File this, I guess, under “the problem with Jurassic Park.”

The little claw at the bottom belonged to the fearsome Velociraptor, a category of creatures most of whom were about the size of a house cat ( like so ). The big scary claw up top belongs to Deionychus, closer to the size of a German shepherd… or the super-scary dinosaurs in the movie ( like so ).

The really scary uncle of these guys was Utahraptor, just for the record. About the size of a small car… and hungry.

The painting’s by Danny Cicchetti.
