Ancestor of T rex unearthed
The t-rex's ancestor which lived about 200 million years ago was unearthed in a diggin in southern Poland. It was about 5 meters long and it's biggest tooth was about 7 centimeters long.
WARSAW: Paleontologists digging in a brickyard in southern Poland have discovered the remains of a dinosaur they say is a previously unknown ancestor of the Tyrannosaurus rex.
The predator dinosaur, given the working name "the Dragon", lived around 200 million years ago, team member doctor Tomasz Sulej of the Polish Science Academy said.
It was five metres long and moved on two legs. Its longest teeth were 7 centimetres long. "This is a completely new type of dinosaur that was so far unknown," Sulej said. "Nobody even expected that members of this group lived in that time, so this gives us new knowledge about the whole evolution of the T rex group." The remains were excavated from a brickyard in Lisowice village about 200 km from Warsaw.
The bones will be further examined prior to giving it an actual name besides "the dragon". A predecessor of mammals called the dicynodon was also found at the same location.
