This #fossilfriday we are very happy to share our new note about Andinotoxodon. It finally officially formalized name would help to improve taxonomic and phylogenetic analyses on toxodontids. Also, I'm so happy to work with excellent paleontologist and frined @therhinoscaros.bsky.social.

Pangolins possess a spectacular, dense network of diploic veins for brain drainage! In our latest study, we show that this pattern may also provide rare morphological evidence linking pangolins and carnivorans in the Ferae clade. Check it out here: academic.oup.com/zoolinnean/a...

#FossilFriday Ever-growing teeth don't always mean a grass diet! New microwear analysis reveals pachyrukhines, curious rodent-like fossil mammals, were primarily fruit & seed eaters 🍴, overturning traditional assumptions. 10.0.3.248/j.palaeo.202... @palaeontosoc.bsky.social @thepalass.bsky.social

Ever-growing teeth ≠ grass diet! New study on pachyrukhine notoungulates, rodent-like fossil mammals from Argentina, shows they were mainly fruit & seed eaters! #Paleontology #fossils @societyofvertpaleo.bsky.social @paleosoc.bsky.social @oupaleobiology.bsky.social 10.1016/j.palaeo.2026.113585

Happy to be participating in the CAPA 2025, in #Paraná, Entre Ríos, Argentina. 🤩 Presenting our works on south american native ungulates. Always a pleasure to share science and connect with colleagues. Great week! #Paleontology #FossilFriday @thepalass.bsky.social

ppgm: an R package for integrating neontological, palaeontological & climate data in a phylogenetic comparative framework onlinelibrary.wiley.com/doi/10.1111/... #SVP2025 @alexh-palaeo.bsky.social @datadryad.bsky.social @tamueccb.bsky.social

Flow diagram illustrating the workflow for the ppgm R package. It starts with an extant envelope, fossil data is added, the evolution of climate niche is modelled, and finally climate niche & palaeoclimate are matched to show potential range.

#FossilFriday is the perfect day to time-travel! Our Paleo-LILLO field trip through 14 ka-8 Ma formations was absolutely incredible! The thrill of uncovering ancient life, piece by piece, is a feeling like no other. Every fossil tells a story!

#FossilFriday 🇦🇷 Extinct mammals from the last 15 Ma! We revealed fascinating details about their locomotor habits and diet. From rhino-like forms and agile macraucheniids to rodents, we explored how ecological niches were shared in the Neogene. doi.org/10.1080/0891...
