This week for #Fossilfriday we have another #Guess that #Lego #Fossil.

This one I would rate as medium. This small theropod is known from North America.

Hide your guesses behind a content warning, so others can guess without being spoilt. I will post the answer tomorrow (and to anyone who guesses correctly).

This was designed by me.
