Sloths! Reminder that I have to finish that plate of the sloths that went extinct in the last 20,000 years

Therizinosaurs are, without a doubt, some of the most interesting groups of theropod dinosaurs

Here you have a selection of a few species that I reconstructed for the Fukui Prefectural Dinosaur Museum in Japan for their 25th Anniversary Special Exhibition

In late August Renesto et al. published a paper where they described a specimen of Lariosaurus valceresii that preserves the skin, even outlining the body and limbs as well scales. I must say that I am happy that it is very very close to what I had hypothesized 😍

It is great when your educated guesses or hypotheses get proven largely correct by the fossil record. Here is a link to the Renesto et al. paper https://sjpp.springeropen.com/articles/10.1186/s13358-025-00396-z

No. Not really. I just might do some minor adjustments to the squamation of L. valceresii

A megaraptoran skeleton! From the end of the Cretaceous!

Excited about the announcement of Joaquinraptor, the top predator down south when tyrannosaurs ruled the north. The Schwarzengger to T. rex's DeVito (at least in the arms category). My thoughts:

www.livescience.com/animals/dino...

Gigantic dinosaur with 'claws like hedge trimmers' found with croc leg still in its jaws in Argentina

Speedy megaraptor Joaquinraptor casali had big arms and claws like hedge trimmers that would have made T. rex's forelimbs look puny.

For the @nytimes.com, I wrote about Joaquinraptor, a new species from a very cool family of dinosaurs: long-armed, hook clawed (possible) tyrannosaur relatives from South America

The Megaraptor Had Giant Claws and an Appetite for Crocodilians

What? No. You might be confused with the lower beak.

Congrats to all the authors!

#ZAVACEPHALE IS FINALLY OUT! 🥳 Our first definitive Early Cretaceous pachycephalosaur! (~15 my older than the previous oldest pachycephalosaurs) And the first hand material for the clade! I can't tell y'all how much of a pleasure it was to review this paper! ☺️
