Description Not so well-known by the general public was the very interesting, yet short lived Dinosaur era called the Plantzoic Period. And one of the most interesting creatures of that Period was the Potatosaurus Dulcis.What's curious about this guy is that unlike his cousin, the dangerousPotatosaurus Rex, the Potatosaurus Dulcis was a totally herbivorous dinosaur and a very 'sweet' guy.He also, unfortunately, had no clue of what was going on around him... which ended up being the reason of his own extinction.=P
