This fellow (or at least his skull) is on display at the Natural History Museum in Madrid, Spain. He is the only known genus of this species.
The skull is quite unusual. Initially, it has a very marine reptile feel (but make no mistake this guy is clearly a terrestrial theropod). Once you look closer you see horns that imply battle between rivals for the best meal, sexual partner and to be the one who leads the herd. I'll be interested to see his cousins once more specimens of the genus are unearthed.
