Palaeontologists have found what is likely to be the oldest known dinosaur, filling in a yawning evolutionary gap. A study in Biology Letters describes Nyasasaurus parringtoni, a new species from 10-15 million years before the previous earliest dinosaur specimens.
There is only one known species of the dinosaur: Giganotosaurus carolinii. It lived from 99.6 to 97 million years ago, during the early Cenomanian stage of the Late Cretaceous Period, or about about 30 million years before T. rex. First described in a 1995 study in the journal Nature, Giganotosaurus was, at the time, thought to be the largest carnivorous dinosaur.
