From Belgian daily Het Laatste Nieuws:
An international scientific team has found the first burrow digging dinosaur species ever, the latest issue of Proceedings B of the British Royal Society says.
The plant eater Oryctodromeus cubicularis, unknown until now, lived some 95 million years ago and took care off its offspring in an underground burrow.
The animal was about two meter long; just the tail was 1.25 meter.
The fossil discovery in the US state of Montana marks a new page on dinosaurs, the team of David Varrichio of Montana State University in Bozeman says.
This newly discovered species is distantly related to iguanodons.
