Preparing @anatrecord.bsky.social swag for the upcoming PaleoConnected 2025 conference at Mizzou!
Beautiful paleoart reconstructions by Henry Sharpe (pseudosuchians) and Adam Hartstone-Rose (sabretooth cat).
🚨 New research on Triassic fossils from Brazil!
Dicynodonts were key terrestrial vertebrates of the Permian–Triassic. New study reveals Dinodontosaurus brevirostris—previously known only from Argentina—also lived in Brazil
Rodrigues de Souza et al: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
🦎 New study revises Czech baphetid fossils (Carboniferous stem-tetrapods).
Rediscovered type of Loxomma bohemicum = actually Capetus palustris
Remaining fossils = Baphetes orientalis
Phylogeny suggests Baphetinae may be polyphyletic
Barták et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
For centuries, anatomists debated true origin of levator veli palatini—vital for speech & swallowing. Researchers found it arises from cartilaginous Eustachian tube not petrous bone, reshaping understanding of vocal tract evolution
Pagano et al: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
We're pleased to share the abstracts from the 2025 International Symposium on Morphological Sciences held earlier this year in Lisbon, Portugal. It was an honor to sponsor and support this excellent conference:

🦴 New study shows trabecular bone in juvenile talus shifts from genetic programming in infancy to adapting with bipedal gait. The most significant changes occur b/w ages 1–8, w/later growth-driven refinements continuing after age 8.

Thanks to my awesome co-authors Annie Burrows, Adam Hartstone-Rose, and Mike Jensen-Seaman!
🐭 New study uncovers how rodents sense their own whisking phase: elastic segment at whisker base bends & twists, stimulating mechanoreceptors. This explains how whisking is encoded during both free-air movement and object contact
Haidarliu et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
New data on Jiucaiyuangnathus confusus (Lower Triassic, Xinjiang): new skull + partial skeletons show juvenile traits, 6 upper incisors, distinct canines, unique prootic morphology.

🦷 In rat molar development, ANXAs localize near blood vessels early, with ANXA2 co-localizing with the Ca²⁺ pump in odontoblasts. Signals fade postnatally, suggesting ANXA2 drives early dentin calcification.

Bone microstructure holds clues to life history. In springbok, growth marks in limb bones reveal age, stress events & skeletal maturity. New study links ages to histology, showing mid-cortical marks reliably indicate age before maturity
Heck et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
New study on duck-billed dinosaur Huallasaurus australis reveals no evidence of invasive air sacs in Ornithischia. CT scans show dense vertebrae, suggesting these dinos used a “pelvic bellows” breathing system—unlike saurischians.
Aureliano et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
🚨🧪We’ve just published a new paper!🚨
We peered inside the bones of duck-billed dinosaurs from Patagonia to uncover secrets of their physiology. And they are VERY distinct from both carnivorous and long-necked dinosaurs 🦕🔬 [+] anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Inner & middle ear shape in 57 primate spp shows ecology shapes auditory anatomy. Some support for Acoustic Adaptation Hypothesis—but Sensory Drive, especially under interspecies competition, better explains morpho-acoustic evolution

New morphometric analysis of Australopithecus afarensis maxillae shows:
1️⃣ High shape/size variation—comparable to gorilla
2️⃣ No allometry
3️⃣ No time trend
4️⃣ Low shape dimorphism
Key for testing hominin species boundaries

🐇 CT data from 300+ rabbits show smaller animals of domestic breeds have rel. larger teeth—unlike wild spp, where tooth-body scaling is more balanced. Could dental issues in tiny breeds point to missing theory of optimal tooth size?
Fasciati et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
Diet affects not just skull shape but bone quality too. In rabbits, tougher diets changed stiffness & hardness in jaw bones—but not braincase—suggesting region-specific plasticity. Implications for reconstructing feeding behavior!
