Scientists have uncovered a 70-million-year old nest filled with 15 baby dinosaurs in Mongolia, Discovery News has reported.

The round nest contains at least 10 complete fossil sets and measures 2.3 feet in diameter, researchers have said.

The researchers conclude that all the 15 dinosaurs show juvenile characteristics including short snouts, large eyes, and no prominent horns and large frills associated with adults of this species.

The babies were identified as the Protoceratops andrewsi, which were four-legged herbivores.

Researchers say the find provides unique insights in to the parental behaviour of the adult dinosaurs and reveals that the babies were kept in the nest and taken care of before they were big enough.

According to Live Science, researcher David Fastovsky, a vertebrate paleontologist at the University of Rhode Island, said, "It's quite striking that there are 15 juvenile Protoceratops here - that seems like a lot to care for.”

“But they were living in a harsh environment, so perhaps mortality rates were high. The evidence suggests they may have been overrun by migrating dunes during a sandstorm,” he adds.

Discovery reported the nest and the fossils of the babies are currently housed at the Paleontological Center of the Mongolian Academy of Sciences, Ulan Baatar, Mongolia.
