New contender for oldest dinosaur
Posted 05 December 2012 - 07:35 AM
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.
It walked on two legs, measured 2-3m in length with a large tail and weighed between 20 and 60kg.
The find suggests that many millions of years passed between dinosaurs' first members and their dominance on land.
"It fills a gap between what we previously knew to be the oldest dinosaurs and their other closest relatives," report co-author Paul Barrett, of the Natural History Museum in London, told BBC News.
"There was this big gap in the fossil record where dinosaurs should've been present and this fossil neatly fills that gap."

I always imagined the future as a time of more reason, empathy, and peace, not less. It's time for a change.
