Happy to announce that our latest study with @houssayecnrs.bsky.social is now published in the @anatrecord.bsky.social. 🐧🦆🪿 doi.org/10.1002/ar.7... How does the inner structure of the limb bones of aquatic birds relate to their locomotor abilities? 🦴

The final chapter of my PhD is out!! What happens when graviportal taxa get dwarfed? We explore this in dwarf elephantids from the Mediterranean Sea, looking at the inner and outer anatomy of limb long bones. 🐘📄 With @houssayecnrs.bsky.social and U. B. Göhlich #GRAVIBONE doi.org/10.1111/pala...
Miniature giants: investigating limb long bone structure in dwarf proboscideans
Terrestrial vertebrates rely on their skeleton to provide structural support and allow the movement of the body. Heavy, graviportal taxa, such as extant elephants, exhibit numerous adaptive features ....

Penguins may look charmingly awkward on land, but new research shows their bodies are finely tuned for powerful, efficient movement both on land and underwater. Penguins “fly” underwater and their bodies have adapted accordingly. Hirsh et al.: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...
The backstory of this important bone was forgotten. However, we were able to identify it in archival photographs and an old newsreel clip from 1961 (from 0:39, filmhiradokonline.hu/watch.php?id...), which helped us determine its place of origin and find several related fragments.
It was a great honor and an adventure to work together with @camillebader.bsky.social on this unique Deinotherium limb bone. The analysis helped us better understand how the inner structure of this giant’s bones adapted to its enormous size. (Art: Tibor Pecsics - @griffworkshop5)

Out in @nature.com today, we shake up the ornithischian family tree. Remember those weird Late Cretaceous iguanodontians, the rhabdodontids? Well they're weird because they aren't iguanodontians. They're ceratopsians. Well, at least some of them are... www.nature.com/articles/s41...
A hidden diversity of ceratopsian dinosaurs in Late Cretaceous Europe - Nature
New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.
