Masiakasaurus was a bizarre theropod, a species of predatory dinosaur, discovered in Madagascar and described by Sampson in 2001. It lived around 70-65 million years ago. What were most intriguing were its teeth. Unlike most predatory dinosaurs, the teeth of Masiakosaurus curled outwards and forward instead of straight down. This means it had a highly specialized diet, possibly of snakes and fish. Masiakasaurus was related to the noasaurs, small primitive predatory dinosaurs found only in the Southern Hemisphere (even though most fossils came from South America). It is no surprise that it is so "bizarre". The denizens of Late Cretaceous Madagascar included plant-eating heavily-armored crocodiles, large short-armed predatory dinosaurs, and even a flying dromaeosaurid, Rahonavis. Due to isolation a unique fauna had thus developed.
