January 2011: An International team of scientists have discovered the preserved skeletal remains of a previously unidentified theropod dinosaur in a rock formation on the border between Mongolia and China which dates back between 84 and 75 million years ago.

Listen here to Dr David Hone from the UCD School of Biology and Environmental Science, one of the international scientific team led by Professor Xing Xu from the Institute of Vertebrate Paleontology & Paleoanthropology, Chinese Academy of Sciences, Beijing.

The partial dinosaur skeleton includes bones of the vertebral column, the forelimb, a partial pelvis, and almost complete hind limbs. According to the international scientific team, this is the only known dinosaur specimen with one finger and claw at the end of each forelimb (or arm).

The discovery published in the scientific journal PNAS (24 Jan 2011) highlights the complex pattern of evolution in the hand of the theropod dinosaur group. This dinosaur group ultimately gave rise to modern birds.
