#ceratopsipes

Ceratopsian tracks are actually fairly rare in the fossil record, though this was an amazingly diverse group of animals as indicated by skeletons alone. Tracks, however, have been found in the Hell Creek formation, and were about 2 feet long and once again the best information I could find out about it came from a fossil buying website. If these tracks are undistorted, they would come from an unusually large ceratopsian; even bigger than Triceratops, which means - as I’m sure you can imagine - most of the sites talking about it are Awesomebro sites discussing how this ceratopisan may have fought against T. rex because it was so huge. 

Sigh. 

(Awesomebro: someone who values awesomeness over accuracy. Typically does not like feathers, is more concerned with which dinosaur could beat another in a fight and which predators were the “best” even though that’s an evolutionarily incorrect concept, and just in general treats dinosaurs as monsters rather than real animals. The bane of my existence, well, one of the banes.)
