Major Acquisition Fossils

Our policy has always been that any fossil vertebrate considered scientifically significant is reserved for acquisition by a pubic institution as part of a permanent collection. We also recognize that there is some room for interpretation of the term “scientifically significant” as a clear definition does not exist. In light of this fact, we restrict the availability of any skeleton having particularly unique characteristics to institutional buyers. Unless otherwise noted, purchase of any specimen includes scientific publishing rights, but TPI retains the commercial casting rights on all specimens sold.

Prices will vary based on the level of preparation and mounting required. Please contact us to discuss prices and options.



Edmontosaurus annectens "WXT" | 65-75% complete

Size: This specimen is an exceptionally large individual, and will measure 35 feet (10.7m) long, and 12 feet (3.66m) high at the hips.

Availability: 3-6 months from acquisition.

Locality: Hell Creek Formation of South Dakota. 66 million years old.

Description: Standing on two legs the head could rise to over 20 feet. Approximately 65-75% of the original skeleton is preserved, sans skull. The skull placed on the mounted specimen would be a composited cast at nearly 4 feet (1.3m) long. Skin impressions have been preserved on some bone and matrix surfaces suggesting this Edmontosaurus was partially mummified.

Comments: Skin impressions have been observed in a number of places on this partially mummified Edmontosaurus.

Sturdy field jackets were constructed to preserve articulation and soft tissues.

Bone preservation is excellent and many distal elements were recovered, including phalanges.

Most material is in field jackets. Preparation can begin immediately. Some skin impressions on several parts of the body are preserved with the fossil material.

Maiasaura "Gil" | 70% Complete

Size: About 9 meters (30 feet) long.

Availability: Delivery 6-9 months from date of acquisition.

Locality: Judith River formation of Montana.

Description: A large adult specimen, missing the rear legs, neck and skull. Bone quality is excellent. The specimen is otherwise virtually complete, and during field excavation, many areas of skin impressions were discovered, with more promising to be found during preparation. The specimen is articulated. Rib cage, hips, one arm and the tail are all complete. We recommend mounting this specimen in its death pose, as the right arm is extended forward, ribs pointing up, and tail straight out. It could be mounted as-is, or the rear legs could be composited in, as could a neck and skull provided from a cast specimen for completion.

Comments: This specimen is partially prepared. The natural articulation of this specimen is amazing and we intend to create an in situ mount to preserve it.

Daspletosaurus sp. "Sir William" | 30-40% Complete

Size: Approximately 36 feet (10.6m) long and 10 feet (3m) high at the hips.

Availability: Delivery 12 months from date of acquisition.

Locality: Judith River formation of Montana.

Description: This may be a new species of Daspletosaurus. Excavation of this very large theropod began in the fall of 2002 and continued during 2003 and 2004. We have obtained between 30-40% of the body from one end of the animal to the other, including many skull elements, scapula-coracoid, gastralia and ribs, femur, partial tibia, several vertebrae, ischium and more. The skull of this find suggests a more “Tyrannosaurus-like” animal than Daspletosaurus torosus, possibly indicating an intermediate form between D. torosus and T. rex.

Comments: Basic preparation is finished. Restoration will commence shortly.

Aquatic Fish & Reptiles

Aquatic Fish & Reptiles

Champsosaurus laramiensis

Size: 1.6m (5 feet) long.

Availability: Delivery 2-4 months from date of acquisition

Locality: Judith River formation of Montana. 78 million years old.

Description: Champsosaurus is a common find as small clusters of isolated teeth, vertebrae and scutes, but rare as relatively complete skulls or skeletons. This specimen is about 5 feet (1.6m) long, for which we have about 75% of the post-cranial and a few skull parts. Fossil is 78 million years old.

Comments: It is mostly prepared at present, and needs to be restored, reconstructed and mounted.

Basilemys variolosa “Doug”
