In honor of Baron Ferenc Nopcsa, the renowned dinosaur researcher and former director of the Geological Institute of Hungary, the SZTFH/SARA is organizing a memorial day.
The event will take place in Budapest on October 2, 2025.

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)
Our work with Zsófia Román (my former MSc student) is now published in @historicalbiology.bsky.social , Volume 37, Issue 3. In this paper, we have analyzed a particularly rich coprolite material using different methods to explore its paleoecological significance. 💩 🐟 🦭
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.

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.

🦴 How do proboscidean bones support such massive weight?
Chapter 3 of my PhD is out, a new paper diving into their bone microanatomy!

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...

New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.
