Dorsal view drawings of the neurocranium morphology of †Pseudorhina and Squatina. Landmark configuration on the neurocranium for the data set including †Pseudorhina acanthoderma (A). Landmark configuration on the neurocranium for the data set including only the extant species of Squatina (B). Definitions of the landmarks are detailed in Supplementary Table S1.
