Yet another strike against the "large dinosaurs can't have any fibrous integument" narrative. www.nature.com/articles/s41...

A mammoth drawings from Arcy-sur-Cure cave,France. Outlined in red-ochre, this rotund, tuskless mammoth looks like a juvenile. At 28,000 years old, a product of the Gravettian culture, one of the oldest examples of cave art in Europe. The saddest mammoth from the Ice Age. 🦣😢🏺 #MammothMonday

Horner is famous in where I dig in Montana for telling a little girl that brought him a fossil to identify something to the effect of : I’d rather this thing turn to dust in the badlands than have you get it

The woolly mammoth, a mother and her child, venture past glaciers impossibly vast for today's world.

What Really Happened at Tanque Loma? #paleoart

Completely unsurprising as many have already said. Begging MOR to distance themselves from Horner's legacy akin to what AMNH has done with Henry Osborn.

*In epic movie guy voice*: "From the authors of the two greatest tyrannosaur books of the past decade comes...."

A very good review of a very good book. Plus, a lot of good information said on tyrannosaurid integument and nuances on how it would impact their thermoregulation.

This is not a model. This is a "fossilised" taxidermy of a Woolly Rhino, discovered in Starunia mine in Carpathian Poland (now Ukraine) in 1929. Dating to the Pleistocene, its exquisite preservation is owed to a mixture of brine, oil and clays. 🧵

Hot take: NIT (Nanotyrannus is Tyrannosaurus) is going to be the new BAND (birds are not dinosaurs).

Some people really do be like: "nah, our modern day image of dinosaurs is boring and stupid"...

The last bombshell paleontology discovery of a year of bombshell discoveries: Ammonites survived the K-PG extinction! www.nature.com/articles/s41...

2025 was a year packed with a multitude of discoveries, and I am grateful my first paper was among them. First order of business of 2026: Continue working on the sequel.....

shout-out to @literallymiguel.bsky.social for having his art featured in a new publication! the study by wilson and zonneveld describes feeding traces on the holotype of the bolivian glyptodont trachycalyptoides www.tandfonline.com/doi/full/10....

People always draw Nanotyrannus attacking Juvenile Tyrannosaurus, so I am doing something different

A very Merr Chrismas to all you hoomans out there, from Prehistoric Planet: Ice Age's Megalonyx family! Wishing you a safe and happy holiday! #PrehistoricPlanet #PrehistoricPlanetIceAge #paleoart #groundsloth #Christmas #meme

Result from the Talara tar seeps #paleostream! Like the La Brea tar pits this was Pleistocene death trap, however these fossils come from Peru so everything has a south american flavor. This piece is set at the beginning of the rainy season, with new green beginning to sprout...

Excited to announce that my second manuscript, “Fossilised Melanosomes Reveal Colour Patterning in A Sauropod Dinosaur” has been published in @royalsociety.org !! Diplodocus scales are complex and diverse, and it turns out their color patterning was even more so. A 🧵🦕 1/26

In light of @tessasaurus.bsky.social's amazing paper on paleocoloration of the MDQ Diplodocus, I would *highly* recommend those interested to check out @zhejiang0pterus.bsky.social's paleo color doc! they've done great work researching it and have been very responsive to sources I've found for it. 👇

Huge congrats to @tessasaurus.bsky.social et al. on this excellent paper regarding the first sauropod melanosomes! royalsocietypublishing.org/rsos/article...

26 years of intense debate that boarded on blood feuds and this all could have been resolved if we just cut open the hyoids of CMNH 7541..... Incredible work!

I second this!

Having digested all five episodes of #PrehistoricPlanetIceAge, I wanted to put together a thread of my 10 favorite segments from the series. Spoiler warning in case you haven't seen any of the episodes yet.

"But her real ice age superpower is taking life slowly. Because saving energy is vital when it's this cold." Best line of the first episode of #PrehistoricPlanetIceAge.

I feel the need to address some comments that have been popping up here and there regarding the #Eremotherium design for #PrehistoricPlanetIceAge. To people saying that our paper fully refutes a sparse coat of fur in this genus, here is what we actually say:

Nanotyrannus attacking a young Tyrannosaurus is super common in paleoart especially in the last few weeks. Won’t stop me from depicting it too. Enjoy the new #watercolor. #paleoart

Thank you, Reddit! #PrehistoricPlanet

So surreal to see something that you proposed in your first paper being brought to life later that same year. Can't wait to see more from #PrehistoricPlanetIceAge!

Results from the Nanotyrannus #Paleostream! First two are N. lancensis, 3 and 4 are N. lethaeus. You might notice some paleoart homages here ;) #BackInHell

Relevant to today's news #BackinHell

We are certainly going to look back and laugh about how this was once considered the flat earth theory of theropod paleontology.

From the authors of the two greatest tyrannosaur books published in the last decade:

Will it be a trick? Treat? or both?

Yutyrannus trio closing in on Dongbeititan 🦕 inspired by how the original material for Yutyrannus was a trio of individuals possibly indicating social behavior, and then the limited material for Dongbeititan includes a rib bone with a theropod tooth embedded! #paleosky #yutyrannus #dongbeititan

Happy #InternationalSlothDay! Crazy to think that our little paper has been all over the place in just a short span of time. From a write-up in the New York times, to consulting on a Nat Geo infographic, to possibly seeing behaviors that we proposed on AppleTV. Am dreaming?

Now is the perfect time to hammer the point that we did not argue that ground sloths were as slow as tree sloths and that slow metabolism =/= slow movements! Plus, two-toed sloths can make quick swipes when they need to.

So now you've seen TWO #PrehistoricPlanetaIceAge #sloths :) For thoughts on recent developments in sloth science, head on over to... tetzoo.com/blog/2025/10...

It was a great honor to be in this video by @edgescience.bsky.social about what makes the Tyrant Lizard King so special. Plus I can now say that I've been in a YouTube video with @arctomet.bsky.social. #120YearsOfTrex #TyrannOThon www.youtube.com/watch?v=yE5F...
