Abstract
Using computed tomography, we discovered labial cartilages (splanchnocranial components) in an enigmatic lamniform shark, Odontaspis ferox (smalltooth sandtiger). We demonstrate that the presence of labial cartilages is plesiomorphic in Lamniformes, affirming that their "reduction" cannot be used as a synapomorphy for the order. Rather, their loss occurred through lamniform phylogeny.
