I have come up with a new Dinosauria cladogram. The is classification is based on the new findings of Isanosaurus, a sauropod that lived in the Triassic and had its legs set at a slight "semi-sprawl."
| |---Sauropoda ·
| |---Prosauropoda º
| |?---Lagosachus & Marasuchus*
* The placement of Lagosuchus and Marasuchus is uncertain, it could be before Theropoda, Prosaurpoda, or it may not belong to the clade dinosauria.
º Some prosauropds were omnivorous based on a find in Nova Scotia this is just one reason that prosauropods may not belong with the sauropods in a clade known as sauropodamorpha.
· Isanosaurus shows features, such as slightly sprawling legs, that prove that sauropods did not evolve from prosauropods and that they were close to the "Proto-Dinosaur."
