We examine how derived functional signal and phylogenetic inheritance interact in the
forelimb of tree sloths, to understand the relative contribution of each in the evolution of a …

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 shapes and sizes of dermal bones of the palate of selected Palaeozoic
tetrapods in order to identify the ancestral states of palatal bone morphologies in the earliest …

Birds are the most diversified forms of modern terrestrial vertebrates. They are archosaurs,
and are related to Theropoda within Dinosauria. Even though bird morphology has been a …

Patterns of trait integration reflect the underlying genetic and developmental architecture of
morphology and significantly influence the direction of evolution. Nevertheless, the …

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

Hypotheses about constraints, selection, and other evolutionary processes often predict
different rates of change among different characters. For example, it is thought that gross soft …

Theropod dinosaurs are one of the most remarkable lineages of terrestrial vertebrates in the
Mesozoic, showing high taxonomic and ecological diversity. We investigate the cranial …

Pilosa include anteaters (Vermilingua) and sloths (Folivora). Modern tree sloths are
represented by two genera, Bradypus and Choloepus (both around 4–6 kg), whereas the …

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 …
