Something incredibly important about this paper is the recognition of how a huge swath of dog evolution didn’t involve them moving like the familiar wolves, foxes and pets of today. Think more like weasels or badgers for the smaller ones, while bears for the largest Miocene species.
I always look for paleo books at used books stores. There’s an awesome one in Ann Arbor (Dawn Trader) that has had some great finds!
After 7.5 years, I'm leaving my role as the UMMZ µ-CT lab manager at the end of July. This has been the most productive, and fulfilling period in my scientific career so far. I'm proud to say I've trained over 20 students, contributed to several publications, and generated over 12,000 µCT datasets.
My paper on Mesocyon is finally out! This will be part of a special issue on John Day Fossils Beds National Monument. Art by Kaori Chambers www.cambridge.org/core/journal...
The first paper of the John Day Fossil Beds National Monument 50th anniversary special issue of the Journal of Paleontology is out online early! @virtpaleo.bsky.social, Jennifer Cavin, and Xiaoming Wang describe a nearly complete skeleton of the dog ancestor Mesocyon coryphaus.

Postcrania and locomotor function of Mesocyon coryphaeus (Canidae, Carnivora) from the Arikareean of North America
In this study, we virtually reconstruct the vertebral column of Pezosiren portelli, a four-limbed stem sirenian (Pan-Sirenia, Prorastomidae) from the Eocene of Jamaica. We used three-dimensional models of various vertebrae obtained through surface scanning of fossil remains and we applied several algorithms for virtual repair, including retrodeformation of distorted vertebrae or mirroring missing processes from their bilateral counterparts. To quantify the regional morphology of P. portelli, we digitized a set of homologous landmarks, following a standardized protocol retrieved from previous morphometric studies on the evolution of the mammalian backbone. The results reveal a cervical region with relatively long spinous processes, as well as a thoracic region subdivided into prediaphragmatic and postdiaphragmatic regions with an unspecialised lumbar region. Both aspects reveal anatomical traits typical of terrestrial mammals, suggesting that P. portelli may exhibit a mosaic evolutionary pattern, showing postcranial traits typical of terrestrial taxa but also early aquatic adaptations found in its cranial skeleton. Finally, we briefly discuss the implications of morphometric analyses of the P. portelli vertebral column for understanding the evolution of axial features in other secondarily aquatic tethytherians.
