I am ecstatic to share the first dinosaur species I describe so far: Hesperonyx martinhotomasorum (reconstruction by Victor Carvalho ).
This guy is a new small sized iguanodontian from the Upper Jurassic of Portugal.
Here's the link: tandfonline.com/doi/full/10.…

Hand painted artisanal science posters should be the new craze.

Quanto accaduto a Bologna è inaccettabile.
Sul decesso di Abderrahim Fakir è doveroso che vengano accertate eventuali responsabilità con il massimo rigore. La verità va ricercata fino in fondo, senza pregiudizi e senza sconti per nessuno.
Ma nulla può giustificare la violenza contro le Forze dell’Ordine. Chi ha scelto di usare questa vicenda come pretesto per mettere a ferro e fuoco la città, aggredire gli agenti e seminare violenza, mettendo a rischio anche l’incolumità di cittadini del tutto estranei ai disordini, non cercava la verità: cercava lo scontro.
Alimentare un clima di odio e di delegittimazione verso un intero Corpo dello Stato è un atto di grave irresponsabilità. Trasformare migliaia di donne e uomini in divisa in un bersaglio significa colpire chi ogni giorno serve l’Italia con professionalità, sacrificio e coraggio.

The cool animation made by @errequad for his master research !

New paper out! 🦴We studied an exceptionally preserved juvenile of Dysalotosaurus lettowvorbecki from the Tendaguru Formation using micro-CT scans, reconstructing ~40 bones hidden inside a rock block. @ThePalAss

Another example of how museum collections + modern imaging techniques can reveal spectacular hidden fossils. 🦖

This work resulted from the Erasmus+ and Master Thesis project of @errequad , carried out between Bologna University and University of Tübingen.
It has been a pleasure to see this taking shape as a co-advisor :) Enjoy!

The surprise? Neck vertebrae were fusing earlier than those further back in the spine — challenging the traditional “tail-to-head” model of vertebral fusion in dinosaurs.

INCREDIBLE WORK! Congratulations to the authors 👏🏽
Also some interesting implications for Iberian ornithopods...

New paper out today in @ThePalAss : onlinelibrary.wiley.com/doi/…
Co-led with @PalaeoFil (coauthors Federico Fanti & Miguel Moreno-Azanza).
Using the largest data matrix yet, we name a new sail-backed clade (Ouranosauria) & reassess Iguanodon taxonomy. 🎨 Artwork by Davide Bonadonna

🦖 Plot twist: iguanodonts didn’t start in the Cretaceous. Our study pushes their origin back to the Early–Middle Jurassic (~180 Ma) — revealing a long hidden history. 🔥 Plus: a new clade, Ouranosauria (incl. Ouranosaurus-like forms)🌍 Global by the Late Jurassic.@AAlechiarenza
