An illustration of a swimming theropod of the Early Cretaceous, created for Scott Persons of the University of Alberta to be included in a press package publicizing his new paper describing some interesting toe-claw-only tracks that were discovered in China. The dinosaur in the image is modeled after Sinocalliopteryx, one of the possible animals responsible for making the tracks - given the size and shape of the impressions, they were likely made by a large compsognathid (like Sinocalliopteryx) or a small early tyrannosauroid, swimming along and kicking in a sort of “dino doggy paddle” that left only toe-marks in the substrate.

Tyrannosaurus rex  The largest North American terrestrial carnivore of all time. Created for Dinosaur State Park in Connecticut.

Diplurus The Late Triassic / Early Jurassic freshwater coelacanth fish from eastern North America, Diplurus. Some coprolites have been found from the right geological strata, and due to their size and chemical composition scientists believe these fossil fish feces can be attributed to a large predator like Diplurus. I created this image for a new exhibit at Dinosaur State Park in Connecticut.

Batrachopus The Early Jurassic tracks known as Batrachopus were likely made by an early crocodylomorph. I chose Protosuchus as a model for the image. This image was created for a new exhibit at Dinosaur State Park in Connecticut.

Eubrontes The tracks known as Eubrontes were most likely made by Dilophosaurus or a close relative. Here a lone Dilophosaurus stalks the shoreline of an Early Jurassic lake, leaving tracks in the mud and snagging occasional freshwater coelacanth fish.
