Morphological disparity and evolutionary rates of cranial and postcranial characters in sloths (Mammalia, Pilosa, Folivora)
Sloth morphological evolution has been widely studied qualitatively, with comparative
anatomy and morpho‐functional approaches, or through quantitative assessments of …

Convergence and constraint in the cranial evolution of mosasaurid reptiles and early cetaceans
The repeated return of tetrapods to aquatic life provides some of the best-known examples
of convergent evolution. One comparison that has received relatively little focus is that of …
