Objectives
2 Account for the effects of anatomical variation (growth, sexual and individual variation) and functionally-correlated characters on bias in the dromaeosaurid evolutionary tree. The former will be largely built on a baseline created by studies of Velociraptor and Microraptor (including using the growth curve of Velociraptor), whilst the latter will be based on literature and dissection-based studies of modern birds (and crocodiles). 3 Use the new anatomical information to construct a new evolutionary hypothesis for dromaeosaurids. 4 Use the literature and the Paleobiology Database (paleobiodb.org) to time-calibrate the new dromaeosaurid evolutionary tree. 5 Reconstruct changes in dromaeosaurid body size, geographical distribution and living environment through time by tracing these data over the new evolutionary tree. 6 Use the new evolutionary tree and the traced data to reconstruct anatomical changes leading to the stiffened, rod-like tail and gliding capabilities. Explain the functional consequence of these changes using insights from modern birds.
