The oldest known embryos of a dinosaur

"Palaeontologists have identified the oldest known dinosaur embryos, belonging to a species that lived some 190 million years ago. The eggs of Massospondylus, containing well-perserved embryos, were unearthed in South Africa back in 1976.
The cientifics used the embryos to reconstruct what the dinosaurs babies might have looked liked when they were live. 

The team led by Professor Robert Reisz of the University of Toronto Mississauga (Canada), have discovered that the embryos were the oldest ones ever found of any
Having studied the fossilised eggs, the team, led by Professor Robert Reisz of the University of Toronto Mississauga in Canada, discovered that the embryos were the oldest ones ever found of any vertebrate. This project opens an exciting window into the evolution of dinosaurs.

Massospondylus belonged to a group of dinosaurs known as prosauropods. They were huge, four-legged dinosaurs with long necks.
The researchers studied the skeletons, which are 20cm-long, and they noted that the embryos were almost about to hatch, but unfortunately, they never had the chance.
Once hatched, the babies would have had rather long front legs, meaning that they would have been walking on all fours rather than on two legs like the adults.
 
What the dinosaurs might have looked like

The paper stated that the body of the embryos suggested that just like humans, the hatchlings would have required parental care - and if in this case, it would be the earliest known example of parental care."


A very interesting news. The news explain that they have discovered the oldest known dinosaur embryos, who lived some 190 million years ago.

Dinosaurs have always fascinated me, so I think that this news are exciting. I can't believe that they have found it! It's incredible... The science won't let us to surprise over and over. I hope that they will find a lot of news more about dinosaurs, because in my opinion they are very interesting.  

It has been also a great step for the knowledge of the dinosaurs and his evolution, so the people can imagine better how were dinosaurs.

  1. This I did not know. Is so seriously?
    I like dinosaurs, especially the urniturins. I've always liked this kind of thing. So I'm watching an anime that goes dinosaur
