Several studies have shown an increased morphological variability of sloths from
mammalian norms, affecting varied phenotypic traits from skeletal parts to soft tissues. We …

Animals with large differences in body size between adults and juveniles will often exhibit
differences in behavior through ontogeny, and these behavioral differences can sometimes …

Despite the restricted morphology and distribution of sloths today, fossils sloths show a wide
variety of forms and behaviors and used to range from South America to Alaska. These …

Sloth morphological evolution has been widely studied qualitatively, with comparative
anatomy and morpho‐functional approaches, or through quantitative assessments of …

Background Skulls serve many functions and as a result, are subject to many different
evolutionary pressures. In squamates, many fossorial species occupy a unique region of …

Sloths, like other xenarthrans, are an extremely interesting group of mammals that, after a
long history of evolution and diversification in South America, became established on …

Several studies investigating macroevolutionary skull shape variation in fossil reptiles were
published recently, often using skull reconstructions taken from the scientific literature …

We performed an exploratory analysis of the morphology of the cranium in the white olm
(Proteus anguinus anguinus) and the black olm (P. a. parkelj) with micro-CT scanning and …

Sloths are represented today only by two distantly-related small, arboreal, and folivorous
genera. However, the fossil record of the clade is composed of many more taxa, with much …

We examined the morphological diversity of the quadrate bone in squamate reptiles (ie
lizards, snakes, amphisbaenians). The quadrate is the principal splanchnocranial element …
