to see all previous parts in the series go to the bottom of the article for the links (or use the sidebar). In the most recent articles, we looked at two assumptions inherent to the TMDD contention: that sauropod populations were similar in structure to modern megamammal populations, and that sauropods and other big dinosaurs were similar to Holocene megamammals in ecology and distribution. Here, we look at a third assumption, and it’s one that just won’t die.
