One of the best dinosaurs in documentaries

[@jonathankennedy1963]

Probably the best one. The narration of David Attenborough, the music of Hans Zimmer, the tech and direction of Jon Favreau, and the expertise of Darren Naish and a few other paleo people, this series is a masterpiece. The Morgan Freeman and the Stephen Fry ones were a disappointment, at least that's what I've heard.

This series must be released in stores

Oh god, please yes.

[@EGarrett01]

1:16 Their necks are enormous. I imagine Pachycephalosaurs would've had super strong necks too.

[@datuhuginn5079]

I was a butcher's nephew, the reason why sheep, goats, etc has thick necks is because there's bony extensions in the vertebrae for massive neck muscles to attach to, kinda similar to a Spinosaurus. I guess Pachies did not have that structure, but its not hard to speculate they might have thicker neck than shown here.

Beautiful colors

[@kevinnorwood8782]

Part of me is still skeptical that what Pachycephalosaurs did was “true” head-butting like bighorn sheep or musk ox. The problem that arises with head-butting on a regular basis is the danger of getting concussions. At the same time, however, concussions might not have been as huge an issue for Pachycephalosaurs as they would be for things like us humans because their brains are much smaller than ours (smaller brains are harder to injure). Still, when I first saw the skull of Dracorex and listed to Robert Bakker compare it to the flat head of a modern warthog, it led me to believe that what these dinosaurs were actually doing was more like head-shoving: placing their heads against each other and then shoving back and forth until one of them gets a headache and gives up. I recently asked a few paleontologists about this theory, and they said it has some merit, but that merit is geared more towards the flat-headed Pachycephalosaurs. They told me domed heads aren’t really designed for shoving contests because they could glance off each other, so they were probably doing something in-between, and they cited this show as the closest example of what they may have actually been doing in real life.

Interesting idea.

[@DracoYahinAlchedius]

Pachycephalosaurus and Ankylosaurus are two of my most favorite dinosaurs ever.

[@Dimitri.Schepens]

[@PikachuIno]

I personally think it's better than Stygi in Fallen Kingdom

[@jonathankennedy1963]

You'd be thrilled to know that Stygi is likely a juvenile or a baby stage of Pachycephalosaurus.

[@PikachuIno]

​​@@jonathankennedy1963 For me, Stygimoloch is a different species of this dinosaur A cousin from Pachycephalosaurus

[@thejensonater4492]

@@jonathankennedy1963 iirc the current consensus is that Stygimoloch is its own species (As in not a juvenile growth stage of Pachycephalosaurus wyomingensis), just one that happens to be extremely closely related to Pachycephalosaurus, like to the point that it's probably most likely Pachycephalosaurus spinifer. So you could just call it Pachycephalosaurus spinifer, but since that makes it it's own species anyway (at least a separate one to the "main" Pachycephalosaurus wyomingensis) then there's really no problem with calling it Stygimoloch which is a very cool name after all. It's somewhat similar to the Tyrannosaurus/Tarbosaurus situtation.

[@paleopal]

​@@thejensonater4492 Ehhhh... If I recall correctly both Stygimoloch and Dracorex were proven to have extreme levels of plasticity in their skull growth, a surefire indicator of a juvenile specimen. Drastic reduction of head spikes is also very prevalent in Marginacephalia as the keratin is reabsorbed back into the skull with age. I believe the consensus is that they are both juvenile animals of some species, but may or may not be Pachycephalosaurus wyomingensis. Update me if I'm outdated.

[@dweebteambuilderjones7627]

@@paleopal It's both. _Stygimoloch_ is only known from juvenile animals, but because the fossils were found in younger rocks than _P. wyomingensis_ was found in some scientists are reluctant to synonymize them all the way down to the species level and only synonymize them at the genus level (thus making an anagenetic _Pachycephalosaurus_ like how _Triceratops horridus_ evolved into _Triceratops prorsus_ ; the species in the genus are separated by time rather than place or niche). _Dracorex_ is regarded as a juvenile _P. wyomingensis_ without issue, though.
