Fauna from Upper Cretaceous Argentina pt. 1
My illustrations for the thesis of a recently graduated palaeontologist. It's been an honor to work on this project and contribute in some way on the field of palaeontology. These are animals from the Upper Cretaceous of West-Central Argentina. The pseudosuchians Notosuchus and Comahuesuchus, the theropod dinosaurs Achillesaurus and Velocisaurus, and the early snake Dinilysia. The rest of the animals are not based on fossil skeletons found by the team but are the likely authors of the fossilized burrows. For the spiral burrows, a small mammal or a big lizard. For the insect burrows, ants or termites. For the more simple burrows, a crayfish.
Notosuchus terrestris, a small, terrestrial relative of modern crocodiles.
Achillesaurus manazzonei, a small theropod dinosaur, possibly insectivorous.
A crayfish, whose fossilized burrows have been found.
Ant and termite, whose fossilized burrows have been found.
Three types of fossilized burrows that have been found by the team of palaeontologist students.
