A Top Quality, Triceratops horridus brow horn from the late Cretaceous of northern North America. A May Fossil of the Month. Triceratops was a large ceratopsian dinosaur found in the Hell Creek Formation. This is a special horn with exceptional detail preserved and excellent color & natural patina. Fantastic surface articualtion. You can see all of the natural blood grooves around the surface of the horn. Plus this horn includes most of the orbital which is quite rare - a very complete specimen. The preparation of the horn was fairly basic and simple - some minor crack fill and approximately 1" of the tip end was restored which is very minimal restoration for a horn. This is not a horn that is 20 - 30% or more putty which you most often see. It comes with a custom steel stand as shown. A fantastic fossil overall for display. Legally collected on private land in the Hell Creek Fm., Butte Co., So. Dakota . Authenticity guaranteed. Certification of Authentication provided. Museum quality.
