Humans of all age groups from children to great archaeologists have always been curious about the origin and existence of dinosaurs. Scientists at the University of Bonn and the Sirindhorn Museum have identified two new species of dinosaur which were based upon analyzing fossils discovered 30 years ago in Thailand.
The new species are distant relatives of the T.Rex dinosaur species but have a more primitive structure. Their work has been published in the journal Acta Palaeontologica Polonica. These fossils were discovered during excavation and were handed over to the Sirindhorn Museum. Adun Samathi who is pursuing the research came over these fossils five years ago. He is currently pursuing a doctorate at Steinmann Institute of Geology, Mineralogy and Paleontology at the University of Bonn. He bought these fossils here to use the state of the art facilities at the University.
These group of dinosaurs are called megaraptors which is a group of carnivores predatory dinosaurs including the Tyrannosaurus-rex(T.Rex). They run on hind legs and their arms are strong and armed with long claws. They have a more delicate head which has a long snout ending. Samathi has said that these fossils can be assigned to the bones of a megaraptor named as Phuwiangvenator. Phuwiangvenator was believed to be the fastest runner with a length of about six meters and shorter than T.Rex who is 12 meters.
The main group of megaraptors are found in South America and Australia however they are believed to be originated in Southeast Asia and spread across the globe from there. Various characters of the Phuwiangvenator group indicate that they originated from Southeast Asia. Further unidentified fossils were discovered by a group of researchers which are of a predatory dinosaur species of length close to 4.5 meters, however, the species could not be identified. Scientists assume that this second species is a smaller variant in the dinosaur species called the Vayuraptor nongbualamphuenisis is also related to Phuwiangvenator and T. rex. Samathi compares this condition with that of the African black cats where the Phuwiangvenator is a lion and the Vayuraptor is a cheetah.
The recent findings and all the hard work of the archaeologists in finding the two new predatory species will be made public and presented on the tenth anniversary of the Sirindhorn Museum. Thai Princess Maha Chakri Sirindhorn will open the event. In the field of archaeology, there is no end as new fossils will lead to discovering of new species and theories.
