Academy" of author J. K. Rowling. This new species looks like the

skull we are featuring is a new one. It contains the lower jaws and
predentary, not present in the type specimen. This specimen (CKP-STD06)
was crushed, but is still a very exciting specimen. The entire skull
was covered in a hard iron rich matrix that took hundreds of hours to
prepare. With the popularity of the "Harry Potter" books, this is
a great way to introduce another generation to dinosaurs and our earths
The replica comes in 3 sections, the main head section and the two
horn cores, since they were not attached to the skull any more. All
parts of the skull are cast in a plastic resin, making them extremely
tough. They are painted to match the original patina of the fossil. The
detail of the teeth come out great in the replica. The horn cores are
similar, but the left horn core has 3 large horns coming out and the
right has only one.
Dimensions: The main skull section is about 20" long. The horn
measure about 8" long each.

The replica was created by molding the original fossil in 4 sections.
The two horn cores were not directly attached to the skull due to the
crushing. It is amazing that they survived at all when you look how
crushed the skull is. The skull was then divided into a main section
containing everything below the orbit and up to the snout, and the
elements above the orbit. Once poured, the two skull sections are
re-attached, but the horn cores remain separate.

the skull. This is the best side, showing a decent profile. The jugal
has a really nice horn (osteoderm). You can see that all of the snout
had become dissarticulated and piled up. It looks like all of the
elements of the snout and nasal are present, including the pre maxilla
and predentary! Image B

really see how crushed the skull is.
This replica will make a great addition to any Late Cretaceous
collection. It is small and looks very interesting. Katie Busch is
working on drawing of what the skull might have looked like before it
was crushed to help viewers to better understand what they are seeing.
Original Fossil: (CKP-STD06)
The original fossil for this replica was collected on private land in
North Eastern Montana. It comes from the upper Hell Creek Formation.
The fossil was crushed, but contained the dentary area which was not
present on the previous specimen. The replica is an exact copy of the
original fossil in its original condition. This is the first Dracorex
skull available to be purchased. The original fossil is currently being
prepared further to separate the individual skull elements.
Preparation & Casting Process
-- The preparation and casting was conducted by CK Preparations.
Preparation Images -- Below are some images of the skull during the
During the preparation, a tooth from the front of the dentary was
exposed! The tooth has the appearance of being serrated. This cannot be
seen in this replica but may be available at a later date.
Images above are of the left dentary tooth with what appears to be
serrations. Further preparation will be conducted to learn more.

has a similar tooth pattern.
