For the first time, researchers have unearthed fossil remains of three young dinosaurs snuggling together in sleep. The configuration of the three animals in the 70-million-year-old fossil suggests that they may have huddled together to hide or perhaps just to sleep. The fossil probably comes from Mongolia and was being illegally exported, where it was confiscated by Mongolian customs agents in 2006, a report in Nature says. Subsequently, it was analysed using geochemical analysis by paleontologists from University of Bologna, Italy, which indicated that the fossil probably comes from Bugin Tsav fossil site in the Gobi desert. The animals were identified as a type of oviraptorid – dinosaurs with short faces, long necks and toothless beaks.
