African wild dog (Lycaon pictus) paper now in @anatrecord.bsky.social's Feeding Biomechanics Special Issue! Using dissection & diceCT, we show powerful bites aren't just about bigger muscles—muscle architecture, skull mechanics & fascia may be key🐺 anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Proud to share our latest paper in out in Nature today on the origin of #snakes. We present Tametara mirim, an articulated 3D preserved stem snake from the Late Cretaceous of Brazil. Tametara helped us re-tell the story of snake origins in a novel way... www.nature.com/articles/s41...

A 5.3-million-year-old deep-sea whale necropolis in the Diamantina Zone - Nature
Researchers uncovered an enormous deep-sea accumulation of whale remains in the southeastern Indian Ocean, showing long-term, specialized ecosystems and an extensive fossil record that offers new insight into deep-ocean biodiversity and whale evolutionary history.

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.

New study on Tasmanian devil & other dasyurids reveals how forelimb muscle structure relates to behavior. Dissections & CT showed largely conserved musculature. Differences hint at specialization in prey processing & arboreal movement Bidaye et al: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
This is wild: the authors find evidence for giant, macro-predatory octopuses in Late Cretaceous oceans that might max out at *62 feet long,* comfortably large enough to attack, kill and eat mosasaurs
Earliest octopuses were giant top predators in Cretaceous oceans
Top predators drive changes in ecosystem structure. For the last ~370 million years, large-sized vertebrates have dominated the apex of the marine food chain, while invertebrates have served as smalle...

Well, it’s been in the works for a bit now, but I should probably share my research proposal with the JSPS was funded. I’ll be moving to Japan this September to work with the National Museum of Nature and Science on Pleistocene through modern food webs. Excited for the next big adventure!
Paleo folks in the western US: The Western Association of Vertebrate Paleontology conference will be held Feb 14-16, 2025 in Mesa AZ with the Arizona Museum of Natural History: www.wavp.us/wavp-2025/ WAVP is always a fun, low-key conference, great for early career researchers. Hope to see you there!
