Triceratops Horn and Frank Bliss
Happy New Years Day. I don’t take many Selfies. Maybe 5 or 6 a year. I just thought I’d be a scale for this brow horn from a rather large Triceratops horridus. Triceratops is the Wyoming State fossil but I bet a few more have been found in Montana. This one was pretty much right on the border give or take a few hundred feet.
Obviously the horn is missing the tip with was either “broomed” prior to the animals death or damaged during river transport. The Hell Creek/Lance formation covers our ranch entirely. Unfortunately for the fossil collector in me, most of that is covered by grass. The initial discovery fossil from the site this horn came from was literally sitting in the grass. Located on a shallow hillside, this site has given me over 30 Triceratops Horns, dozens of teeth, toes, claws, spines, scutes and other wise a pile of pretty well preserved dinosaurian bones.
Take my work on this being a horn, somebody out there will think it’s a limb bone missing the condyle end. Nope. It’s a horn. I’ve collected over a dozen just like it. It’s the 3-D nature of the fossil that gives it away. Horns have very characteristic surfaces and this one has veinous grooves with the proper interior of a horn. Shape is Seldom the defining characteristic of a fossil. There are many rocks that look like fossils (pseudofossils) but aren’t. This is a 66 million year old horn from a big Tric. I also have over a dozen nose horns. Thus naming my bone quarry the “Horn Sieve Site”.
Location: Bliss Dinosaur Ranch, Wyoming/Montana borderlands.
