Extended Data Fig. 3: Landmarks used to quantify cranial shape variation in Proteidae, Rhyacotritonidae, Salamandridae and Sirenidae.
From: Metamorphosis shapes cranial diversity and rate of evolution in salamanders
Landmarks used to quantify cranial shape variation in Proteidae (Proteus anguinus), Rhyacotritonidae (Rhyacotriton variegatus), Salamandridae (Salamandra salamandra) and Sirenidae (Siren intermedia). Sliding landmarks that describe the 14 bones and 19 regions of the cranium used in all shape analyses. From the left to the right: lateral, dorsal and ventral views of the cranium. See colors key in Extended Data Fig. 1.
