The Anatomical Record

New study reveals 2D morphometrics captures major patterns of fish body shape variation but can underestimate subtle 3D features. For broad comparative studies, 2D is often sufficient; for fine-scale morphology, 3D remains essential Torgersen et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

New evidence from ~10 Ma Tapar locality (India) strengthens its Late Miocene age. Fossil shrews, rodents & large mammals match fauna from lower Nagri Fm, while diverse mammal community points to resource-rich coastal woodlands Choudhary et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar… #FossilFriday

🐰 What drives body shape evolution in rabbits, hares, and pikas? Changes in rib length & thoracolumbar region are main drivers of body shape diversity. Body size—not burrowing or locomotion—best predicts body shape & limb proportions Brice et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

How do leading tools compare for reconstructing CT muscle architecture? Xfiber & Goodfibes produce similar fiber length/orientation results in high-quality scans but Goodfibes is more sensitive to lower resolution & curved fascicles Zobek et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

How did primate hand function evolve? 🐒 Hamate bone morphology suggests natural selection shaped key hand traits linked to grip & locomotion. Suspensory behaviors evolved independently in gibbons & great apes Hunter et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

🦈 New insights from Kashmir's Permo–Triassic rocks! Rich fossil horizons reveal 1st non-dental chondrichthyan, highlighting clear Permo–Triassic transition & valuable clues to Earth's greatest mass extinction & recovery Shafi Bhat et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar… #FossilFriday

🦇 How do bats breathe, smell & echolocate through the same nose? Using simulations of 12 bat species, researchers found nasal anatomy—not echolocation strategy—shapes airflow. Unique nasal strands in horseshoe bats affect pressure & airflow Goodwin et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

New fossil evidence sheds light on the origins of Lepidosauromorpha. A newly described specimen of Cargninia enigmatica from Brazil reveals previously unknown jaw anatomy and supports its placement as a non-lepidosaur lepidosauromorph Soares Damke et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

Histology & micro-CT on hyperodapedontine rhynchosaurs reveals specialized teeth & jaw structures for processing tough, abrasive foods.

Long-bone cortical structure in diaphyses changes during growth via skeletal modeling. Femoral micro-CT comparison of humans vs chimps shows shared early remodeling but divergent cross-sectional shape tied to locomotion. Swan et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

Dental anomalies in Olduvai Gorge Hippopotamus (1.7–1.3 Ma) reveal high canine trauma consistent w/male–male aggression. Recurrent enamel hypoplasia indicates stress from seasonal fluctuations in Oldowan–Acheulean transition. Fidalgo et al: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…
