 | | Two examples of the big boy's ancestor - who has been named Dilong paradoxus, meaning "surprising dragon" - were found by teams from the Chinese Academy of Sciences in Beijing and the American Museum of Natural History in New York. |
 | | But by the time T. rex had evolved from its ancestral tyrannosaurs like Dilong, it's possible that the huge animals no longer needed true feathers as adults - and instead were covered with scales because they needed to dump excess heat from their big bodies, very much the way elephants do today, Norell said. |
 | | In Dilong's time - between 129 million and 139 million years ago - the primitive tyrannosaurs must have lived around lakes amid the earliest true flowering plants, in a verdant forest of early conifers much like today's pines and ginkgoes, Norell said. |
