We all love a good theropod, but I'll always be a Tri-guy at heart. So here's triceratops, covered in quills.

"Leaping Hell Chickens"

The newly discovered Caenagnathid Oviraptor-line dinosaur called Eoneophron infernalis (Dawn Neophron of hell). This emu sized theropod lived in the upper Cretaceous Hell Creek formation in South Dakota.

It was described as a new species from remains that were previously attributed to another Caenagnathid species called Anzu wyliei. The paper that described it, Atkins-Weltman et al. 2024, recovered it as closely related not to Anzu but another Caenagnathid called Elmisaurus.

Triceratops frill fragment showing blood vessel grooves. I’ve posted a picture about the grooves in horns before, but this small fragment of Triceratops frill shows how well it can be expressed there too. The blood vessels that originally laid in those areas would have fed the overlying keratin covering.

I meeean there’s also maybe Parasaurolophus, who is dubious in just the Hell Creek, and Dakotaraptor and Troodon, who are just dubious everywhere??

For the record - and nobody asked this, but I want to write something fun instead of do work - if I were making Goodbye Volcano High, I wouldn't really change anything plot-wise or anything, but I would have every character be based on something from the same place specifically at the end of the Cretaceous

so, because everyone loves Hell Creek, I'd probably pick Hell Creek. as basic as that is

Fang & Naser I'd probably keep as the Hell Creek Azhdarchid? I'm also open to making them "Styginetta" (aka the only thing that would live through the extinction)

Trish can stay Triceratops!

Reed would be Archeroraptor. or maybe Styginetta. I'm debating

Naomi would be Edmontosaurus

Rosa would be Leptoceratops

Sage would maybe be Avisaurus, or Styginetta, or Anzu

Stella would be Ankylosaurus

Ms Roberts would be a Tyrannosaurus

LJ I'd probably make a Pachycephalosaurus

alternatively, we could have fun and go all out with the Nemegt

Fang & Naser would be Therizinosaurus or the Nemegt Azhdarchid

Trish would be Deinocheirus or Therizinosaurus or a Chickenparrot

Reed would be Teviornis or Adasaurus

Naomi would be Saurolophus

Rosa would be Gallimimus maybe? Or Mononykus? Or a chickenparrot?

Sage would be Teviornis, or Brodavis, or Gurilynia?

Stella would be Tarchia or Saichania

Ms Roberts would be Tarbosaurus

LJ I'd probably make a chickenparrot of some kind (there are so many)

at least one person would be Deinocheirus, another would be Therizinosaurus, and another would be Teviornis. everything else is just what makes sense

honestly in both I'd probably exnay the pterosaurs and just do dinosaurs for my own sanity, as much as that'd piss off my pterosaur researcher friends

like I love the game, but man, I would have openly wept if they had stuck to one end-cretaceous ecosystem. like, we know what lived when and what lived with each other (... more or less...), I feel like more games should take advantage of that?

Immersive realism! In my dino-anthro game? It's possible!

A mated pair of Tyrannosaurus rex, female in the background and male at the foreground, roam through the forests of what is now South Dakota in search of prey, whether it be Edmontosaurus annectens, Pachycephalosaurus, Triceratops or Torosaurus.

My first T.rex drawing of 2024!

Hell Creek is Real-World Jurassic Park

Jurassic Park features 7 very different dinosaurs throughout the film, Tyrannosaurus, Triceratops, Velociraptor, Brachiosaurus, Dilophosaurus, Gallimimus, and Parasaurolophus. Each animal being significantly different from the other.

What most of the animals have in common is having themselves or standin relatives (or generally standins) living in Hell Creek. For some, it's very obvious, for some, I have to take some very speculative leaps.

Homo sapiens -

No Homo sapiens in Hell Creek! I'm the reference here so, yeah. No humans. It would've been funny to include Purgatorius here but humans weren't cloned for Jurassic Park. Carry on.

Tyrannosaurus -

Tyrannosaurus rex is known from all across western North America, ranging from the south to north. It's range is especially large, and its most well known locality is Hell Creek.

The Tyrannosaurus specimen used was AMNH 5027, the same specimen Jurassic Park used for both its Tyrannosaurus design and its logo. With the in-film size being roughly around 4 meters tall and fairly large, it only somewhat outsizes the actual AMNH 5027 specimen, where the individual is rather 3.6 meters tall and 11.5 meters long.

Triceratops -

Triceratops is a very well known ceratopsian and is prominent across North America, but especially within Hell Creek. The species T. prorsus was intentionally chosen to have an emphasis on the nasal horn. The actual species basis of the film is not stated, but some can assume T. horridus was used only because of it being the type species.

Velociraptor (as Dakotaraptor) -

Dakotaraptor is a large dromaeosaur known from Hell Creek. A lot of its anatomy is highly controversial with it being a potential chimera (beyond the obvious confirmed for the mixed-in turtle material). Because of it, many things cannot be reliably inferred for how it looked and behaved. Some speculation of taking the leg and arm material seriously leads it to be a fairly tall and cursorial-built theropod, adapted for high speeds. The validity of this though is up in the air until more specimens are gathered.

Dakotaraptor was chosen as the standin for Velociraptor mongoliensis due to Jurassic Parks' interpretation of it being a human-height sprinter-type animal found within North America, similar to what potentially Dakotaraptor would've looked somewhat like and behaved.

