Scientists in Brazil say they have
uncovered a new species of dinosaur.
The creature, identified from fossils, is thought to have
lived more than 200 million years ago, making it one of the
earliest dinosaurs known to science.
The research team, from the University of Rio de Janeiro,
says there are strong similarities with its creature and
remains discovered in Europe.
This lends weight to the view that the world's landmasses
were once joined as a single continent in Triassic times.
The fossilised remains were originally discovered in Agua
Negra, near the city of Santa Maria, in the southern state
of Rio Grande do Sul. They were found by an elderly man out
for walk.
His name was Tolentino Marafiga, so the new species has
been named Unaysaurus tolentinoi in his honour.
Based on the model of the dinosaur presented at the
National Museum of Rio de Janeiro, it would have weighed
about 70kg, been 2.5m long and up to 70-80 cm high.
It was most like a herbivore, say the
researchers. Dating work suggests it lived during the
Triassic Period, 225 million years ago.
What has intrigued the research team is the geography.
"Preliminary analysis shows that it is closely related to
the European Plateosaurus, principally found around
Germany," said Atila da Rosa, one of the researchers.
This support the hypothesis that the continental
landmasses we know today came out of a supercontinent
scientists have dubbed Pangea.
And it suggests that dinosaurs of similar species were
dispersed over vast areas.
