The MANY Interpretations of Pachycephalosaurus!

[@uchuuseijin]

I'm really surprised you didn't mention Rampardos in the video game section

[@SoftwareLearningify]

True was gonna say

[@TESplayer8811]

Yeah😢

[@dlbaryonyx2468]

Dracorex's appearance in Primeval matches with the show's recurring theme of the some of the animals being the origin of several mythological creatures, in this case the episode featuring the dracorex has it appearing in medieval europe and being hunted by a knight both in the past and modern times

[@SmashBrosAssemble]

Well it was a one off line in series 1, then became a plot point in series 3.

[@TomasGomezGoitia]

Its just a dragon

[@MarkTheDilophosaurus281]

That thing looks like a cross with the monsters resurrected Spinosaurus

[@SmashBrosAssemble]

@@MarkTheDilophosaurus281 Well no id say their Spinosaurus (which is also awful) looked like the Monsters Resurrected Spinosaurus

[@siewpeisi9937]

It was so different I thought it was a new carnivore dinosaur

[@MarkTheDilophosaurus281]

Pachyce, pachy uh, Friar Tuck. That line is easily the best line in the franchise.😂

[@Meme-penguin69]

Pachys be like: im gonna headbutt ya im gonna headbutt ya

[@i.m.evilhomer5084]

6:09 For whatever reason, people seem to mistake the length of Pachycephalosaurus for its height. It might be an old mistake as there are sci-fi stories from the 1950s that depict Pachycephalosaurs as big as T. rex.

This vid unlocked a core memory for me with that Pachy toy. Holy moly...

[@eagc7]

If we count Stygimoloch as a young Pachy, then there is also its appearance in the newest Transformers cartoon Earthspark, where one of the main characers called Jawbreaker transforms into a robotized Stygimoloch

[@DeeRose54]

Primal Carnage: Extinction has a neat one. It’s portrayed as omnivorous which is pretty unique.

[@izael7000]

3:02 Some studies also indicate that the genus Stygimoloch is valid but one of the species would not be from this genus, but from the genus Pachycephalosaurus.

[@christianmanka3884]

The Cranidos and Rampardos pokemon is also pachys.

[@PurpleTurtle69-w8e]

yes, very true

My all time favorite dinosaur since land before time and seeing Frier Tuck in JP2 in theaters another amazing video bud

[@adnanpulic7611]

13:16 the "young guy" is actually a stigymoloch,we also see adults in the show and they have the same colours

[@Quazzy23]

You forgot the documentary "Dinosaurs decoded" where the idea mentioned that pachyephalosaurus grew out of dracorex

[@neonskye740]

Fun fact: Apparently Primeval's Dracorex is called Princess

[@SmashBrosAssemble]

It is, it’s called Princess because the whole thing with it is you think it’s the monster but it’s actually the damsel in distress.

[@TomasGomezGoitia]

​@@SmashBrosAssembleme too

[@GeteMachine]

I remember seeing an episode of Bonehead Detectives (good show that I think held up), and it was argued that Pachicelalosarus likely didn't ram into each other from a distance like Bighorn Sheep, because of the head wasn't a too angled to guarantee direct hits without slipping off each other. So my guess, is that they likely hit each other at close range or shoving, and knocking each other like giraffes.

[@andrewmalinowski6673]

If this is the group I'm thinking of, they said the kinetic force would have caused concussions for the dinosaurs but likely made glancing blows against their rivals' skull

[@dont-hurt-me2519]

At 6:58 & the design of the Cephalozord at 1:50, I remember a study a while back (can remember any specifics) that theorized that Pachycephalosaurs might have fought each other/defended themselves in a similar manner to Kangaroos; by scratching attackers with their hand claws & kicking them with their feet

[@albatross4920]

Me everytime I see stygimoloch: "It's still real to me dammit!!" 😢💔

[@MarkTheDilophosaurus281]

Me too

[@tastelesspotato4151]

stygimoloch is my fav dino so im very happy you included it

[@cryoking5025]

It not valid, Stygimoloch and dracorex are just juvenile pachys(however, it can still be your favorite, just wanted to let you know

[@CaptainCretaceous91]

FYI, Dinosaurs anchorman Howard Handupme is also a pachy.

[@256NatLiz]

The differences in head domes and whether that is an indication of maturation changes is brought up in the Dinosaur Sanctuary manga. Real cool to keep that conversation going!!

