Welcome to Pioneer Fossils!
A photo Certificate of Authenticity from us at Pioneer Fossils will
accompany this specimen. Plus a free "floating" display stand.
Here is a superb rare genuine small Epoccipital bone section from a Triceratops,
from the late Cretaceous, as late as 66 million years ago, the end of the Reign
of Dinosaurs. It has been positively
identified as a Triceratops, as it was part of a dinosaur that was
identifiable, but too heavily eroded to recover much of the skeleton.
The Epoccipitals (no relationship with the Occipital bones) were triangule-shaped bones that fused with the frill as the triceratops matured. They are the distinctive triangle bones that stick out all around the frill on some Triceratops. There is study going on as to whether these would get smaller as the animal aged, or disappear completely.
Photo 4 shows various Triceratops with some arrows pointing to some of the eppocipitals on a juvenile.
It is small, and measures about 1.6" by 1.25" and weighs 28 grams.
It is from Hell Creek Formation near Sewell, South Dakota. An excellent addition to a Triceratops collection.
Triceratops is one of the most famous of all dinosaurs, with
its huge head, tough bony frill, and three sharp horns in the front. The movie,
Jurassic Park, features a sick Triceratops that Ellie cared for.
The largest Triceratops grew to over 28 feet in length, and
weighed up to 13 tons. It was, however, a plant-eater, with a beaked jaw and
hundreds of teeth (up to 800) packed closely together for chewing the
plants. There are two different
Triceratops: horridus and prorsus. The horridus are always found in ground
below the prorsus, so they are older. The horridus have a smaller nose horn and
larger beak than the prorsus.
A very interesting and authentic large fossilized piece of a
famous species of dinosaur.

This item, along with all

reach of children.

Seller's responsibility
ends at the US destination we ship it to. We are responsible for items going to
international destinations only until they reach the US eBay international
shipping center.
COMBINED SHIPPING: We make every effort to combine shipping
costs and we refund any overpayment back to you, on the same day we ship the
item. We have given hundreds of partial
refunds for combined shipping savings.
We will do our best to combine purchases to save shipping costs. In some
cases, that is easy, in some cases, not as much. Our items are of vastly different sizes and
weights, but we never use shipping as a profit center. We would rather refund the shipping
overpayment back to you.
We are happy to enclose a COA (Certificate of
Authenticity). Some words of caution about COA’s: Do not let them
become a substitute for learning about the specimens. We have been working with
fossils and minerals for many years, and we have seen hundreds of very
nice-looking COA’s, some that are wrong, mis-describing a specimen.
A COA should be specific
to one particular specimen, with a photo
of the exact item on it. At Pioneer
Fossils, our fossils and minerals come
with a COA, and each have a photo of the exact
item you just purchased. This assures that the COA can never be
transferred to a different specimen.
