Journal of Anatomy, EarlyView.Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

A description of dental microanatomy and implantation geometry in Chamaeleonidae
Journal of Anatomy, EarlyView.A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

Zonation of the Upper Cretaceous in Japan
Zonation of the Upper Cretaceous in JapanA scheme of the zoning which is best applicable to the Upper Cretaceous in Japan and adjacent areas is tabulated, with zonal indices and ranges of principal associated species. The indices are species of Inocerami and ammonites of the superfamily Desmocerataceae.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, EarlyView.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
