🐊 Largest survey of skeletal disease in living crocodilians! Nearly half showed osteopathologies, w/trauma most common. Skulls were hit hardest, and non-traumatic issues like inflammation and joint degeneration rose w/size & age.

🦴 New study reveals how teen growth and puberty shape the femur from inside out.
Analyzing medieval femora, researchers found sex-specific “medullary contractions” during adolescence—especially in females & varying by region

A new analysis of Dunkleosteus terrelli reveals its massive jaws were far more cartilage-rich than once thought, reshaping ideas about muscle layout, bite mechanics & feeding style. Time to rethink this Devonian apex predator.

This Halloween, meet the real masters of the night! 🦇
This study by Quinn et al. shows that Seba’s short-tailed bats use tiny sensory hairs on their wings to fine-tune flight — changing wingbeat and shape mid-air!

🦎 Early Pliocene fossils (4.2–3.2 Ma) from Megalo Emvolon, Greece reveal Varanus cf. marathonensis, likely atest record of this monitor lizard in Europe.
Morphology links it to Asian not African lineages (esp. V. flavescens)

🦇 Bat nasal bones (turbinals) reveal how form follows function. Echolocating bats have simpler, plate-like turbinals, while fruit-eating bats show complex, scrolled ones—especially Cynopterus sphinx & Artibeus jamaicensis.
