Saurodon "Skull of a rare and exotic fish"
Cretaceous (83 m.y.o.)
Niobrara Formation
Smoky Hill Chalk
Gove County, Kansas, USA
Extremely rare and bizarre predatory fish skull from the Cretaceous of Kansas. The skull is in excellent condition and measures 19" long and 10" tall. The generous slab of matrix measures 31" x 14" x 1" thick. Unlike it's contemporary cousin, the swordfish Protsphyraena, Saurodon has an unusual predentary that is triangular and pointed. This bone was obviously used as an offensive weapon. Dozens of small teeth are present in the maxillary and the dentary. Bone texture is superb. Skull bones are three dimensional and have substantial relief from matrix. 100% ready for a wall mount. A rare discovery!

 Pteranodon
longiceps
"Complete pterosaur wing"
Cretaceous (83-88 m.y.o.)
Niobrara Formation
Smoky Hill Chalk

RARE wing from a Cretaceous pterosaur, on matrix, 71" long x

pterosaur of this size would have had an overall wing spread of
approximately 13 1/2 feet. To maintain strength and durability of
the specimen, it has been mounted on simulated matrix (3/4" thick);
however, the matrix surface is covered with a very natural-looking
actual chalk veneer. Specimen is very strong and durable and 100%
ready for a wall mount. Hanging hardware has been installed on the

Large, complete skeleton of a Cretaceous predator fish, measuring 6 feet (72") long, on matrix, 83" x 33". The skull is 100% complete, with substantial depth and relief. All four (4) jaws are present and contain 88 teeth (most in EXCELLENT condition)! The large cranial crest, which is characteristic of the Ichthyodectids, is well-defined and dimensional. The left upper jaw displays a healed injury (pathological). Skeleton consists of 90% real bone and weighs approximately 150 lbs. Complete skeletons of large fossil fish in the Niobrara are extremely rare due to the large number of sharks and other scavengers present in the prehistoric ocean. The Ichthyodectid genus includes another similar and well known Kansas fish, the Xiphactinus audax, which grew to lengths of up to 18 feet.
This exciting and striking display fossil is engineered for a wall-mount and is 100% ready for display! A custom wood crate is included for safe shipment to any address in the world!

 Platecarpus cf. planifrons
(possible new species)
“Mosasaur skull
with some post cranial elements”
Cretaceous (83 m.y.o.)
Niobrara Formation/Smoky Hill Chalk
Gove County, Kansas, USA
First time offering of an extremely rare species of Mosasaur.
The famous paleontologist, Professor Edward D. Cope, first described
this gracile species, Platecarpus planifrons, in 1875. Although
Mosasaurs are fairly common in the Cretaceous period throughout the
world (in the past two hundred years, literally thousands of
individual specimens have been discovered), only a handful of
Platecarpus planifrons discoveries have been reported.
One of the identifying features of this species is the long and
slender teeth, with pronounced faceted ridges on the enamel. It also
has fewer teeth per jaw than the more common variety, Platecarpus
coryphaeus.
This specimen consists of the skull (70-80% complete), the
atlas-axis and cervical vertebrae, plus approximately eight (8)
dorsal vertebrae and a few cervical ribs. Some of the remains have
been removed from matrix using the air-abrasive technique. Others,
including the jaws, have been surface prepared and left in their
original matrix.
Preservation and bone detail is exceptional! Muscle attachment
points, nerve and vein openings, plus numerous predatory shark tooth
marks, are all extremely well preserved.
This specimen is one of the best candidates for research that we
have seen in the Niobrara. Therefore, we are restricting the
purchase to an institution that will be a permanent repository for
the specimen, or to an individual willing to donate the specimen to
such an institution.
The purchaser will be supplied with a photographic record of the
excavation, exact stratigraphic data, GPS coordinates, and Section,
Township and Range. The specimen was collected on deeded, private
land with written landowner authorization.

 Xiphactinus
audax
Cretaceous (83-85 m.y.o.)
Niobrara Formation/Smoky Hill Chalk
Gove County, Kansas
GIGANTIC fish skull (profile) and post cranial bones from an
extinct predatory fish, on matrix, 42" x 27 1/2". Skull measures
35 1/2" long and 22" tall. Lower jaw measures 13 1/2" long.
Approximate weight is 75 pounds. Estimated length of entire fish
would have been approximately 14 feet. Skull is 3-dimensional and
has substantial depth and relief (lots of peaks, valleys and
ridges). There are a total of 33 REAL teeth. Largest tooth is 2
1/4"; two (2) other large teeth range from 2" long to 2 1/8" long.
ALL are in excellent condition! There are seven (7) large cervical
vertebrae. Cranial elements exhibit superb texture and detail.
Trauma in the posterior area of the skull (evidenced by
disarticulated vertebrae) indicates that sharks and other scavengers
most likely ate the body of the fish. Minimal restoration with only
minor cosmetic repairs! This is an exciting and striking display
fossil of the largest fish species (except sharks) that ever roamed
the prehistoric Cretaceous seaway! Specimen has mounting hardware
installed on the back side and is 100% ready for a wall mount.
UNIQUE exhibit and decorator fossil!

Smoky Hill Chalk
Gove County, Kansas, USA
Partial marine reptile skeleton; includes the complete skull,
all articulated cervical vertebrae (7), 12dorsal vertebrae, and 20
complete ribs. The specimen also includes one complete shoulder
girdle and 50% of the right front swimming paddle. Skull measures

embedded in areas of prior fleshy tissue, numerous shark tooth bite
marks on the ribs and scapula-coracoid and an area of preserved
stomach contents (fish bones and mosasaur tooth). Several of the
partial ribs have been bitten in half. Specimen also displays
several areas of soft-tissue preservation, including the cartilage
that attached the shoulder girdle to the skeleton and connected the
ribs at the sternum. Bone is in excellent condition with superb
detail! Estimated length of this marine reptile would have been
approximately 16-18 feet. Specimen is presented “as
discovered” in its natural chalk matrix; no restoration or
rearranging of the skeletal components! A very dynamic decorator or
