morphometrics

They then quantified their shape using geometric morphometrics and paired this with data they collected in the field on how these snakes lived and what they ate to explore the relationship between skull shape and ecology.

The researchers used a technique called geometric morphometrics, identifying landmarks on the bone, to capture the shape of the Haast’s eagle’s skull, beak and talons in three dimensions.

He and Allowen Evin, now with the National Center for Scientific Research in Montpellier, France, also took many photographs of each jaw and skull to do geometric morphometrics.

‘Mystery big cats’ in the Peruvian Amazon: morphometrics solve a cryptozoological mystery.

Therein, they argue that the Brindled wildebeest is actually a complex containing four species that can be reliably distinguished on the basis of cranial morphometrics.
