The armored dinosaur Kentrosaurus, reconstructed as a shallow-water-dweller, using its thagomizer to anchor itself in the sand as it stands up to breathe

Iguanodon, reconstructed as an aquatic animal

Corythosaurus, reconstructed with a fleshy breathing-proboscis extending from its headcrest

Diplodocus, reconstructed as an ocean-bottom dweller “grazing” on marine worms

Martin Wilfarth was a German researcher who in the 1940s claimed that Mesozoic Earth was experiencing super tides and that all dinosaurs were actually semi-marine animals. In a 3-part series I try to explore the how and why of his reasoning: www.manospondylus.com/2025/08/wilf...

All the #fossils I collected in Donkey Kong Bananza

Just finished the game and they absolutely nailed it. They made some pretty awesome remixes of your tracks.

So were these structures “solid” to the touch like leaves or actually fuzzy like feathers?

Do you think this means other drepanosaurs (like Megalancosaurus and Hypuronector) could have also had these “feather-scales”?

Speculative reconstruction of the dinosaur Corythosaurus with a fleshy trunk extending from its bony headcrest, used as a snorkel while the animal is submerged in water.

A teaser for a blogpost I am working on. Between the 1930s and 50s, German paleontologist Martin Wilfarth proposed that the headcrests on #hadrosaurs were actually attachment-points for snorkel-trunks. This was part of his wider ides that all #dinosaurs were tidal animals.

I think it’s beautiful

A compilation of videos I did with @cmkosemen.bsky.social discussing the #SilurianHypothesis: youtu.be/6ciSxFuDXCc?...

I noticed that I use “Yeah” way too often when responding to people I agree with. It’s getting repetitive. So instead I will use “Aye”, because then I can at least pretend to be a pirate while talking to someone.

Ah yes, the cake crab

Beautiful. Is that a large cloud formation on the lower left?

While you don‘t often see it in paleoart, there is decent biomechanical evidence that #glyptodonts were actually quite good at bipedalism. Here‘s a cute illustration from: onlinelibrary.wiley.com/doi/abs/10.1...

Reminds me of the cartoon plesiosaur woman I drew once

Anomodon’t tease me like that!

Found the comment again: www.manospondylus.com/2020/12/anti...

Peters really is… something. I even had him turn up at my blog once, where I remember he claimed nyctosaurs were, I quote, “bipeds supported by forelimbs”. David, what do you call an animal that uses its hindlegs and forelegs to walk?

@davehone.bsky.social stars in a new YouTube video, so guess who turns up in the comments section? Yup, chronically-online, 365-day blogger David Peters. That's my personal bat-signal, so...

Some kids are dumb. That’s what.

You’re right, mass appeal (maybe with children in mind) probably was a big factor.

In the beginning I had the feeling they were maybe purposefully making it basic so it would work well with controllers (it’s the same team that made the weird Xbox Zoo Tycoon after all), but they also to made Planet Zoo work on consoles.

Gastornis, a man-sized flightless bird stands at the forest‘s edge and looks out into the barren volcanic plains of inner North America

Gastornis, looking out into a changing Eocene world that is becoming increasingly less tropical. These birds were mainly forest dwellers, eating hard fruits and nuts, and likely went extinct due to habitat loss from climate change. I drew this for a story I‘m writing on my Patreon. #paleoart #birds
