Alvarezsaurus 2
were a group of odd looking theropods from the Cretaceous Period.

Their arms

Their arms are unusual in that in all genera except the most primitive, Haplocheirus, have rediculously short arms with 1-3 fingers and 1-3 claws.


Alvarezsaurs had beaks on their mouths. They had a lot of really small teeth.
