January 7, 2016, 15:41 Washington, Jan 7 (Prensa Latina) Experts believe that by mating dinosaurs had a similar behavior of certain birds today, according to an analysis released today by the journal Scientific Reports article.
The international team of researchers, led by paleontologist Martin Lockley, discovered large scratches on sandstone 100 million years ago in western Colorado.
These ancient scrapes are similar to those that caused a strange behavior in birds Today, the males show their skills digging a sort of nest to potential partners, a dance which leaves characteristic marks on the floor.
shorebirds, ducks, ostriches, pheasants, quail or falcons build their nests with this technique, according to the dinosaur tracks specialist and professor at the University of Colorado Denver, United States.
“These are the first sites where evidence of look mating rituals, and the first physical evidence of courtship behavior, “he said Lockley.
According to the magazine, paleontologist found the remains of more than 50 scuffing of dinosaurs, some as big as bathtubs in huge slabs located in areas where footprints of carnivorous dinosaurs and herbivores were also confirmed.
The scientists created three-dimensional images of scratches with a modern technique and rubber molds and fiberglass.
To Lockley, this new fossil evidence supports the theories of sexual selection as an evolutionary drive.
According to theories widely accepted in the scientific world, from prehistoric times males seeking couple trying to eliminate the weaker; and females, in turn, elect the strongest to breed.
“The fossil evidence rasping offers a tantalizing hint that dinosaurs could have gathered here millions of years ago to breed and then nest close, “said the expert
