I'm pretty sure NHMG 8500 is the "Jiangxi Megaraptoran" but from what I've seen it's fragmentary as fuck. I'd rather call Maip the biggest megaraptoran for now, since it's way more complete. To be honest all fairly-complete Megaraptorans are cool imo.

NHMG 8500 is just a few teeth lol

That doesn't mean you can't estimate the size

It means such estimates are extremely unreliable, and it might not even be a megaraptoran to begin with iirc

Unless the teeth is similar

If there unreliable then how come scientists make them

Firstly, tentative estimates are a thing. Secondly, the figure comes from a book with a section dedicated to the biggest and smallest of different theropod clades, so naturally they'd want a biggest megaraptoran, and since those teeth look pretty big they're gonna go for that.

That isn't even mentioned in the article lmao

Mail obviously
