A Dinosaur-Eating Mammal

Here are two concept sketches of the Cretaceous mammal Repenomamus.

It's an extinct badger sized animal who raided dinosaur nests.

I also made a maquette out of an air-dry craft foam.

The finished painting of is fully documented in a Gumroad tutorial called "The Mammal That Ate Dinosaurs."

The illustration appeared in an article on paleo mammals in Scientific American.
