‘Living Fossil’ Damselflies Get Their Own Families!

A large molecular study has confirmed what was thought for a while: some isolated groups with at most a handful of species each are so unique that they have no close living relatives remaining. Five new families were named and two were revived.

Inferring octopodoid and gastropod behavior from their Plio-Pleistocene cowrie prey (Gastropoda: Cypraeidae)

Predation is an evolutionary force shaping sea floor communities, with the record of drilling predation being particularly useful to study predatory behavior on short and long timescales. Most predatory drill holes are caused by gastropods, but octopods within Octopodoidea also produce characteristic drill holes, yet remain severely understudied in deep time.

Feeding Traces on a Pteranodon (Reptilia: Pterosauria) Bone from the Late Cretaceous (Campanian) Mooreville Chalk in Alabama, USA

Pterosaur remains are exceptionally rare in the Late Cretaceous marine chalks of Alabama and the few specimens found are typically very fragmentary. We report the occurrence of a metacarpal of Pteranodon cf. longiceps from the Mooreville Chalk (Campanian, 83 million years old) of Dallas County, Alabama.
