American paleontologist found out that two of Oviraptor, who died 75 million years ago in China - a male courts the female. Most likely, the dinosaurs died together, for what scientists call them "Romeo and Juliet".

A couple of Oviraptor (feathered dinosaurs of the Cretaceous Saurischia) found in the Gobi desert (Inner Mongolia). They immediately dubbed "Romeo and Juliet", but scientific scrutiny nickname passed immediately.

According to lead author of the study Personsa Scott (Scott Persons) to determine the sex of a dinosaur is extremely difficult, as the soft tissue almost never leave traces in the fossil record. To resolve this issue, Persons and his colleagues compared the remains of Oviraptor with the anatomical structure of modern birds.

Scientists have found traces of long feathers on the tail Oviraptor. For these flight feathers were clearly useless. Rather, they serve the same function as the tail in modern Turkeys, peacocks and steppe grouse: to attract the attention of the opposite sex. Analysis of the pelvic bones Oviraptor have the flexibility of the tail and the presence of strong muscles - all this helped the dinosaur flaunting his tail during courtship dances.



Then, paleontologists have found that one of Oviraptor pelvis larger - clear evidence of sexual dimorphism (characteristic differences in the size and other features of appearance between males and females). "Although the size, age, and the main features of the anatomy of two Oviraptor did not differ from each other," Romeo "has large pelvic bones characteristic shape, which allowed him to shake a tail, attracting females. In" Juliet ", these bones were much smaller and are arranged easier "- said Persons.

However, that would not have happened with a couple in the wilderness, to whatever stage of relationship did not reach their romance, Oviraptor asleep sandy open or asleep sandstorm, saving them for mankind.
