Title: A new maniraptoran dinosaur from China with long feathers on the metatarsus. Author: Xu X, Zhang F. Journal: Naturwissenschaften; 2005 Apr; 92(4):173-7. PubMed ID: 15685441. Abstract: The unusual presence of long pennaceous feathers on the feet of basal dromaeosaurid dinosaurs has recently been presented as strong evidence in support of the arboreal-gliding hypothesis for the origin of bird flight, but it could be a unique feature of dromaeosaurids and thus irrelevant to the theropod-bird transition. Here, we report a new eumaniraptoran theropod from China, with avian affinities, which also has long pennaceous feathers on its feet. This suggests that such morphology might represent a primitive adaptation close to the theropod-bird transition. The long metatarsus feathers are likely primitive for Eumaniraptora and might have played an important role in the origin of avian flight.[Abstract] [Full Text] [Related] [New Search]
