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!

The final, formatted version of the Zanno & @jgn-paleo.bsky.social Nanotyrannus paper is out: Zanno, L.E., Napoli, J.G. Nanotyrannus and Tyrannosaurus coexisted at the close of the Cretaceous. Nature (2025). doi.org/10.1038/s415...

Our findings brought to life: Different climates, different integument, all sloths 🦥. #PrehistoricPlanetlceAge

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 SQUEAKS LIKE A BABY CHOLO!!!!!! www.youtube.com/watch?v=9i0R...

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...

@tetzoo.bsky.social gives us the "skinny" on recent developments in megathere integument among other things regarding sloths extinct and extant. tetzoo.com/blog/2025/10...

The first dinosaur eggshells from the Lance Formation. As for its identity, it could come from anything from Edmontosaurus to T. rex. www.app.pan.pl/article/item...

@edgescience.bsky.social is putting something together to commemorate #120YearsofTrex. Anyone is free to contribute by sending in a video ansering the question "What does T. rex mean to you?" youtu.be/WWqawo1qwAA?...

Now this is interesting! @grahancock.bsky.social, I would love to chat if possible.

Do you want to know something funny? John Hammond funded InGen through a grift in the Jurassic Park novel. Colossal's "dire wolves" are the real life pachyderm portfolio.

Just saw #JurassicWorldRebirth last night, and you know what "really" irked me: The animated segment playing in the museum stating how the "Neo-Jurassic age" proved catastrophic for the dinosaurs, because they couldn't adapt to cold climates.

With #Jaws50 falling on a #FossilFriday, the gaping jaws of 0. megalodon at @ripleysaquariums.bsky.social of The Smokies is an appropriate showcase!

Yet more evidence against the scale/feather false dichotomy in the form of scaly hands and feet in #pterosaurs in addition to previous publications showing that they were fuzzy too! www.scup.com/doi/10.18261...

Very interesting review paper on dinosaur physiology. Plus it's the first (proper) citation of our ground sloth thermoregulation paper! This is going to come in handy for preparing the sequel.

A new paper by Boscaini et al. provided some interesting insights into the evolution of body size in sloths, and why the large ones went extinct. Some of the points that the authors raise align with some of our findings back in January (possible 🧵) . www.science.org/doi/10.1126/...

If Colossal wants to salvage its reputation with the scientific community, their PR department needs to have long talks with their scientists before they go spouting things off in the press.

I've finally received my copy of @markwitton.bsky.social's King Tyrant! I've never been this excited to dive into a tyrannosaur book since @davehone.bsky.social's Tyrannosaur Chronicles as an undergrad. Here's hoping it feeds me more ideas to test in future papers. #FossilFriday

Having a sloooow #FossilFriday? Liven it up with a Giant Sloth! Seen @tarpits.org, Harlan’s Ground Sloths were the most common in that area of Ice Age California, but many species lived in the Americas and the Caribbean. 🦕⚒️🧪

Introducing Mosura fentoni, a new radiodont from the #BurgessShale. Paper here: doi.org/10.1098/rsos.2… Thi#fossilil species has 3 eyes, spiny claws, wing-shaped swimming flaps, and a unique abdomen-like body region.

How the mighty have fallen.

Yet another write up about our paper courtesy of @youngstownstate.bsky.social I am extremely grateful and fortunate to have such kind and dedicated mentors as Dr. Butcher and Scott Mckenzie on my academic journey. #FossilFriday ysu.edu/news/ysu-pro...

As the only member of the "X-Men" that undergoes true hibernation, pichis were a big point of comparison in the portion of our paper suggesting that some ground sloths could have done the same thing. #Pichisarejustpeachy

I'm published author!!!! youtu.be/qcFYTt7Vceo?...

CMNH was the first place where I saw mounted dinosaur skeletons, and cordially hosted Mercyhurst's geology department to take part in their first fossil fest. It is a shocking and disappointing revelation that staff members were being treated this poorly behind all of the wonder this place brought.
