Filter-feeding ctenochasmatid pterosaurs flourished in the Jehol Biota. Here, a new wing skeleton of the ctenochasmatid Forfexopterus is described from the Early Cretaceous Jiufotang Formation in Jianchang, western Liaoning, China. Interestingly, it exhibits a skeletal maturity with co-ossified elements, but it is only about 75 % the size of the immature holotype, revealing a developmental variation of Forfexopterus.

We describe the first dinosaur skeletal fossils from the Dunvegan Formation of British Columbia, collected near the Pine River in 1930. These are some of the oldest dinosaur body fossils from British Columbia and western Canada. We identify these bones as partial dorsal vertebrae and ribs from an ankylosaur; ankylosaur footprints are some of the most common fossils in this formation and in this region.

The locality of Groß Pampau in northern Germany is famous for its rich marine mammal assemblage of the Miocene age. A newly discovered ear bone of a fossil sperm whale is described here with morphological characters so far unknown from other sperm whales. It remains unclear at this point if it could belong to a sperm whale whose fragments were discovered in the same locality or to another, already-described taxon, of which the ear bones are still unknown.

Forcipulatacea is one of the major clades of extant sea stars with 400 extant species described, but with fewer than 25 fossil species known. Thus, the identification of any new fossil representatives is significant. We reappraise Ophidiaster davidsoni from the Tithonian of Boulogne, France, which was assigned to another major extant group, and reassign it within a new forcipulatacean genus Psammaster gen. nov. A phylogenetic analysis does not place it within any existing forcipulatacean family.

Mennerotodus is a genus of fossil shark that lived during the Paleogene Period, between 65 and 38 million years ago, and was previously known only from Asia and Europe. In this study, new species of Mennerotodus have been identified in the USA from Alabama (Mennerotodus mackayi) and South Carolina (Mennerotodus parmleyi). Mennerotodus mackayi is the oldest of the species, suggesting the genus originated in the Gulf Coastal Plain of the USA during the Paleocene Epoch (~ 65 million years ago).
