The bones represent about 20 embryonic individuals of the long-necked sauropodomorph Lufengosaurus, the most common dinosaur in the region during the Early Jurassic period.
In North America, for instance, sauropodomorphs and ornithischians didn't even show up until after the Triassic was over, Irmis reports in an upcoming issue of Earth and Environmental Science Transactions of the Royal Society of Edinburgh.
