Newly discovered dinosaur species lived 85 million years ago:

It is the oldest dinosaur to have been found in the Coahuila regionSome dinosaur fossils unearthed eight years ago in Coahuila have led to the discovery of a new species that lived in Mexico 85 million years ago.Acantholipan gonzalezi, which belongs to the nodosaurus family, is the oldest dinosaur to have been found in the region.Paleontologists based their discovery after eight years of research on bones and bone fragments excavated in Ocampo in the northwest of the state, and believe that the young animal had died and its body was swept away by a river, later depositing it on what at the time was the coast.A team of paleontologists from Coahuilas Desert Museum, Chiapas and Germany judged that the remains were sufficiently distinct to be described as a new species, despite having only a partial skeleton to go on.

The animal would have weighed a little over half a tonne and measured 3.5 meters long. An adult would have been five to six meters long.technical information
