This is very obviously not all megatheropods, but these are the ones that are semi-popular but don't get as much attention as the big 3

NHMG 8500

Torvo is literally just in Dinosaur Revolution and then like, 1 or 2 episodes of Dinosaur King as a bad guy dinosaur

Usually I'd say Siats considering it appeared once in a bad T. rex documentary and hasn't been seen since, but these guys definitely need the attention more

TORVOSAURUS RAAAAAAAAHHH

^^I definitely agree with Siats

Acro is already very popular. I would go with something like Mapusaurus.

I agree with Torvo though. Big Megalosaurus raghhh!

Torvosaurus has really only appeared Dinosaur Revolution, and IMO it kind of just feels more like an anime villain than an actual animal on there.

The way they introduced it was fucking RAW though. Made the Allosaurus look like an insect despite it being well known as a well rounded hunter, pushed the thing aside and stole its territory upon its arrival
