Haplocanthosaurus and Allosaurus

A brontosaur Haplocanthosaurus is attacked by a carnivorous theropod Allosaurus in the Jurassic of North America. Based on the skeletal displays at the Cleveland Museum of Natural History which I saw yesterday(my first time drawing a dinosaur off of the fossils at a museum). More drawings of the other fossils, taxidermy and live animals at the museum to come!
