Lystrosaurus Group
A group of Lystrosaurus is settled about a stream embankment in South Africa during the early Triassic, some 245 million years ago. A small, meter-long dicynodont, Lystrosaurus was a survivor of the Permian extinction, continuing this group of mammal-like reptiles into the Triassic. Fossil remains of Lystrosaurus are found in Antarctica and South America, as well as South Africa, indicating that these three continents were once gathered into a single landmass during the late Permian and early Triassic.

The thecodonts were an advanced group of reptiles widespread in the early Mesozoic and Lagosuchus shows anatomical features suggesting an evolutionary link to early dinosaurs.

Rutiodon and Triassic Flora
A large Rutiodon lithodendrorum, a phytosaur, rests in a lowland freshwater environment of Petrified Forest National Park in Arizona during the late Triassic, some 225 million years ago. The small leaping dinosaurs are Reveultosaurs--or were. This little dinosaur was thought present among the Chinle fauna of Petrified Forest on the interpretation of some fossil teeth found in the park 25 years ago. More recently, however, the teeth have been determined to belong to a species of aetosaur (a non-dinosaur thecodont armoured reptile). So POOF!, Reveultosaurus has ceased to exist and this illustration is itself now a remnant fossil of an old, extinct idea. Otherwise, the image fairly represents the Triassic flora of Petrified Forest NP, including large conifers, various tree ferns, ferns, horsetails and cycads.
