North America, late Cretaceous Period, ca. 68 to 66 million years ago. A collection of rib bone fragments from a triceratops (Triceratops horridus) that have fused together into a cluster during the fossilization process. These bones have acquired a deep umber coloration from the minerals and age. The first triceratops specimen was discovered just west of Denver, Colorado, in the town of Morrison, in 1887, by Arthur Lakes and named by Othniel Charles Marsh. These large horned animals were initially mistaken for a form of bison before they realized they represented a type of dinosaur known as a Ceratopsian. In life, these herbivores grew to over twenty feet long and could weigh over 10,000 pounds! Size: 27" L x 15" W x 5.5" H (68.6 cm x 38.1 cm x 14 cm)
Provenance: private Lakewood, Colorado, USA collection, acquired 2015; ex-private New York, New York, USA collection
