Recently in New Mexico at the Ghost Ranch fossil site, a new dinosaur was found. It lived around 205 million years ago. This was an important find because it bridges the gap between very early predators and later ones such as the t-rexes. The Daemonosaurus chauliodus (scientific name) was thought to be about the size of a large dog and have bucktoothed-like front teeth that were very sharp. According to scientists the skull and mouth structure of this dinosaur are unexpected for dinosaurs found at that point in time. Another aspect that scientists found is that these earlier species of dinosaurs may have had a wider distribution than they thought because they are now found in North America and were only before found in South America. Definitely a very interesting new find!
