Dumbosaurus idiosa
(Extracted from http://wiki.mindcloud.org/wiki/Dumbosaurus_idiosa ;-D)
The oldest, and most-short lived of all Dumbosaur species.
Once the members of this species reached maturity, odd behaviours would start to develop. Males would bash their hard, dome-like heads against a rocky wall until its structure gave way and the beast buried alive. Females, upon noticing their reflection in lakes, spittle and other water bodies would try to attack their 'doppelganger' by submerging their faces till drowning.
No one knows how this species managed to breed but it is thought that their progeny are the other Dumbosaur species: Dumbosaurus stoopii and Dumbosaurus ignoratum.
