Prince Creek + Cantwell by Paleop Prince Creek + Cantwell by Paleop
Prince Creek, the anomaly of the Mesozoic. How dare it defy Bergmann's rule so much so. The anomaly be that the creatures are smaller than their southern relatives.  Since Prince creek taxa are generally extremely fragmentary and since there is little data, there is a possibility the taxa are not smaller than their southern relatives. Ugrunaaluk  is only known from juveniles. Nanuqsaurus is only known from teeth and partial jaw bones. Troodon from Prince creek dwarf their southern relatives.
If only the formation wasn't so fragmentary.

Close to Prince Creek is the Cantwell formation of Alaska. The formation has even less known material. Notable finds being parksosaurus fossils and a Therizinosaur track from an animal identical to Nothronychus in size.

The intention with this chart was to make a WWD style chart, where I showed off a select few animals. I was going to leave out Parksosaurus, Troodon, and Alaskacephale.  I decided the night before release to do parksosaurus. I will eventually update the chart with Troodon and Alaskacephale.

I have been wanting to do this formation for a while. I hope you all have enjoyed this chart

If memory serves me well, a short trackway from an Azdarchid was found in Prince creek, as well as Alaskacephale.

What if Pachyrhinosaurus got smaller due to competition from dinosaurs like Triceratops and Torosaurus so it got smaller to fill a different niche

The thing is it really didn't get smaller.

Even then, it lived in Alaska while trike lived in Montana.

I have been told that ''Not all of the animals in Hell Creek preserved as fossils. If you time traveled back in time to Hell Creek, it's very likely it would be as diverse if not more diverse than Kenya''

Which does not equivalate to pachyrhinosaurs living there.

Pachy is way too far north

I am nowhere near being a biologist so there's multiple grains of salt to be taken with this thought... But I thought of this thing one day. About the sizes of these dinosaurs. 

Isn't it theorized that all the larger dinosaurs weren't entirely warm-blooded but like, only partially so? So unlike the warm-blooded mammals we know today, they'd be somewhere in between being warm-blooded and cold-blooded. And we know that cold-blooded creatures shrink in size the colder the climate gets. What if such huge creatures as ceratopsians, tyrannosaurs, hadrosaurs and therizinosaurs weren't entirely warm-blooded so they had to shrink in size too to adapt to the colder climate? (Despite not being cold-blooded either, but still more cold-blooded than a truly warm-blooded animal) And unlike the big guys, Troodon would've been entirely warm-blooded, and just like modern warm-blooded animals, it grew larger in colder climates.

Like, to me this makes sense. I haven't seen it suggested anywhere before so idk how valid is it.

Also are the pachyrhinosaurus and the Ugrunaaluk in this drawing meant to be feathered?

1. mesothermy was debunked from what I remember.

2. looking at the animals southern relatives again, I doubt they were smaller.
Compare Nanuqsaurus and lythronax for instance.

pachyrhino and ugrunaluuk are not feathered

Thanks for clearing up. :D Good to know. See this is why I  added the reminder about the grain of salt. Haha. I knew I could turn out to be extremely wrong, and I did.

And yeah. As you said in the description as well as in your reply, kinda unlikely they even were so super small after all.

Is it possible that the dinosaurs shrank to make up for less food in the colder environment? (Similar to the phenomena of island dwarfism.)

possible, but considering how fragmentary the formation is, for all we know the species may not even be dwarves

Regarding the Alaskan therizinosaurs, are there actual fossil remains of it or is it just known from alledged tracks, like I heard somewhere before?

Nanuqsaurus almost looks...normal-sized in comparison to its contemporaries. Especially when you...have such a tiny Pachy in there. That's puny compared to P.canadensis

I think it's possible that the species were capable of growing o the same size as their southern relatives, if not the same size.

Cool colour pattern on the Dromaeosaurid. Does it have a naked vulture neck or is that just a pattern on the feathers?

most certainty. there were ankylosaurs from Antarctica (don't know if it was warmer or colder). Not to mention oviraptorosaurs are the bane of my existence ...I mean... cover the rest of the continent so why not?
