LONDON, June 8 (Xinhua) -- German researchers have
discovered a new species of dinosaur that measures barely more than six meters,
the British science magazine Nature reported on Thursday.
Researchers of the University of Bonn unearthed the
remains of at least 10 individual dinosaurs at a quarry near Hannover in
northern Germany and found after examination that the new species, Europasaurus
Holgeri, measured barely more than six meters from snout to tail, in comparison
to its more famous relative Diplodocus measuring a mighty 27 meters.
When the researchers found the bones, they thought
they were from juvenile dinosaurs, but examination revealed that the bones had a
structure like those of adult dinosaurs, and that in the largest dinosaur, which
measured 6.2 meters, the bones were fully developed.
The area where the bones were found would have been
largely flooded when the dinosaurs lived there, around 150 million years ago,
the researchers said, adding that food might have been scarce on the islands on
which the dinosaurs lived, favoring the evolution of smaller reptiles.
"The little dinosaurs must have lived on one of the
large islands around the Lower Saxony basin. This suggests that it is an island
dwarf species that evolved through a decrease in growth rate from its larger
ancestor," researcher Martin Sander who led the research was quoted as saying.
Similar, more recent, examples of such island
dwarfing have been seen on the Indonesian island of Flores, which until a few
thousand years ago was home to species such as dwarf elephants and Homo
floresiensis, a tiny human, the magazine reported. Enditem
