Collected from the famous Hell Creek Formation of Northwestern U.S.A., this is a group of TWELVE fossil bone piece from the head frill of a Triceratops horned dinosaur. Each piece was cleaned and conserved in our lab to reveal all the unique surface detail and anatomy that is only found on genuine frill pieces. Each piece shows the unmistakable furrows and patterns seen on the facing surface of the head frill of a Triceratops skull. There are some great pieces in this group including outer edge pieces.
Along with the horns, the head frill is the most unique bone separating horned dinosaurs such as Triceratops, from all the other types, making this a fascinating and important fossil for any dinosaur bone collection.
Triceratops is the most famous of the great horned dinosaurs. This plant-eating group has been found in the fossil record in greater abundance than all the other varieties. A full grown Triceratops is estimated to have weighed 11 tons, heavier than a modern African bull elephant. Its skull was 6.5 feet long with a pair of brow horns that exceeded 3 feet in length.
