More dinos

[mascula-sappho]

If many species of bird (modern Dinosauria) exhibit homosexuality, than why on Earth would Mesozoic dinosaurs not? think about it.

A mated pair of female T. Rex that form a social group and hunt and live together.

a herd of Pachycephalosaurus where the two rival males end up mating.

A Sinosauropteryx that finds another female, mates with her, and then mates with a male and lays eggs.

(did I shamelessly use my favorite dinosaurs as examples? Yes. But hear me out)

Day 25: Pachycephalosaurus wyomingensis

#Archovember Day 25 - Pachycephalosaurus wyomingensis

I try to include a Pachycephalosaurid in every Archovember, but I have been dancing around drawing the Big One. Until now.

From Late Cretaceous North America, Pachycephalosaurus wyomingensis was a bipedal herbivore that may have also eaten insects and meat due to its bladelike front teeth. It is of course most well known for its extremely thick, domed skull. Initially, it was thought that these skull domes were used for intraspecies conflict, and that males would headbutt each other in a matter similar to bighorn sheep and musk oxen. However, this hypothesis is more recently up for debate. The rounded shape of the skull and the orientation of the cervical vertebrae seem unfit for the stress of direct head-butting. One study suggests that Pachycephalosaurs would use their skulls to strike rivals in the flank, as their broad torsos would have protected their vital organs. Even so, histological studies have shown that Pachycephalosaur domes were made of a unique fibrolamellar bone that would have been able to heal injuries relatively quickly. So head-on headbutting seems to still be a possibility.

Two other Pachycephalosaurids have been found in the Hell Creek Formation: Dracorex hogwartsia and Stygimoloch spinifer. These pachycephalosaurs were smaller and had flat skulls. But Dracorex and Stygimoloch have only been found as juveniles, and Pachycephalosaurus have only been found as adults. As they lived in the same time period and area, most paleontologists agree that Dracorex and Stygimoloch were different growth stages of Pachycephalosaurus, and that it would grow its domed skull as it matured. (Of note though is that all Stygimoloch specimens have been collected from the upper part of the Hell Creek Formation, and all Pachycephalosaurus’ were collected from the lower part. So Stygimoloch still may be it’s own species.)

Late Cretaceous North America was home to some of the most famous dinosaurs, so Pachycephalosaurus wyomingensis would have lived alongside many familiar faces. These include the hadrosaurid Edmontosaurus, ceratopsians like Triceratops, Torosaurus, Nedoceratops, Tatankaceratops, and Leptoceratops, ankylosaurians like Ankylosaurus, Denversaurus, and Edmontonia, the neoornithiscian Thescelosaurus, the dromaeosaurs Dakotaraptor and Acheroraptor, the ornithomimids Ornithomimus and Struthiomimus, the Caenagnathids Anzu and Leptorhynchos, and of course, the tyrannosaurid Tyrannosaurus rex. There were also many species of frogs, salamanders, fish, turtles, birds, mammals, at least two species of pterosaur, the choristoderan Champsosaurus, and crocodylomorphs like Borealosuchus and Brachychampsa.

A pachycephalosaurus skull pin that I sculpted

Fun fact: did you know that because of the amount of iron that is in the dirt where fossils are, fossils are actually a rusty brown color! Another fun fact: some paleontologists believe that the Stygimoloch might be a juvenile of the Pachycephalosaurus Wyomingensis. There are some theories that the other pachycephalosaurid, the Dracorex hogwartsia (which means "dragon king of Hogwarts") might be a female specimen of the P. Wyomingensis, but that's just speculation.

T.rex quarreling in the rain

67 million years ago as a storm quickly approaches a riverine forest in what is now the Hell Creek a formation of Montana, two Tyrannosaurus rex right over a Triceratops carcass while a lone Pachycephalosaurus wyomingensis watches from behind a fallen log.

I found this meme on Pinterest and I feel like many Pachycephalosaurus wyomingensis therians will appreciate it.

[cauldron-burn-and-fire-bubble]

dinosaur au. what else do you want me to say

for anyone who's interested the bachelor is Deinonychus antirrhopus, haruspex is Parasaurolophus walkeri, and changeling is Pachycephalosaurus wyomingensis

Pachycephalosaurus Duel

It’s the rut season for Pachycephalosaurus wyomingensis in Late Cretaceous North America around 66 million years ago, and one of the young rams is about to ram into his competitor’s flank in a duel to see who can win over the local ewes. It was once common to depict these dome-headed dinosaurs as butting heads like modern bighorn sheep, but ramming into each others’ sides seems at least as likely if not more so as I understand it.

GUYS GUYS GUYS

I AM SO PROUD OF THIS EDIT

child me would be so happy we still love pachycephalosaurus ❤️

also I use it as a stimboard so...

On a roll today, gonna tell you about one of my favourite dinosaurs and the reason why: Pachycephalosaurus wyomingensis!

Most people with even a passing knowledge of dinosaurs know that pachycephalosaurids are amongst the coolest dinos, but what makes P. wyomingensis so great to me is its name, which directly translates into "thickheaded beast from Wyoming"

THICKHEADED BEAST FROM WYOMING!!!!

It brings me so much joy to know that there is a dinosaur essentially named the "ugly dumbass from fucking Wyoming" because my god that is funny.

Dino Charge's dino selection realistically does not make sense. Only Tyrannosaurus rex, Triceratops prorsus, Ankylosaurus magniventris, and Pachycephalosaurus wyomingensis would have met. everything else was scattered all over the mesozoic. Parasaurolophus went extinct a few million years before Tyrannosaurus and friends showed up, Pteranodon went extinct a few million years before Parasaurolophus existed, Stegosaurus lived in the late jurassic, Plesiosaurus lived in the middle Jurassic, and Velociraptor and Titanosaurus lived on the other side of the world. The majority of the dinos lived in the cretaceous period, Stegosaurus and Plesiosaurus were outliers. Though, symbolically, the dinosaurs do make sense, Tyrannosaurus, Triceratops, Parasaurolophus, and Velociraptor all lived around the same time, like their rangers, Stegosaurus lived a SUPER LONG TIME before the aforementioned four dinosaurs, like Koda. Pteranodon is kinda in the middle chronologically, like Ivan. It all makes sense until Kendall, fuck you kendall messing up my coincidental symbolism, I'm switching plesiosaurus with elasmosaurus, a plesiosaur that lived in the late cretaceous and makes more fuckinig sense.

Titanosaurus, however, is the worst because it is an invalid genus and it would have never met any of the other rangers' dinosaurs due to being in cretaceous india.

Only Tyrannosaurus rex, Triceratops prorsus, Ankylosaurus magniventris, and Pachycephalosaurus wyomingensis would have met. everything else was scattered all over the mesozoic.

so only tyler/shelby and james/phillip could exist then huh

and yeah the symbolism makes sense if you look at it that way

the kyoryuger/dino charge writes rlly just put dino names in a bowl and pulled them out willy nilly huh 😭.
