Best Animals from the Hell Creek FormationThe Hell Creek Formation is a dig-site location located in Montana, North and South Dakota and Wyoming in the United States. The rocks found on Hell Creek date back to 66 million years during the end of the Cretaceous Period and is one of the most intensely studied and well-known dig sites in the world, with fauna such as Tyrannosaurus and Triceratops amongst the numerous fossil records found within the site.
Aside from dinosaurs, there was a plentiful amount of animals found within the site, such as mammals, reptiles, birds and many others. Which creature from the site stood out the most for you?
To find more animals from the Hell Creek Formation, you can use good articles featuring fauna such as Wikipedia or you can research an upcoming (when this page was being made) dinosaur game "Saurian".
The Top Ten
A fan favorite for many, Triceratops remains is the most common in the formation. Alongside T. rex, a lot has been seen and learned upon from this dinosaur, such as living in herds and age and possibly sexual dimorphism.
Aside from being the most well-known dinosaur (And my all-time favorite animal), Tyrannosaurus remains and research from the Hell Creek have been massive, such as the remains of Sue (The largest Tyrannosaurus remains discovered yet) having been found there and evidence of living in groups and even cannibalism. Surprisingly, it is also the second most common dinosaur found in Hell Creek.
My favorite plant-eating dinosaur, but the reason why Triceratops is higher is because not much has been found from Ankylosaurus. It looks badass and unique that's for sure, but we have more of that evidence from Euplocephalus (An earlier ankylosaurid millions of years earlier) as well :/. I still live this dinosaur, though...
I am so happy considering there is actually a decent sized raptor in Hell Creek and it's even feathered to top it off :). It could have provided competition against the juvenile and sub-adult T. rexes for food and territory.
I love hadrosaurs and Edmontosaurus is definitely the poster boy when it comes to the ones without a crest. Despite not looking as impressive, it's still a pretty impressive dinosaur and one of the most well-preserved remains of a dinosaur was of an Edmontosaurus in Hell Creek. It was called the "Dinosaur Mummy due to how well-preserved it was.
Azhdarchidae remains have been found in Hell Creek. While they may not be of Quetzalcoatlus, the possibility of this pterosaur living in Hell Creek is actually quite likely as they would often come down to land to eat even small dinosaurs or remains of larger ones.
A proper Oviraptorid in the Hell Creek makes me smile. It's surprising how much diversity the formation has. Though there may be second, much larger one in the area, but the only evidence of such comes from footprints only :/.
The first raptor to have enough fossil evidence to be formally classified in Hell Creek. Not as impressive as Dakotaraptor, but its discovery was important nonetheless.
The most well-known bonehead. Despite this, the animal is actually quite rare to find in fact. However, Pachycephalosaurus itself is a popular dinosaur and its discovery is certainly important.
A marsupial mammal. Its survival is the reason why we have Kangaroos and other living marsupials so remember that.
