Eucamerotus foxi is a macronarian sauropod from the Wessex Formation (Early Cretaceous, Barremian) of the Isle of Wight. It is represented by NHMUK R2522, a partial dorsal neural arch, and differs from other known sauropods by the presence of a stout robust prezygoparapophyseal...

The Callovian Oxford Clay of England has yielded a rich and diverse marine fauna, mainly discovered and described by Alfred Leeds. However, occasionally it also brought forth terrestrial fossils, including four isolated cases of sauropod remains, one of a stegosaurid,...

The Dipnomorpha include the extinct Porolepiformes, in addition to Powichthys and Youngolepis and the extant Dipnoi (lungfish). As sister group to the Tetrapodomorpha, the Dipnomorpha hold a valuable place in our understanding of early sarcopterygian evolution....

The Middle Jurassic was a pivotal time for many vertebrate groups: recent research suggests mammals experienced a surge in ecological diversity at this time. However, vertebrate fossils from the Middle Jurassic are rare. Until now, Middle Jurassic mammals in the...

The village of Stolbovo, western Russia, has previously yielded a dipnoan fauna comprising the long-snouted form 'Rhinodipterus' stolbovi, but also a three-dimensionally preserved otoccipital region of a skull previously identified as the osteolepiform ‘Latvius’...

Interbasinal stratigraphic correlation provides the foundation for all consequent continental-scale geological and paleontological analyses. Correlation requires synthesis of lithostratigraphic, biostratigraphic and geochronologic data, and must be periodically...

Pterosaur embryos and ‘hatchling’ specimens show a surprising level of skeletal development including well-ossified skeletons and large wings. This has prompted interpretations of pterosaurs as being flight-capable from the earliest ontogenetic stages, contrasting...

During the last two decades, bioerosion of bone has become more widely investigated, with the earliest identified coming from mid-Triassic strata. Bioerosion has even been identified in bone fragments from a Jurassic theropod coprolite. Although the effects of...

A focus on cranial characters for determining relatedness is a predominant trait in many datasets, however this overemphasis can lead to distortion from sampler bias. We report on revised analyses of pachycormids - a key group within Actinopterygii, as part of...

The study of ontogeny in the fossil record is complicated by two main factors: growth series are not available for many taxa, and correctly assigning juveniles and adults to the same taxon is often difficult, especially where several related taxa coexisted. Ontogenetic...

Southern Africa provides critical information on Late Triassic–Early Jurassic terrestrial tetrapod faunas. Most of the localities in this region are in South Africa and Lesotho, but preliminary work in Zimbabwe has revealed significant potential. Early Jurassic...

The origin of the pterodactyloid bauplan from that of non-monofenestratan (‘rhamphorhynchoid’) pterosaurs involved extensive anatomical changes and had profound consequences for the evolutionary history of Pterodactyloidea, a clade that dominated the aerial realm...

The vastness of the vertebrate fossil record and its literature makes any effort to review it in entirety a difficult task; ‘a review’ is understood to be a work that discusses the evolution and diversity of a group, drawing in knowledge on taxonomy, morphology,...
