Summary
DescriptionMasiakasaurus knopfleri theropod dinosaur (Maevarana Formation, Upper Cretaceous; near Berivotra, northern Madagascar) 2 (15415407082).jpg |
Masiakasaurus knopfleri Sampson et al., 2001 theropod dinosaur from the Cretaceous of Madagascar (public display at Chicago's Field Museum of Natural History - reconstructed skull based on UA 8680 (University of Antananarivo, Antananarivo, Madagascar) and FMNH PR 2183 & other FMNH specimens (Field Museum of Natural History, Chicago, Illinois, USA)). This unusual, small theropod dinosaur had anteriorly-projecting teeth at the front of its snout. This would have given its bite a larger "footprint", which allowed for easier capture of prey, perhaps slippery prey such as fish. Classification: Animalia, Chordata, Vertebrata, Dinosauria, Theropoda, Noasauridae Stratigraphy: Anembalemba Member, Maevarano Formation, Maastrichtian Stage, upper Upper Cretaceous Locality: near Berivotra, Mahajanga Basin, northern Madagascar Reference: Sampson, S.D., M.T. Carrano & C.A. Forster. 2001. A bizarre predatory dinosaur from the Late Cretaceous of Madagascar. Nature 409: 504-506. Theropod were small to large, bipedal dinosaurs. Almost all known members of the group were carnivorous (predators and/or scavengers). They represent the ancestral group to the birds, and some theropods are known to have had feathers. Some of the most well known dinosaurs to the general public are theropods, such as Tyrannosaurus, Allosaurus, and Spinosaurus. |
