Summary
A scene from the late Carnian of south-west Pangea (Gondwana), as represented by fossil remains from the Ischigualasto Formation, San Juan Province, Argentina. In the foreground is the armoured thecodont Stagonolepis, about 2.5 meters in length. In the immediate foreground is the cycad Pseudoctenis (with palm-like leaves), and to the left of Stagonolepis another cycad, Leptocycas (resembling a small palm). A bit further back and to the right is the early ornithischian dinosaur Pisanosaurus, about a meter in length, standing under a Dicksoniaceous fern tree. Further back are a small group of large (up to 2 meters long) herbivorous cynodonts of the genus Exaeretodon, which existed in great numbers worldwide during the Carnian. In the far background are conifers. Dipteridacean ferns and Dicrodium pteridosperms (seed-ferns) provide a luxuriant undergrowth
