A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorpha) and other “protorosaurs”, and its implications for the early evolution of stem archosaurs
Claudia Marsicano –– It is a welcome comprehensive analysis of a quite disparate group at the core of the early evolution of Archosauromorpha.
Feroxichthys panzhouensis sp. nov., a hump-backed colobodontid (Neopterygii, Actinopterygii) from the early Middle Triassic of Panzhou, Guizhou, China
Diogo Provete –– This manuscript describes the second species of a new genus of fossil fish
Divergent morphological responses to millennia of climate change in two species of bats from Hall’s Cave, Texas, USA
Brandon Hedrick –– The authors examine mandibular shape in two species of bats with robust 25,000 year old fossil records. Combining these data with climate and environmental data, they assess correlations between environment and mandible shape and size. These results are part of the growing field of conservation paleobiology and are useful in interpreting how changing climate impacts morphological evolution.
Age constraint for the Moreno Hill Formation (Zuni Basin) by CA-TIMS and LA-ICP-MS detrital zircon geochronology
Ian Moffat –– This paper provides important new information about the geochronology of the Moreno Hill Formation.
Maniraptoran pelvic musculature highlights evolutionary patterns in theropod locomotion on the line to birds
Brandon Hedrick –– The authors reconstruct novel pelvic myology of dinosaurian taxa and assess trends in muscle attachment site area across the theropod phylogeny. This work will be relevant to dinosaur paleobiologists working on pelvic morphology, locomotion, and macroevolutionary trends in soft tissues.
Ontogeny of highly variable ceratitid ammonoids from the Anisian (Middle Triassic)
Brandon Hedrick –– The authors examine ontogenetic changes in a group of Triassic ammonoids using geometric morphometrics to assess potential taxonomic diversity and over-splitting. These results are relevant beyond the locality that the authors focus on and have bearing on ammonoid paleontology more generally.
A new kentriodontid (Cetacea: Odontoceti) from the early to middle Miocene of the western North Pacific and a revision of kentriodontid phylogeny
Brandon Hedrick –– The authors describe a new species of dolphin from the Miocene based on a well preserved specimen and perform a phylogenetic analysis on kentriodontids and related groups.
Offshore marine actinopterygian assemblages from the Maastrichtian–Paleogene of the Pindos Unit in Eurytania, Greece
Kenneth De Baets –– The article describe new data from an important locality straddling the K-Pg event which is crucial for our understanding of this event on extinction patterns of teleost fishes.
The diverse radiodont fauna from the Marjum Formation of Utah, USA (Cambrian: Drumian)
Joseph Gillespie –– An important contribution to the knowledge base on Cambrian radiodont arthropods, with significant information regarding biotic diversity from the Marjum Formation of Utah, USA.
The ecomorphology of the shell of extant turtles and its applications for fossil turtles
Brandon Hedrick –– The authors present a study on turtle shell morphology using 3D geometric morphometrics to investigate the relationship between shell morphology and ecology.

There's a new Late Jurassic rhynchocephalian in town: Sphenofontis velserae, an exquisitely preserved sphenodontine from the Solnhofen Archipelago. Just out on @thePeerJ!

This amazing fossil, discovered by me and my mom, Lisa Marshall, at the Mother’s Day Quarry in Montana, exhibits several new scale shapes and orientations never before seen in Diplodocus. 2/8
