  • Mosasaur and Ammonites

    This open edition giclee (inkjet) reproduction is of a pastel illustration I did in 1989 for the children's book Living with Dinosaurs.

The circular, disc-shaped shells belong to ammonites, tentacled cephalopods that were abundant in the Cretaceous seas and regular food for mosasaurs.

  • Maiasaura Nesting Grounds

    This open edition giclee (inkjet) reproduction is of a pastel drawing I did in 1985 as a preliminary design for a larger mural for the Academy of Natural Science in Philadelphia (the larger mural painted by another artist). The image depicts a group of Maiasaura tending their earthen nest mounds near present Choteau, Montana. The reconstruction is based on fossi remains of these duckbill dinosaurs and their association with nest sites containing juvenile bones and egg shell fragments, all found in 80 million year old freshwater sediments in the Two Medicine Formation. This illustration started as a pencil drawing on thick bristol paper that soon looked too lackluster to finish, so, on a lark, I completed the image in pastel.
