Pythagosaurus was a
dinosaur of the
Triassic era known for its odd bearing, being precisely halfway
evolved between two-legged carnivores and
quadrupedal herbivores. Pythagosaurus had a very straight tail and back leading up to a pointed crest, then dropping straight down into a flat face and form. Different specimens have been observed to have tails and crests of varying
angles, but whenever anybody bothered measuring either one they found it to be a
cute angle.
Pythagosaurus was a short lived species for multiple reasons. Firstly, it was only capable of moving over flat ground; attempting to move over even the slightest slope would cause it to tip over and become easy prey for its chief
predator, the Dimensiotrodon. This predator, while long thought to be quite
obtuse, nonetheless was apparently easily able to size up the back length of Pythagosaurus through some instinctive means of calculating the sum of the squares of its other two sides. Another cause of Pythagosaurus' downfall was its own strict diet, consisting primarily of
accountants. Since these did not exist, and would not evolve for millions of years after the Triassic, Pythagosaurus often found itself to be completely empty.
Although it largely died out in the early going of the Triassic, some strains of Pythagosaurus managed to evolve their way out of their sticky wicket, and were the ancestors of the modern Hyppotenopotamuse.
