The palaeohistology of pterosaur bone: an overview
- L. Steel
- Geography, Environmental Science
Most pterodactyloid bones are predominantly composed of highly vascular reticular fi brolamellar bone, similar to that of most extant birds, which suggests that pterosaur bones grew rapidly, usually without interruption, until skeletal maturity was attained.
The Cranial Osteology and Feeding Ecology of the Metriorhynchid Crocodylomorph Genera Dakosaurus and Plesiosuchus from the Late Jurassic of Europe
It is hypothesized that trophic specialisation enabled these two large-bodied species to coexist in the same ecosystem and is supported by Plesiosuchus manselii having a very large optimum gape, while Dakosaurus maximus possesses craniomandibular characteristics observed in extant suction-feeding odontocetes.

It is concluded that there were three European Machimosaurus species and another taxon in Ethiopia, and it is hypothesize that Machimosaurs may have been analogous to the Pliocene–Holocene genus Crocodylus in having one large-bodied taxon suited to traversing marine barriers and additional, geographically limited taxa across its range.
Big-headed marine crocodyliforms and why we must be cautious when using extant species as body length proxies for long-extinct relatives
Examination and regression analyses of the best preserved teleosaurid skeletons demonstrates that they were smaller than previously thought, with no known specimen exceeding 7.2 m in length; and that they had proportionally large skulls, and proportionally short femora, when compared to body length.
Re-description of ‘Steneosaurus’ obtusidens Andrews, 1909, an unusual macrophagous teleosaurid crocodylomorph from the Middle Jurassic of England
The holotype of ‘S.’ obtusidens is re-described, it is demonstrated that it is indeed a valid taxon, the referred specimens are restricted to a fragmentary skeleton, nearly complete skull, and partial rostrum, and a new monotypic genus, Lemmysuchus is established.

The pterosaur collection at the Natural History Museum is of great historical importance, and many of the specimens were collected as long ago as the early 1800s, they are still useful today.

The dentition of Machimosaurus is comprehensively described and figure, and it is found thatMachimosaurus buffetauti and Machimosaurs hugii have four types of serration or serration-like structures, including both denticles and false denticles on the carinae.

It is hypothesised that the Bathysuchus + Aeolodon clade is the first known teleosauroid lineage that evolved a more pelagic lifestyle and has an extreme reduction in dermatocranial ornamentation and osteoderm size, thickness and ornamentation.
