"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." TIL some snails give birth???

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.

FLOCKING! Nanotyrannus (of course), Pteranodon, Phosphorosaurus, and Helicoprion #paleostream #paleoart #sciart

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.

Hello? Who's this?

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! #Minecraft #minecraftmodding #paleoart #dinosaur

congrats to both @zhejiang0pterus.bsky.social and @skyemcdavid.com for this publication!!! I had a lot of folks talk about how excited they were for this publication. Glad I could help out a teeny bit with it <3

Huge sections dedicated to 🌿palaeobotany🌿 love to see it

#temnovember2025 day 2: Acroplous 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 #paleoart #sciart #amphibian #temnospondyl #dvinosaurus #permian

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! #drawdinovember #dinovember2025

#temnovember2025 day 1: Adamanterpeton And so the annual madness of #temnovember beging with #Adamanterpeton, a small basal cochleosaurid from the late carboniferous of Linton #paleoart #sciart #temnospondyl #amphibian #edops #carboniferous

Navigator of the River Lethe #Nanotyrannus

Whelp, I suppose this is now Nanotyrannus lethaeus.

sometimes I am reminded how juvenile and immature the online paleo community can be...

Night at the Museum?

Saw something that @realgdt.bsky.social said the other day, and remembered I had something I started a while ago that I should finish up. I'm so tired of all this.

This stinks :c

After two years of hard work, I’m proud to announce that our new special exhibition @smnstuttgart.bsky.social is now open for the public – Meet Triassic Life: Dawn of the world of reptiles (1/7).

The new dragon designs in Pathfinder 2e's Monster Core 2 are kinda heccin' poggers, NGL...

Vetulicolian studies. Cambrian weirdos #sciart

After having to go through over 100 laggertätte OR near laggertätte fossil sites for wikipedia, lemmie tell, there's so many of them. You'd think these exceptional sites would be few and far between? not the case

Every time someone makes a strawman fallacy when I'm trying to discuss paleo all I can think of is the "I like pancakes" "so you hate waffles?" Twitter post. nothing else captures the sheer confusion and stupidness of that argument.

Papiliomaris kluessendorfae, first reported in 1985 as the Waukesha "Butterfly Animal", was recently described as a strange bivalved arthropod with three pairs of large, feathery appendages. Some reports indicate it could reach up to 20cm wide.

Multiple lobopodian fossils from the Chengjiang Biota of Cambrian China, including a specimen of two Diania cactiformis, have been found stacked directly on top of each other. Perhaps a snapshot into the courtship and reproduction of these ancient arthropod ancestors?

Oh hai! We're here now! Follow us for the latest articles published in the Journal of Vertebrate Paleontology!

Happy Croctober everyone! We just finished the prototype Deinosuchus schwimmeri, named in honor of David Schwimmer (not not THAT one) Holy crap this croc is BIG!

The Triassic was a time of weird reptiles of every description. This is one of the more recent finds: Mirasaura from France. It's one of the drepanosaurs, an odd group of arboreal reptiles with superficially bird-like heads and, in some cases, equally superficially feather-like appendages.
