Leg feathers in an early cretaceous bird
Article Abstract:
A fossil of an enantiornithine bird from the early cretaceous period in China that has substantial plumage feathers attached to its upper leg (tibiootarsus) is described. The leg feathers in the new enantiornithine are longer than those in Archaeopteryx when compared with the length of the tibiotarsus, and they appear to be more aerodynamic than the leg feathers in Archaeopteryx.
