TOROSAURUS FRILL SECTION WITH INTACT EDGE - 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 an
excellent frill section with original edge from the skull of a
Torosaurus, one of the largest of the horned dinosaurs. Unlike
many inferior frill fragments offered on the market, this is a complete,
unbroken portion of the finest preservation. Most important, it
includes a good portion of the original actual edge of the frill.
Because the edge is present, we can attribute this to Torosaurus which
did not have the same edge style of frill found on Triceratops.
This specimen was also found in association with other Torosaurus
remains on the site where it was collected. The surface detail,
color and density of this bone makes it an impressive and educational
display dinosaur fossil from the U.S.A..
For its astonishing
array of dangerous and large prehistoric predator fossils, no place has
captured more attention or has been featured on television more than
Hell Creek! Hell Creek is most famous for being the home of T.
rex!
One of the largest of these magnificent dinosaurs, the Torosaurus, did not have any epoccipitals on its frill edge but rather a smooth, slightly wavy surface. Perhaps the extra protection wasn't needed - the sheer massive size of this 25 foot creature might have been enough to make any other dinosaur think twice before starting a fight. EXCELLENT CHANCE TO ACQUIRE AN INTACT TOP GRADE FRILL PIECE FROM THIS FAMOUS DINOSAUR! 4.2" x 2.75" SOLD DB19-001 Actual Item - One Only |

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 .
