Última Reply to “Limusaurus and bird digit identity” Nature Precedings Xing Xu; James Clark; Jonah Choiniere; David Hone; Corwin Sullivan. Vargas et al. agree with us that a lateral shift in theropod dinosaur digits occurred prior to the origin of birds, but contend that it occurred as a single “frameshift” with little outward change to the three main digits involved^1^. We consider the digital morphology of Limusaurus, other ceratosaurs, and non-avian tetanurans to provide evidence that the shift was stepwise, and that a stepwise shift better explains theropod manual morphology than a hidden frameshift.

Nature Precedings Xing Xu; Jonah Choiniere; Corwin Sullivan; Fenglu Han. Tamura et al. (Science, 11 Febuary 2011, p. 753) claim that the three avian wing digits should be identified as digits I-III based on new embryological data and suggest that these identifications help to remove the conflict between the paleontological data and developmental data concerning the homology of the avian digits. However, their results are not novel, and the authors fail to address the critical problems relating to this interesting issue. Tipo: Manuscript Palavras-chave: Evolutionary Biology.
