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/10.10…

For this month of December, as a Christmas holiday sale, all commissions are 30% OFF! 🎄🎁 If you would like to commission me for a scientific article, book, etc, now its the time do so! More INFO: artofpedroandrade@gmail.com A Like and/or Retweet is apprecitated as well! 😁

New paper out: Nanotyrannus is a different species, not a juvenile T. rex. Growth record of the throat bone in the original skull of Nanotyrannus shows this is a grown-up individual, rather than a growing teenager, that lived alongside the tyrant lizard. science.org/doi/10.1126/sc…

Our teammate @victorlr15 , with his advisors @EduardoSuchus and Miguel Moreno Azanza; has published a new work on the classification of #Phytosaur mandibles with the usage of 2D #GeometricMorphometrics! 🐊 onlinelibrary.wiley.com/doi/10.1002/sp…

Whew. A little thing happened today. Honored to have done this work with the outstanding @JGN_Paleo. I was a skeptic when I stepped into this, but no denying it #Nanotyrannus is valid. @JGN_Paleo and I left no stone unturned. And by the way, there are juvi T. rex, stay tuned...

🧠🐊New paper on dwarf Jurassic crocodylomorphs from Portugal! We reconstructed the brain and inner ear of a 150 Ma dwarf crocodylomorph, the first palaeoneuroanatomical study ever done on Atoposauridae. Here is the link to the article: fr.pensoft.net/article/167846/

After so many years it is great to see the Angolan dyrosaur croc published! 🐊 Congratulations to @PalaeoFil @EduardoSuchus 👏🏽 academic.oup.com/zoolinnean/art…

8/ Huge thanks to our amazing international team and the @PaleoAngola Project. This study adds an exciting new chapter to the story of Africa’s ancient crocs! 🐊 #Paleontology #FossilFriday #Angola #Cretaceous #Crocodylomorpha #Science

1/🦴 New fossil croc from Angola! A ~70-million-year-old marine crocodylomorph has just been described from the Late Cretaceous of Bentiaba 🇦🇴. Proud to be 2nd author on this new paper! 🔗 doi.org/10.1093/zoolin… 🧵👇

5/ From a paleobiogeographic perspective, this is one of the earliest records of dyrosaurid dispersal along the South Atlantic coast — an important puzzle piece for understanding marine reptile evolution in Gondwana.

4/ This fits into a bigger picture: While most marine reptiles went extinct at the K–Pg boundary, dyrosaurids survived and diversified — especially in Africa. Our find shows that this diversification likely started before the extinction event.

🌍 What structures life on Earth? In the 1980s, Brown and Maurer laid the foundations of macroecology with a simple, powerful idea: space, time… and FOOD. Where food is, how it's distributed, and who gets access to it.

It was a pleasure to contribute to this research on the preservation potential of the Latitudinal Biodiversity Gradient in the fossil record !

New paper by my friend Sofia Patrocínio: "The oldest definitive docodontan from central East Greenland sheds light on the origin of the clade" It was a pleasure to illustrate the new taxon, Nujalikodon cassiopeiae, for this paper! LINK: doi.org/10.1002/spp2.7…
