She added that more information was needed. He said he has found another fossil, in a private collection in China, that contains the mirror image of the supposed tail of the Archaeoraptor. Fossils often break in two when the rocks containing them are split in excavation. This is a completely new dinosaur. Paleontologist Stephen Czerkas, who bought the Archaeoraptor fossil at a gem and mineral sale in Utah, said Xu may be right.
Research is still ongoing.
But that is what we are all tending to believe. Still, Czerkas said the Archaeoraptor, even without its tail, remained a very important find. We're getting new information about the dromaeosaur we've never had before. Xu said he could not disclose further details about his find until he finished a research article for Nature magazine to be published later this year. He has invited U.S. scientists to visit Beijing to examine his find.
