First evidence of an epidemic in Late Triassic phytosaur community: Colossosuchus techniensis show aggressive periosteal “sunburst” bone growth & resorption. Likely bacterial osteomyelitis suppressed immunity & led to their demise.

Using microCT + elliptic Fourier analysis, Ribeiro et al show shape change in the mandibular symphysis is driven mainly by allometry, with continuous remodeling across development—not a shift at molar eruption. Read more: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

While >70% of bone strength variation is explained by structure, a new manuscript by Skedros et al shows that collagen fiber orientation (CFO) in deer calcanei also reflects compression vs. tension loading. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

🦖Bristol Channel reveals a new early croc relative! Bodenham et al describe Galahadosuchus jonesi, sister to Terrestrisuchus gracilis and part of Saltoposuchidae—a swift, erect runner from just before the end-Triassic extinction.

❤️🫀In honor of Valentine’s Day, let's set the record straight on a relationship: carotid bulb +carotid sinus. Often treated as the same, one is a dilation that shapes blood flow; the other a neural baroreceptor zone that senses pressure

An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia) Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake-like or worm-like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live i....
