English: A photograph of a Lemur catta skull illustrating the osteometric points used to calculate the nine cranial measurements associated with nectar feeding in mammals. Coronoid process height (CPH): basal point on the angular process to the apex of the coronoid process. Palate width at M1 (MPW): the distance between the lateralmost point on the left M1 alveolus and the corresponding point on the right side. Minimum skull width at temporal fossa (MSW): breadth of cranium directly posterior to the postorbital bars. Bizygomatic width (BiZ): the greatest distance between the outer margins of the zygomatic arches, the distance between zygion points. Maximum tooth row length (MTR): the distance from the posterior edge of M3 to the anterior edge of the lower canine. Dentary depth at M3 (DD): the vertical distance from inferior margin of the mandible to the ectomolare of M3. Total dentary length (TDL): the distance from the posterior edge of the gonion to the alveolare (infradentale superius). Total palate length (TPL): the distance between staphylion and prosthion, which is sometimes called medial palatal length. Total skull length (TSL): the distance between akrokranion and prosthion. Akrokranion is the most aboral (nuchal) point on the vertex of the cranium.
