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 ...
The relationships of the Euparkeriidae and the rise of Archosauria
(2016)
For the first time, a phylogenetic analysis including all putative euparkeriid taxa is conducted, using a large data matrix analysed with maximum parsimony and Bayesian analysis. Using parsimony, the putative euparkeriidDorosuchus ...
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 ...
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 ...
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 ...
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 ...
Tooth serration morphologies in the genus Machimosaurus from the Late Jurassic of Europe
(2014)
Machimosauruswas a large-bodied durophagous/chelonivorous genus of teleosaurid crocodylomorph that lived in shallow marine and brackish ecosystems during the Late Jurassic. Among teleosaurids, Machimosaurusand its sister ...
