Incisivosaurus/Haikouichthys
Denversaurus/Chasmataspis
Though they prefer the drier upland areas, Ankylosaurus and Denversaurus occasionally wander into the wetter lowland floodplains that make up much of the Hell Creek environment. They seem particularly fond of wallowing in mudholes during the hot summer months.

Denversaurus by Jack Wood.
Though one might be forgiven for expecting such heavily armored animals to be more aggressive, these beasts are surprisingly tolerant. They have been observed allowing smaller theropods such as Acheroraptor and Pectinodon to snatch up any prey disturbed by their foraging and even letting them hop up to hitch a ride on their armored backs, and on several occasions colonists have seen them being cleaned of parasites by the alvarezsaur Trierarchuncus. They even seem to tolerate the presence of Nanotyrannus lancensis, provided they don't get any big ideas, though the larger N. lethaeus, as well as T. rex, tend to get a far more hostile treatment.
This is Edmontonia and Daspletosaurus, but you get the idea. Art by Brian Franczak.
As far as dinosaurs go they seem to be pretty awful parents, leaving their poorly armored young to fend for themselves.
A dinosaur tooth of an ankylosaur, possibly Denversaurus schlessmani from the Hell Creek Formation in Baker, Fallon County, Montana, United States. Not being well versed in the identification of thyreophoran teeth, the bulbous base could also suggest the ankylosaurid, Ankylosaurus magniventris. Ankylosaurus teeth can be identified with a combination of a bulbous base and a prominent center ridge, the latter which is not present in this tooth. While I'm not sure about all tooth positions of Denversaurus, some nodosaurids could possibly have a bulbous base as well making identification difficult without the presence of a center ridge.

It's been a while since I've drawn any dinosaurs, hasn't it? Time to rectify that.
This is a small collection of animals from the Hell Creek formation, for the most part. A few of them are a bit iffy, like the alvarezsaur and the rhamphorhynchid. Come to think of it, I think the latter went extinct in the Jurassic. The reference used was Saurian's Field Guide to Hell Creek, but I wasn't aiming for the absolute most accurate. Just something to keep my hand in after a little dip.
From top to bottom using their heads: a juvenile Tyrannosaurus, Thescelosaurus, an ornithomimid, Acheroraptor, Didelphodon, Palaeosaniwa, Pachycephalosaurus, an alvarezsaur, Anzu, big ol' frog, Champsosaurus, Pectinodon, a bord, Triceratops, and Denversaurus.
Like the Underdark monsters, there's also a transparent version as a sort of coloring page, if you'd like here. Just make sure to tag me so I can see it!
