✨ Zavacephale ✨

New basal pachycephalosaurid/most complete pachycephalosaurid skeleton dropped

Trying to practice paleoart more and draw new prehistoric creatures when I get the time

Just found out the pachycephalosaurid from my dinosaur project thingy's formation has been described (the species is now named Brontotholus), so I went and dug up this concept drawing I did of them four years ago (sept. 2021)

Happy to have a name I can google now!

For #FossilFriday, it's a *NEW PACHYCEPHALOSAURID*(!), and a project that is very near and dear to my heart. Let's welcome #Brontotholus_harmoni!

Most likely it's more of a Pachycephalosaurus situation and almost entirely bone.

Happy #FossilFriday! Meet Brontotholus harmoni (MOR 480), a new pachycephalosaurid from the Cretaceous Two Medicine Formation of Montana. Named after former MOR Chief Preparator Bob Harmon. Bronotoholus was named this week in a @ZoolJLinnSoc paper by MSU alumnus @doublebeam and colleagues.

my therapist: primeval's dracorex isn't real and can't hurt you
primeval's dracorex:
a still from the show 'primeval' of their depiction of the pachycephalosaurid dracorex, while may just be a junior synonym of pachycephalosaurus. it looks wayyyyy too much like a dragon, it's very silly

No time for a full nostalgic palaeoart thread, but I still want to share one of my all-time favourite works of palaeoart: Wayne Barlowe's Homalocephale!
A Homalocephale, a flat-headed pachycephalosaurid, stands beside a rocky hill amid a pile of large stones. Its scaly, lightly striped hide blends in perfectly with its environment. It is barely visible even as it stands erect in plain sight, only its legs and tail obscured by stones.

Also love that Ned’s reiterated favorite dinosaur is pachycephalosaurus so when this new one shows up looking like a pachycephalosaurid blended with a triceratops, and he loses his mind with delight, I’m so happy

Day 29 of #Dinovember! We have the tiny pachycephalosaurid Homalocephale! #Dinovember2024 #Paleoart #Dinosaurs
The tiny pachycephalosaurid Homalocephale. It had a thick skull plate on the top of it's head like it's larger cousins. It stood on it's hind legs and was thought to have been a swift runner. It's body is a desaturated brown with yellow spotting down it's back and a cream underbelly. It's tongue and interior of the mouth is blue.

Wake up nerds. A new dinosaur just dropped!

Brontotholus harmoni, which means “Thunder Dome.”

It was a pachycephalosaurid, and lived in the Late Cretaceous of what is now Montana.

And like most other pachycephalosaurids, it’s mostly known from its skull.

Fossil of the day is Homalocephale. It was a late Cretaceous pachycephalosaurid from Asia. The one known species is H. calathocercos. The generic name means Even Headed. It is sometimes considered a juvenile of Prenocephale, but is often argued not to be as well.

Pachycephalosaurus.

Everyone's favorite dome-headed dinosaur of Hell Creek.

Thought of redrawing this dome-headed dinosaur in time since I kept this behind the scenes.

💚/🔄s are welcomed!

A Pachycephalosaurus, idly standing in the environment of the Hell Creek Formation of Laramdia in what's now Western North America, somewhere in Montanna. Originally drawn in January of just last year, I had to take my time to redraw the very pachycephalosaurid based from Beasts of the Mesozoic own interpretation of Pachycephalosaurus. (Credit to Creative Beast Studio for the design base here!)

Day 29 of #dinovember 🐡 - Homalocephale
Pair of Homalocephale calathocercos enjoy a drink in the floodplains of Late Cretaceous. This small dinosaur had a flat wedge-shaped skull instead of the more typical dome found in pachycephalosaurids.

Happy #FossilFriday from #Stegoceras! A pachycephalosaurid from North America, these were small (only a few meters long) herbivores/omnivores that lived ~76my ago. Their skulls preserve more frequently than their postcrania due to their robustness, so finding more than an isolated dome is a treat!
