Idk what makes them medium sized but I’ll just say Suchomimus and Utahraptor for now.

Suchomimus, I loved Suchomimus since 2020, I like it mainly thanks to it being a much more different Spinosaurid, it was less swimmer and more terrestrial like Riparovenator, which, iirc, was also less swimmer and more terrestrial.

Suchomimus is not medium sized its Giant sized.

Well, entire Megaraptora, i guess.

Well then, I guess my favorite one has to be either Neovenator or Deltadromeus.

Allosaurus and Siamraptor Id say

Neovenator is 12 m and Deltadromeus is 16

Allosaurus

That's not very medium sized

Xenotarsosaurus.

Suchomimus and Yutyrannus
