Very happy to share our work on bone inner structure of Madagascar’s extinct sloth- and koala-lemurs 🦴🐒 Finally out on @ZoolJLinnSoc academic.oup.com/zoolinnean/art… A big thank you to co-authors @JAriasMartorell Carla Argilés Esturgó and Damiano Marchi! 1/6

@ZoolJLinnSoc @JAriasMartorell Strikingly, the largest koala-lemur emerges as a suspensory taxon. This would place it among the largest mammals known with this locomotor specialization, rivalled today only by orangutans. Stay tuned for more work on these bizarre extinct primates! commons.wikimedia.org/wiki/File:Mega… 6/6

@ZoolJLinnSoc @JAriasMartorell Femoral data identify suspensory/bridging arboreal species (tree sloths, orangutans, lorises). Inferring extinct taxa's locomotion, we confirmed previously proposed sloth-lemurs' suspensory habits (Figure from Alfieri et al. 2026 (CC BY 4.0), doi.org/10.1093/zoolin…) 5/6

@ZoolJLinnSoc @JAriasMartorell This allowed us to assess and statistically test how this anatomical level co-varies with locomotion in extant species. (Figure from Alfieri et al. 2026 (CC BY 4.0), doi.org/10.1093/zoolin…) 4/6

@ZoolJLinnSoc @JAriasMartorell We then quantified humeral/femoral trabecular bone in extant mammals and extinct lemurs. For the latter, we used traditional and more recent approaches to clean fossil trabecular bone structure. (Figure from Alfieri et al. 2026 (CC BY 4.0), doi.org/10.1093/zoolin…) 3/6

@ZoolJLinnSoc @JAriasMartorell We first identified links between limb trabecular bone and locomotion in a broad mammalian sample. We used published quantitative behavioural data to define ad-hoc locomotor categories. (Figure from Alfieri et al. 2026 (CC BY 4.0), doi.org/10.1093/zoolin…) 2/6

Very happy to share the preprint of our work on Quaternary subfossil lemur trabecular structure! Thanks to co-authors from @ICP_MCrusafont @UAB1968 and @Unipisa biorxiv.org/content/10.110…

@FunEcology @fieldpalaeo @LizzySteell @OliverDemuth @snsf_ch And here you can find the plain-language summary🙂 fesummaries.wordpress.com/2025/09/19/why…

I’m now happy to share my first postdoc work in its final, peer-reviewed version published in @FunEcology ! A huge thank-you again to @fieldpalaeo @LizzySteell @OliverDemuth Anne-Claire Fabre and to @snsf_ch besjournals.onlinelibrary.wiley.com/doi/10.1111/13…

Our study on the role of the #PETM on the early evolutionary success of salamandrids is out! Delighted to be part of this great project led by @LoredanaGamma, & with @andrewjhouse, Anne-Claire Fabre, & @mennecart_b #salamanders #climatechanges 🌡☀️⌛️ royalsocietypublishing.org/doi/10.1098/rs… (1/2)

Glad to share that my first postdoc work on bird wing bone inner structure macroevolution is currently out as a pre-print on bioRxiv :) A big thank you to my colleagues from @unibern and @Cambridge_Uni @fieldpalaeo @snsf_ch biorxiv.org/content/10.110…

New paper today about the evolution of the wrist along the dinosaur to bird transition: a bird-like configuration appeared in predatory dinosaurs first, as suggested by new exceptionally preserved hands of oviraptors and troodontids nature.com/articles/s4158…

Being close to submit my first postdoc results, I am glad to present further preliminary data on extant and extinct Strisores birds at #EAVP2025 in Krakow @grumpyDrFabre @fieldpalaeo @snsf_ch

🚨 I'm looking for #Postdoc opportunities starting this September! 🧑‍🔬🔍 I'm a highly motivated researcher with experience in R, network analysis, and multivariate statistics. My focus is on the evolution of ecosystems and biodiversity over deep time.

It's finally out! Together with Allison Yi Hsiang and @fieldpalaeo, we explored relative homoplasy in a range of bird matrices and introduce a new parsimony measure, the relative homoplasy index (RHI) (1/n) academic.oup.com/zoolinnean/art…

Finally! Congrats to all the authors and specially @smnebreda for persevering so much and probably the longest paper birth in human history

🦴✨ New publication alert! ✨🦴 A new study explores the ulnar morphology of 𝑃𝑙𝑖𝑜𝑏𝑎𝑡𝑒𝑠 𝑐𝑎𝑡𝑎𝑙𝑜𝑛𝑖𝑎𝑒, a small-bodied primate from the Miocene of Can Mata (NE Iberian Peninsula). What does its forearm reveal about catarrhine locomotion? 🧐 🧵👇

New paper co-led by @MadlenLang and myself, providing the most comprehensive analysis of the evolution of olfactory bulb size in living and fossil euarchontoglirans. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

@GNavalon @JournalofAnat @AmsonEli @AlessVeneziano Gracias hermano <3

@fabalfieri_ @JournalofAnat @AmsonEli @AlessVeneziano Ole ese tíoooo! Congrats man!

Our paper on primate fibula trabecular structure, published on @JournalofAnat with @AmsonEli @AlessVeneziano Damiano Marchi, Daniele Panetta and Piero Salvadori is finally out! Enjoy ;) onlinelibrary.wiley.com/doi/10.1111/jo…
