The answer for #Guess that #Lego #Fossil is #Trierarchuncus, but I'll allow #Mononykus as well since theyre so similar.

Trierarchuncus is named after Captain Hook, of Peter Pan fame, because of the distinctive large claw on its hand.

Its believed that #Alvarezsaurids like Mononykus and Trierarchuncus were insectivores and filled the same niece as modern day anteaters. The large claw seems to have envolved to allow access into insect nests.

See you next week for another #Guess that #LegoFossil
