18. 自恐龙复原图从1970年以来，许多研究指出现代鸟类极可能是兽脚亚目恐龙的直系后代。
Since the dinosaurs recovery plans since 1970, many studies have pointed out that modern birds most likely suborder Theropoda a direct descendant of dinosaurs.
Suggestions that they were the direct descendants of theropod dinosaurs (a group of bipedal meat-eaters that include Allosaurus, Velociraptor and Tyrannosaurus) caused quite a flap.
Perhaps the time has come to finally accept that archaeopteryx was just another small, feathered, bird-like theropod fluttering around in the Jurassic.
All these feather types have been found in fossil impressions of theropods, the dinosaur suborder that includes Tyrannosaurus rex as well as birds and other Maniraptorans.
Here we report an isolated theropod left metatarsal IV (IVPP V 18060) from the upper part of the Shishugou Formation, exposed at the Wucaiwan Locality in the northeastern part of the Junggar Basin.
Since then, however, scientists have found a number of well-preserved theropod fossils with many more featherlike structures, corresponding to downy feathers and feathers with vanes.
"Raptors look quite a bit like dinosaurs but they have much more in common with birds than they do with other theropod dinosaurs such as Tyrannosaurus," Ruben said.
