MASSIVE TRICERATOPS DINOSAUR FOSSIL VERTEBRA Hell Creek Formation, South Dakota, U.S.A. LATE CRETACEOUS PERIOD: 72 - 65 million years ago Collected
from the famous Hell Creek Formation of Northwestern U.S.A., this is a
massive partial thoracic vertebra of one of the most famous
dinosaurs, Triceratops horridus. The centrum is complete
with a portion of the dorsal processes including a complete and intact
neural canal that would have housed the spinal cord. This type of
vertebra would have had giant transverse and dorsal processes but
fortunately, the centrum and neural opening are present and offer an
affordable and impressive giant dinosaur vertebra. With the
processes, this specimen would sell for considerably more and likely
required restoration and fabrication. This specimen has a single
fracture that has been filled but it has
NO RESTORATION OR
FABRICATION.
Bone has been treated with a consolidant to strengthen its brittle
nature of preservation and make it safe to handle. Excellent preservation
detail on the outside and because it is a partial, you can see wonderful
internal pore structure to the bone. An excellent and very
affordable massive dinosaur vertebra in natural form. Horned ceratopians were extravagantly well-armored in their head region. Their skulls were heavy and armed with long, pointed horns. Extending off to the rear was a great sheet of heavy bone called the "frill". On some horned ceratopians, this was a solid sheet and likely served as a shield to protect the neck and even shoulders. On other types, the frill was an open framework of bone that was covered with skin, possibly acting as a heat shield or for social display. The edge of the frill on most horned ceratopians was armored with blunt, triangular spikes called epoccipitals . 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.
