Phenomenal.

Poposaurus running simulations starting to get better than utterly ridiculous. Now just ridiculous.

New #DAWNDINOS paper!
We do predictive simulations of vertical height jumping in the Triassic theropod Coelophysis & extant (tinamou) bird Eudromia. Mainly as sensitivity analysis of what parameters are most important. We show how crucial tail mobility is.

Why Dinosaurs? The highly-anticipated documentary by Tony and James Pinto!

For those who haven’t seen it yet, the award-winning documentary @whydinosaurs.bsky.social is now available free on YouTube! You should definitely watch it if you have the time. I’ve embedded the video in my review here.

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of ...

Locomotor reassessment of Iguanodon, Ouranosaurus and Lurdusaurus (Dinosauria, Ornithopoda) using osteological correlates Large ornithopod dinosaurs have been successively described as quadrupeds, bipeds and facultative bipeds. Here we study the case of three ankylopollexians (Iguanodon bernissartensis, Ouranosaurus nige...

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are bas....

Reinterpretation of Bakiribu waridza from the Romualdo Formation (Lower Cretaceous) of Brazil: a fish not a pterosaur Fragmentary remains of fossil vertebrates from the Romualdo Formation (Lower Cretaceous) of Brazil, preserved in association with two fish were interpreted as two individuals of a new genus and specie...

Interesting preprint suggesting that recently described fossils from Brazil described as a new ctenochasmatine pterosaur, Bakiribu, preserved within a regurgitalite, instead represent the gill arch apparatus of an actinopterygian fish:

A diminutive tyrannosaur lived alongside Tyrannosaurus rex Whether Nanotyrannus lancensis represents a distinct taxon or an immature Tyrannosaurus rex is a decades-long controversy. The N. lancesis holotype is an isolated skull and ceratobranchials, but limb ...

A man in a Batman costume and a pregnant woman in a crowded subway car, their faces obscured by pixelation. Text on top of the image reads: "Fig. 1: An example of the experimental setting, with Batman and a woman simulating pregnancy stand in a crowded metro"

Science will often take you to unexpected and delightful places. In this study, researchers hypothesized that riders in a crowded subway car would be more likely to offer their seat to a pregnant person if there were someone in the subway car dressed as Batman 🧪🦇

A paper published in Nature reports the discovery of an early sauropodomorph in the Andes of La Rioja, northwestern Argentina. The finding expands the known diversity and geographic range of early dinosaurs and offers new insights into sauropodomorph evolution. go.nature.com/4984sqA #Paleosky 🧪

Here's a T. Rex bored to death trying to bite their own tail. My partner asked me to animate it in stop motion, after she watched a video about the very important topic of "could T. Rex chew its own tail like a dog". The puppet is still a work in progress 🦖

Latest Cretaceous megaraptorid theropod dinosaur sheds light on megaraptoran evolution and palaeobiology - Nature Communications Megaraptoran theropod dinosaur anatomy and evolution is unclear due to the fragmentary nature of most available fossils. Here the authors report a well-preserved, late surviving megaraptoran from Argentina that clarifies our understanding of the morphology of this group and potentially provides insights into its diet and feeding strategies.

New megaraptor discovered—with its final meal still in its mouth A croc bone locked between the 70-million-year-old predator’s jaws gives scientists a rare look into its life and possibly its last feast.

This week, a new megaraptor was described—found with its final meal still in its mouth!
