Uma nova espécie de pterossauro do Araripe, encontrada dentro de um vômito fossilizado de dinossauro 🤍. A natureza é linda! Kkk

Seja bem-vindo, Bakiribu waridza!

Also, if anyone is interested I am available for commissions! I try to make my prices reasonable, so if your a researcher that wants art for a paper, or just a fan of fossils, let me know and I can work something out with you!
I can finally share this!!! a huge Thanks to both @skyemcdavid.com and @zhejiang0pterus.bsky.social for allowing me to do a Nyctosaur for this poster!!!

New Lagerstätte just dropped

may I never rest
5+ new pterosaur specimens
2 new dinosaur specimens

“I don’t have time to talk about the dinosaurs and I don’t want to”

Strathaird should be considered a Lagerstätte

"The discovery of juvenile shells within adult Sinotaia quadrata—only the second fossil evidence of viviparity among viviparids worldwide—provides rare insight into ancient reproductive strategies."

For people who know the Wiki page of the Judith River Formation you will notice that Zuul is missing from here, that's because we chose the middle member. The lower Oldman Formation is basically the same around this time, so its in here too. Size chart by Montana

And here we go, result from the Judith River Formation #paleostream! This late Cretaceous formation might be full of charismatic megafauna but it is currently understudied and a total mess when it comes to stratigraphy. In this scene I wanted to focus on two aspects...

The stratigraphy of the Judith is sadly very messy and needs a lot of dedicated love and Research in order to figure out large scale correlates between it and Dinosaur Park, Oldman, and Foremost. This map I made shows how messy the stratigraphy can be.

Tonight’s flocking #Paleostream sketches (it’s been a hot minute): Nanotyrannus in the woods, Pteranodon over Protosphyraena, Phosphorosaurus + sturgeon lunch, and Helicoprion. #paleoart #sciart #cretaceous #permian #backinhell

from researching the Nightmare that is Judith And Belly River Group correlates, it has become abundantly clear we need some insane person to wander around the badlands of Alberta, Saskatchewan and Montana for a few years to actually figure out the stratigraphy.

This has some really useful potential applications to determine biological sex in hadrosaurs, which could make doing nuanced osteological comparisons of other features in male and female individuals easier. I guess only time will tell!
Happy #FossilFriday! These are tail vertebrae of the duck-billed #dinosaur #Hypacrosaurus (#MOR549). The arrows highlight #pathologies (injuries). This week, a new study by Bertozzo et al., suggests these pathologies may be caused by mating, indicating this dinosaur is a female.

Meet Bashanosaurus, a small stegosaur that still has osteoderm armor! They will be found in lower Shaximiao Formation biomes. This screenshot is in the Shaximiao Gallery Forest!

And now for the second day of #temnovember, we have #Acroplous, an a basal dvinosauroid from lower permian of northamerica, known from multiple localities and specimens

Notably, this site has the opportunity to be expanded further. I chose to ignore sites called lagertätten without corroborating sources within the previous sup. of the list of Lagerstätte papers since its clear that the authors haven't worked or seen enough of the material.
turns out I accidentally made the 317th largest article on Wikipedia because of my expansions and split to the "List of Lagerstätten" page. I still am nowhere close to done on improving the list and the main article, but currently its one of the most comprehensive list laggertätten in existence

And along with Robert Reisz, one of the few times the toxicity has come into public view. There are many bullies, harassers, thieves, and even men with Epstein connections who keep their positions and reputations despite the whisper network. Dinosaur paleo is not serious at all about cleaning house.

Dinovember Glow Up #1 - Allosaurus

This Dinovember I’ve decided to take a trip down memory lane, following the first prompt list I took part in back in 2018 but with an updated twist. First up this month, we have Allosaurus!
