New paper out! I'm really happy to see this study published, it was my first real experience working with CT data during my master's Thanks a lot to Margot Michaud and @ornellabertrand.bsky.social for giving me this opportunity! No microanatomy (yet?) but beautiful endocast of musteloids 🦦

Harbor seals may be born ready for life in the water—but their skulls keep growing for years. In a study of 152 harbor seals, the craniomandibular system was found to reach functional performance early, then develop gradually, unlike terrestrial carnivores Steinbach et al.: doi.org/10.1002/ar.7...

Last PhD conference: SEB @sebiology.bsky.social in Florence. Had a great time alongside @johnnyakatura.bsky.social's lab! John also presented a great poster on our FEA project with Lisa Kean, in collaboration with Jordi @featunning.bsky.social Bonus: the Pisa natural history museum was incredible 🐳

Finally out! Trabecular structure in tamarins changes depending on their leaping distance! A collaboration with U. Nguyen, @fabioalfieri2.bsky.social, A. Licht and @johnnyakatura.bsky.social, using my #R package "indianabones". (1/2) #primates #BioAnth #bones #science 🧪🐒🦴🏺 doi.org/10.1002/ajpa...
Visualisation of the result of the 3D node density computation on the proximal epiphysis of tamarins (detail of Figure 2 of the linked paper). A: anatomical section shown in B, C and D; B: 3D visualisation of the section; C: section in 2D showing the trabecular structure; density of trabecular nodes in 3D, shown as a colourmap.

This is really incredible! "This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded." www.nature.com/articles/s41...
Fig 2 from paper: "a, A 3-m-long minke whale fall recorded during dives FDZ174/FDZ177 at 5,610 m depth. b, Close-up view of yellow box in a showing brittle stars Ophiambix sp. (white arrows) and scale worms polynoid (yellow arrows) on the cranium. c, Close-up view of white box in a showing numerous transparent tubes of the bone-eating worm Osedax sp. emergent from whale bone. d, A beaked-whale fall consisting of eight ribs and several thoracic vertebrae observed during dive FDZ178 at 5,609 m depth. Brittle stars Ophioscolecidae sp. and Silax sp. and chemosymbiotic vesicomyid bivalves Abyssogena southwardae are associated with these bones. Tubeworm Nicomache sp. occurs in the surrounding sediments. e, Close-up view of the white box in d showing three vesicomyid bivalves (white arrows) and brittle stars (yellow arrows). f, A whale bone recorded during dive FDZ173 at 4,625.2 m depth, dominated by gastropods Phymorhynchus sp. 1 (white arrows), polychaetes Nicomache sp. (yellow arrows) and Osedax sp. (orange arrows). g, The deepest whale fall, consisting of three elongated vertebrae of a beaked whale, with small gastropods (yellow arrows) on their surface, observed during dive FDZ163 at 6,788.7 m depth. The two red laser points are spaced 10 cm apart. Scale bars, 5 cm."

Interested in the shape variation of phocid long bones? Check out our new study led by Leonard Dewaele in @anatrecord.bsky.social 🦴Using 3DGM, we show that long bones capture variation between subfamilies but fail at species level, calling for caution in fossil taxonomy doi.org/10.1002/ar.7...

Using 3D vertebral models and Autobend, this study by Esteban et al shows pinnipeds have highly mobile spines, especially in the lumbar region. Different families reveal distinct flexibility patterns tied to swimming style and land locomotion. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
