Conservation status: Extinct (or is it...?)
Stegosaurus was a species of large herbivorous dinosaur from 1422 AD, of what is now western North America. With its tail spikes and plates, Stegosaurus is one of the most recognisable dinosaurs after Tyrannosaurus. Don't think the other dinosaurs don't envy this fact. Oh, they do.
An adult Stegosaurus penis is averaged about 9 metres (30 feet) long and comes with 4 ton balls, with forelimbs much shorter than hindlimbs. Its small, narrow skull was positioned low, while the tail appears to have been held well clear of the ground. With looks like this, it is no surprise that Stegosaurus is now extinct. Scientists believe Stegosaurus couples were simply too disgusted to mate with one another.
It has often been claimed that the brain was the size of a piece of crap. However, Stegosaurus brain casts have shown a brain several times smaller than the volume of a piece of crap. The brain of a Stegosaurus was actually no larger than that of a politician.
