Sharp-Toothed Fossil Links Old and New Dinosaurs
What's really neat about this is that it fills in one of the gaps in dinosaur evolution. The short snout and slanted front teeth of Daemonosaurus chauliodus had never before been seen in a Triassic era dinosaur, and this means it was one of the earliest known intermediates between the predatory dinosaurs of South America and the more advanced therapods. Mind you, having found only the head and neck of Daemonosaurus means that the scientists aren't really sure of its size as yet. You can also see another version of the article on the buck-toothed daemon reptile over on the Chinleana web site.
