广袤的蒙古沙漠上，一个原角龙小家庭受到了两只兽脚亚目的恐龙的追击。正在孵化后代的孤独盗蛋龙母亲正警惕地注视着沙丘上发生的一切。盗蛋龙的化石首次是在原角龙的驻地被发现，骨架身下有一窝恐龙蛋，因此科学家曾经认为它是在偷盗原角龙的蛋的时候被愤怒的原角龙杀死的，盗蛋龙由此得名。但多年后，当科学家重新审视这窝蛋的时候却发现那不是原角龙的蛋，而是盗蛋龙的蛋！也就是说，盗蛋龙不是在偷盗，而是在保护自己的后代，盗蛋龙被大大地冤枉了。 A part of the world now occupied by Mongolia provides the setting for this 72-million-year-old scene. A small family of primitive ceratopsians belonging to the genus Protoceratops flees over the crest of a large sand dune, pursued by a pair of fleet-footed theropods from the genus Velociraptor. In the right foreground, a solitary mother Oviraptor observes the chase while guarding her nest of eggs. A pack of theropods belonging to the genus Sauronithoides pursues a flock of the flightless bird Mononykus in the middle distance, while a pair of ankylosaurs from the genus Pinacosaurus watches from a distant sand dune.(words from amnh.org)
