Tiarajudens eccentricus and Anomocephalus africanus, two bizarre anomodonts (Synapsida, Therapsida) with dental occlusion from the Permian of Gondwana
(The Royal Society, 2015)
Anomodontia was a highly successful tetrapod clade during the Permian and the Triassic. New morphological information regarding two bizarre basal anomodonts is provided and their palaeoecological significance is explored. ...
The cervical anatomy of Samotherium,an intermediate-necked giraffid
(2015)
Giraffidae are represented by many extinct species. The only two extant taxa possess diametrically contrasting cervical morphology, as the okapi is short-necked and the giraffe is exceptionally long-necked.Samotherium ...
Baleen boomand bust
(The Royal Society, 2015)
A new, fully dated total-evidence phylogeny of baleen whales (Mysticeti) shows that evolutionary phases correlate strongly with Caenozoic modernization of the oceans and climates, implying a major role for bottom-up physical ...
Morphological and functional changes in the vertebral columnwith increasing aquatic adaptation in crocodylomorphs
(2015)
The lineage leading to modern Crocodylia has undergone dramatic evolutionary changes in morphology, ecology and locomotion over the past 200+Myr. These functional innovations may be explained in part by morphological changes ...
A new Early Oligocene toothed ‘baleen’ whale from western North America
(2015)
Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned ...
Evolutionary origins and development of saw-teeth on the sawfish and sawshark rostrum
(2015)
A well-known characteristic of chondrichthyans (e.g. sharks, rays) is their covering of external skin denticles (placoid scales), but less well understood is the wide morphological diversity that these skin denticles can ...
Diversification events and the effects of mass extinctions on Crocodyliformes evolutionary history
(2015)
The rich fossil record of Crocodyliformes shows a much greater diversity in the past than today in terms of morphological disparity and occupation of niches. We conducted topology-based analyses seeking diversification ...
Estimating cranial musculoskeletal constraints in theropod dinosaurs
(2015)
Many inferences on the biology, behaviour and ecology of extinct vertebrates are based on the reconstruction of the musculature and rely considerably on its accuracy. Although the advent of digital reconstruction techniques ...