[@andrewmalinowski6673]

In his TED Talk about "Shape-shifting Dinosaurs" Dr. Horner described the Dracorex as being a pre-75% growth stage Pachychephalsosaurus and the horns being "resorbed in the skull" as it matured into a Stygimoloch as the domed skull developed/formed

Wtf

[@dont-hurt-me2519]

Here's a few interpretations of Pachycephalosaurus, Stygimoloch & Dracorex that I know of: -Dink the Little Dinosaur (Pachycephalosaurus was featured in the episode, "The Reluctant Head Banger") -Dino Riders franchise (Pachycephalosaurus appeared as both a toy & as one of the many dinosaurs allied with the Valorians in the tie-in TV Show) -Animal Crossing franchise (From "Wild World" to it's most recent game, "New Horizons", the skeleton of Pachycephalosaurus is one of the many fossils the player can donate to the Museum) -Dinotopia franchise (Both Pachycephalosaurus & Stygimoloch make a few appearances throughout the books. Pachycephalosaurus also made a brief appearance in "Quest for the Ruby Sunstone") -Dinosaurs Decoded (All three dinosaurs are featured in this National Geographic program; which debates on whether the three are actually the same animal. The model for the Pachycephalosaurus is also the same model from the 2014 film; Dinosaur Island) -Pokémon franchise (Cranidos & its' evolution; Rampardos, are based on Pachycephalosaurus) -Dino Island PC Game (This PC Game from the 2002 has Pachycephalosaurus as one of the many adoptable dinosaurs the player can place in their park) -Warpath: Jurassic Park (You already mentioned how Pachycephalosaurus is a playable dinosaur in the game but Stygimoloch is another playable dinosaur in the game as well) -Dinosaur Empire! by Abby Howard (Dracorex, Stygimoloch & Pachycephalosaurus are featured in this graphic novel towards the end) -Jurassic World (Pachycephalosaurus makes a brief appearance in the film; much bigger than its' previous appearance in The Lost World) -Rourke Dinosaur Library (One of the books focuses on Pachycephalosaurus) -Dinosapien (The Diggers, one of the villains for the TV Show, are primarily based on Pachycephalosaurus but also have armored features of Ankylosaurus) -The Wildlife Park franchise (Pachycephalosaurus is an adoptable animal in the "Dino World" expansion for Wildlife Park 2 & "Dino Invasion" expansion for Wildlife Park 3) -Safari Ltd, Schleich, Papo, Battat Terra, etc. (These toy companies have made figurines of at least one of the three dinosaurs) -Dinosaucers (The character, Bonehead, is a Pachycephalosaurus) -Dinosaurs TV Show (While some sources claim that the character, Spike, might be a Polacanthus; IMHO I think he resembles a Pachycephalosaurus. Albeit, a bit more stylized)

[@siewpeisi9937]

Dexus dinosaur has pachycepholosaurus and stigymoloch or something and pachycepholosaurus appears in their newest game as a enemy

[@Firestar-TV]

lol the Expansion for Wildlife Park 2 was weird. Claiming to have used the newest Research, despite the Raptors being bald and probably other Inconsistencies (has been Years since I've played it) while also having a Campaign that doesn't really make Sense. The worst though are the Expansions for Wildlife Park 3, just 1:1 transfering Stuff from Wildlife Park 2 + only releasing them on Steam, meaning many People would've needed to buy a Game they already own, again 🤦🏻‍♂️

[@F.H.W]

Definitely recommend checking out The Isle (EVRIMA's) Pachy as it has seamless growth that transitions as it gets older through the Dracorex and Stiggymoloch morphs. With its sounds and customisable skin patterns changing too.

[@SpaceSquid-wk2dn]

this lil guy has recently become one of my top 3 favorite dinosaurs now i give all that credit to Path of titans pachycephalosaurus which i adore an made me love this animal so much. what an underdog of an animal!

[@marioabel]

You missed the one from Dino Dana the movie. They even talk about the idea of Stigimoloch and Drakorex beeing juveniles Pachys

[@SmashBrosAssemble]

So of course we’re including Pachycephalosaurs itself, Stygimoloch & Dracorex. The best has to Prehistoric Planets Pachycephalosaurs in spite of it not having cheeks which they would have, it’s a Marginocephalian after all. The worst undoubtedly is Primeval’s Dracorex/Pachycephalosaurus, which some people try & defend that design & I think they’re on crack, cause even I, a defender of Primeval’s creature designs, will not defend that one.

[@KaiLutt]

New Worlds pachy is boring and shit but primevals dracorex fits the theme of some species inspiring real-life myths and legends (similar to the one croc thing in the museum episode). It also just looks really cool.

[@SmashBrosAssemble]

@@KaiLutt I get what they were doing, but I hate it, I think it’s an ugly over designed mess that bares no semblance to a Pachycephalosaur.

[@cezannejimenez7164]

14:30-17:30 Speaking of quills & colorful domes, in Prehistoric Planet 2, the male Prenocephale (which are related to Pachycephalosaurus) have bright blue domes & quills along base of their tail.

I’ve always loved the Primeval Draco design. It’s so wacky but I love the episode with the knight and the Dracorex. It goes a bit far but so do MANY of Primeval designs. I love it! Wasn’t as big of a fan of PE:NW Pachy design.

[@Katarn84]

As usual, I come to enlighten on Transformers dinosaurs. In Beast Wars Neo had a Pachycephaalosaurus in the Predacons ranks, Hardhead (duh...), the character and the toy were a heavy remold od the original Velociraptor mold of Beast Wars Dinobot. In the Fossilizer subline in the War for Cybertron: Kingdom, there is a little guy (two considering his repaint) that transforms in a Dracorex fossil skeleton, Vertebreak (and the repaint Dracodon).