Brachiosaurus (as Alamosaurus) -

Alamosaurus is a titanosaur that roamed across the North American Ojo Alamo Formation and some nearby locales. Its position in being a Hell Creek sauropod is disputed, with there being a megafaunal barrier between North-South, preventing sauropods like Alamosaurus venturing any further north into Hell Creek. Although some speculation of it venturing in occasionally at some point in history is somewhat likely.

Alamosaurus was chosen as the Brachiosaurus standin only due to it being the nearest North American sauropod to being a Hell Creek sauropod. Brachiosaurids died off in the middle Cretaceous as sauropods generally leaned to extremes of small or large.

Dilophosaurus (as Anzu) -

The biggest reach of this post is Dilophosaurus, since Dilophosaurus and its closest relatives died off in the early-middle Jurassic due to them being an intermediate tetanuran, rather than being part of a surviving lineage.

Anzu fills in the role of a fairly nimble yet taller-than-Dakotaraptor theropod, with a prominent facial crest and potentially predatory diet. Ironically, Anzu is known from smaller specimens and is often undersized, with there being larger specimens out there implying a near 3-metre height.

Gallimimus (as Struthiomimus) -

Struthiomimus is an orninthomimid that lived across North America, often alongside other species of itself and Orninthomimus. It is the largest of the two known orninthomimids in Hell Creek.

Like Gallimimus, Struthiomimus is a highly speedy and sizeable theropod that is a very close relative.

Parasaurolophus (as Lambeosaurinae indet.) -

While Hell Creek has Edmontosaurus annectens, potential unnamed and unpublished material exists that may likely be a Lambeosaurine, adding to the roster of Hell Creek ornithopods. Parasaurolophus itself is a Lambeosaurine and lived in other nearby formations, although earlier in time. The possibility of Parasaurolophus living to end-Maastrichtian in Hell Creek is fairly low but not impossible. Though compared to Alamosaurus, it seems less likely to happen. A safer estimate (and something that would help publicize the idea) would be using the Lambeosaurine indet. as reference.

The Lambeosaurine itself is referenced from Hypacrosaurus and Magnapaulia, two nearby lambeosaurines from very similar timeperiods too. Some adjusted anatomy was used to make it stand out more, as we do not have much of this specimen.

Thank you for reading this very nerdy paleo-blog that helps somewhat justify my chart. Science will change, so the possibilities of this blog changing too (and the artwork) is likely, or just a republished rewritten version. We'll see!!!

Thank you, - Jennifer

*raises hand* i have no idea what Hell Creak is. tell me more

Hell Creek is a fossil-heavy rock formation located in Montana and North Dakota! It's one of the most complete fossil sites we have of the Mezosoic (along with other standouts like the Morrison and Kem-Kem). Hell Creek gets a few extra cool points for a handful of reasons:

It has a whole host of big name dinosaurs: T.rex, Triceratops, Ankylosaurus, Pachycephalosaurus, Edmontosaurus, and even a large raptor that's a real-life Jurassic Park 'Raptors' (the book and film used oversized Deinonychus, but Dakotaraptor is actually of comparable size. Potentially. I love the species and what it'd mean for the ecosystem, but I don't trust DePalma as far as I can throw him. He accidentally included turtle remains in the holotype, which... come on, man). Another cool big name potentially associated with the formation, but not a dinosaur, is a large Mosasaur species (think a giant marine monitor lizard) that was recently found to exist off the coast, as well as the (potentially) largest creature to ever fly, Quetzalcoatlus (I have no way to describe this, search it up, it's terrifying and weird).

Actually? No. You deserve to see what a Quetz would look like.

(Photo and model credit @bluerhinostudio. Seriously, they're so lifelike.)

Hell Creek's fossils were deposited at the very tail end of the reign of dinosaurs, so you get a look at their last glory days + a good handful of million years prior. Actually, the boundary layer - the actual moment the apocalypse became real and quartz was shocked by the Chixclub impact - is present! There's another site that seems to contain the actual aftermath, with molten glass raining into the mud and debris of animals caught in tsunamis thrown together (though some elements of the site are debated, because DePalma is sketchy as hell and reported different findings to the media vs his publications).

(Credit conveniently included in the image, nice.)

We have SO much information about it! Remains of everything from megafauna and their interactions - herbivores that have healed bitemarks from T.rex, facial bitemarks between T.rexes - to the minute. Pollen and seeds from a host of plants; insects trapped in amber; tiny amphibians, and sharks. The list of species on the Wikipedia articles are absolutely insane - it's so complex and detailed.

There's also a video game in slow, slow development depicting this formation, Saurian - last I heard it's grinded to almost a standstill, and IIRC there is ~tea~ in the paleo community about it, but it was fun following the development for a few years. The concept art is also gorgeous, and you really get a feel for just how much material they have to work with to make this as accurate as possible!

TLDR, Hell Creek is fascinating - though there are plenty of other cool formations worth poking at, too! The Kem Kem Group, Dinosaur Park, Candeleros, Morrison, Jiufotang and Nemegt Formations are all favorites <3

#ask #paleoblr #hell creek formation #I got to work on some Dinosaur Park fossils right before the pandemic and ALMOST got to go on a dig there. will forever treasure the memori #memories*#yes i found a dromaeosaurid*-ish tooth in the microfossils i was cleaning and cried about it so WHAT #anyways enough about that.
