The making of a monster: postnatal ontogenetic changes in craniomandibular shape in the great sabercat Smilodon by Christiansen, Per

“…Derived sabercats had craniomandibular morphologies that in many respects were highly different from those of extant felids, and this has often been…”

Canine morphology in the larger Felidae: implications for feeding ecology by CHRISTIANSEN, PER

“…Canine morphology is analysed at seven intervals along the crown in both anteroposterior and lateromedial perspective in seven species of large felids. The…”

Sabertooth characters in the clouded leopard (Neofelis nebulosa Griffiths 1821) by Christiansen, Per

“…The clouded leopard (Neofelis nebulosa) is an unusual medium‐sized felid whose ecology in the wild is poorly known. Mainly famous for its large canines, it has…”

Variation in craniomandibular morphology and sexual dimorphism in pantherines and the sabercat Smilodon fatalis by Christiansen, Per, Harris, John M

“…Sexual dimorphism is widespread among carnivorans, and has been an important evolutionary factor in social ecology. However, its presence in sabertoothed…”

Bite forces, canine strength and skull allometry in carnivores (Mammalia, Carnivora) by Christiansen, Per, Adolfssen, Jan S.

“…Skull variables were analysed for allometry patterns in 56 species of extant carnivores. As previously reported, many skull variables scale near isometrically…”

Salient features in the locomotion of proboscideans revealed via the differential scaling of limb long bones by KOKSHENEV, VALERY B, CHRISTIANSEN, PER