[@prettystupid3509]

there's an older mmo rpg browser game i used to play called Dino Storm that has a few dinosaurs as well, but ones that you've probably already covered (like triceratops, pachy, brachi and of course the rex) still wanted to mention it though

I remember I had the Pachy little toy from The Lost World (stress on HAD, my father threw in the trash almost all y toys when I was fourteen). It did look like a Stigy or a Dracorex antelitteram. I think it was a juvenile and it had horns and a small or missing dome, the head was quite flat.

With learning that the Wikipedia pages of Stygimoloch and Dracorex gone since they're identified as juvenile Pachys, I feel like the Jurassic franchise needs to redesign the Pachy to look more like it grew from the Stygy. I prefer the Stygimoloch.

[@eondude2675]

I know you don't include every single interpretation since I would literally take forever and unnecessary since most designs look similar to each other but I think you should have included the dino Dana the movie interpretation of the Pachycephalosaurus since I think it has a really interesting design and also it has the stygimoloch and dracorex in the film as well

[@shawnbrunner4097]

Would this includes Stygimoloch and "Dracorex"? Anyways, did you know that Pachycephalosaurus was considered the most dangerous and predatory pachycephalosaurids ever known? Despite that they are complete vegetarians, but if you look closely to their mouths, that contains sharp, knife-like teeth that reminiscent to theropods, which the Pachycephalosaurus turns out it's an omnivore, remaining their vegetarian diet, they also had the meat diet, besides insects, are small dinosaurs of all ages, mammals, fish, young of middle-sized dinosaurs, eggs, birds, lizards, and carrion, and their sweet-tooth diet also contained honey and berries, that makes Pachycephalosaurus's diet more bear-like.

How does the discovery of varied diets in dinos like Pachycephalosaurus affect our understanding of their behavior and ecology? Do you think it changes how we interpret their interactions with other species in their environment?

There is a rather Obscure Anime called Dai Kyoryo Jidai Or The Age of Great Dinosaurs. About aliens sending three kids back in time and they are stalked by a T-Rex through time.

@@DinoGuy8 Wanna hear what they told me that made me never think the juvenile idea was correct again?

@@DinoGuy8Honestly Dracorex is the juvenile and I think Stygimoloch may have been older than Pachycephalosaurus. A study in 2021 says Stygi could be its own genus. It’s the first Pachycephalosaur I was ever introduced to. So Stygimoloch is its own genus

[@AncientWildTV]

@@MarkTheDilophosaurus281 Youre right. the relationships between Dracorex, Stygimoloch, and Pachycephalosaurus have been debated. Recent studies, including those from 2021, have indeed suggested that Stygimoloch might be distinct enough to warrant its own genus rather than just being a growth stage of Pachycephalosaurus.

[@clydetheguy.9082]

wheres prior extinction pachy...

[@daffierpython7755]

I personally think pachy stygi and dracorex are all seperate. Their spikes compared to the pachys small bumps around their dome heads just dont matchup. How a couple very large spikes recess intk the skull and become MANY very small bumps doesnt compute. Now if pachy had about the same amount of bumps as they have spikes, and the were in the same spots and the bumps had distance from one another then id think otherwise but atm i feel theyre all seperate

[@william3100]

At best, I think dracorex MIGHT be a juvenile but not of the species of pachycephalosaurus that we know now. I'm a supporter of the "stygimoloch is a separate species of pachycephalosaurus" camp. Maybe dracorex was a juvenile of that potential species?

[@daffierpython7755]

@@william3100 I would take dracorex and stygimoloch as the same but not pachys, but I don’t think dracorex would be a younger individual. Could moreso be male and female, females being stygimoloch the bigger one, and females being dracorex the smaller one. Mainly because it’s make sense for dracorex to have rough spikey heads to more easily attack other males, similarly to how deer evolved lots of sharp edges on their antlers, to better compete, while stygimoloch would also have the spikes either for threaten displays or for attacks but smoother heads due to being female

[@william3100]

@daffierpython7755 I mean, the bones of dracorex are immature and are much smaller than stygimoloch. Most male archosaurian reptiles aren't like that. Also, the head of stygimoloch is still tough and dome-like. It would've been used for intraspecific combat like pachycephalosaurus. It's also a better ramming weapon than a flat head with little spikes. I've also heard from a paleoartist on deviantart that the heads of pachycephalosaurus and others may not have been very smooth as commonly depicted and would still have tough scales on it. Maybe even bumby scales that almost resemble osteoderms in some way. Maybe the spikes on dracorex changed and shrank in terms of bone core and gave away to still being prominent in tough, keratinized, or cornified(I don't know which)scales for combat? I could be either very wrong or misremembering a couple of things, but maybe it was like that?

[@reptisaurusking8494]

I’m of the minority that Dracorex, Stygimoloch and Pachycephalosaurus are separate species entirely Also I remember a Pachy in Dino Fury that had a kangaroo gimmick

[@lordcooler8160]

It’s actually reasonable that Stygimoloch was a separate Pachy species relative to the type species because it’s found in more recent rocks. It’s still considered a subadult just that it doesn’t grow into P. wyomingensis rather P. spinifer. For Dracorex the overwhelming consensus is that it’s a juvenile Pachycephalosaurus though it’s unclear whether it’s the type species
