Reisz et al. describe asymmetric tooth wear on the lower jaws of the early Permian reptile Captorhinus aguti. Applying statistical techniques to a sample of nearly 100 individuals, they determine that tooth wear is more prevalent on the right side of the jaw, making this the earliest evidence of lateralized feeding behavior in an early amniote.
