Your choice : Complete skeleton or skull   

One of the classic icons of natural history, Triceratops had to present a formidable defense to ward off the attacks of vicious mega-predators like Nanotyrannus and Tyrannosaurus rex. The original Triceratops skeleton from which this cast was reproduced is one of the most complete on record.

Agujaceratops was a comparatively small chasmosaurine ceratopsian known from Campanian sediments in the Aguja Formation of Big Bend National Park, Texas. This tiny juvenile specimen is closely related to some of the largest ceratopsians, including Pentaceratops and Chasmosaurus. Very few specimens are known to represent this rare genus. The specimen this reconstruction is based on includes a well-preserved, disarticulated skull. . Text by Triebold

Dromaeosaurus albertensis is one of the rarest theropods from the American west. They were closely related to Velociraptor but significantly larger. Known only from a collection of partial skeletons, this specimen represents the latest interpretation of its anatomy, composited from several individuals.

Fast, agile, and vicious, Dromaeosaurus probably hunted in packs, preying on the infirm and young of larger dinosaur species. Attacking with their lethal “killing claw”, they were able to latch onto their prey with both their feet and large clawed hands to inflict mortal wounds. Dromaeosaurus makes a frighteningly impressive exhibit as a pack cooperating in a hunt.

Albertosaurus was a small tyrannosaurid and one of the top predators of the Campanian stage of the Late Cretaceous in the northern regions of North America. The sharp teeth and massive skull of Albertosaurus were all the tools it needed to subdue hadrosaurs and ceratopsians as prey. Text by Triebold

Daspletosaurus torosus

Closely related to the larger and more recent Tyrannosaurus, Daspletosaurus had dozens of large, sharp teeth and the small forelimbs typical of tyrannosaurids. Daspletosaurus was at the top of the food chain, probably preying on large dinosaurs such as ceratopsids and hadrosaurs. Text by Triebold

Anzu wyliei

Anzu wyliei was discovered by Fred Nuss of Nuss Fossils. Fred and his bride, Candace, spent their honeymoon hunting fossils when Fred discovered the site in November of 1998. This large theropod is the largest dinosaur of its type from North America. It was fast and ferocious, with legs built for speed, forelimbs more than a meter long with large, sharp claws, a sharp beak, and almost certainly a bad attitude. Becoming popularly known as the “Chicken from Hell”, Anzu wyliei will make a fabulous addition to your displays, telling a story of diversity at the end of the age of dinosaurs. Text by Triebold

Nanotyrannus lancensis

Locality : South Dakota
Formation : Hell Creek                                   TRIEBOLD MODEL

The “pygmy tyrant” has been controversial ever since first suggested by Dr. Robert Bakker and Phil Currie in 1988 but is now represented by a number of specimens supporting its validity as something other than a juvenile Tyrannosaurus. This beautiful skeleton from South Dakota’s Hell Creek Formation is a rare example of this elusive tyrannosaurid. With many more teeth than either an adult or juvenile Tyrannosaurus, this small predator would have been able to quickly take apart a large, nutritious carcass. At 15 feet (4.6 meters) long and about 6 feet (1.83 meters) tall, a pack of Nanotyrannus overwhelming an adult Edmontosaurus makes an action-packed and engaging scene. Text by Triebold

Without a doubt, the most famous dinosaur in the world, Tyrannosaurus has enamored humanity with its majesty for over a century. At nearly forty feet long and twelve feet high at the hips, the presence of this incredible predator communicates power, authority, and brute force tempered by confident finesse. The massive skull, at over five feet long, sports a mouth full of banana-sized bone-crushing teeth evolved to penetrate the most formidable defenses and bring a swift, merciful end to its prey.

Brontosaurus (Apatosaurus) excelsus

Brontosaurus, or Apatosaurus if you prefer, was one of the large sauropods that lived in North America at the end of the Jurassic. In contrast to the camarasaurs and brachiosaurs that were contemporary in their range, Brontosaurus had a long neck held low to the ground, like Diplodocus. A historically important specimen, this massive skeleton was originally collected by a Carnegie Museum expedition and eventually given to the State of Wyoming. This enormous TPI reproduction is based on more original fossil material from one individual specimen than any other Apatosaurus or Brontosaurus skeleton. Text by Triebold

Brachiosaurus altithorax

Locality : Colorado and Wyoming                  TRIEBOLD MODEL

Your choice : Complete skeleton or skull

75 feet long and standing up to 45 feet tall, Brachiosaurus had a stance that elevated its head higher than any other land animal. Living at a time when sauropods were at their greatest size, abundance, and diversity, Brachiosaurus evolved this posture and long neck as a means to access vegetation its contemporary counterparts could not. This remarkable specimen is the famous Brachiosaurus skeleton that is on display at the Field Museum in Chicago, and at O’Hare Airport. Text by Triebold

This specimen was reproduced by scanning and 3D printing the famous Kessler Stegosaurus exhibited in the Denver Museum of Nature and Science. Discovered by a school teacher and amateur fossil hunter, Frederick Carl Kessler, in 1936 near Cañon City, Colorado, the specimen was collected by high school students under the supervision of Denver Museum paleontologists. In 1982, not just this species, but this specimen in particular was proclaimed as the official Colorado state dinosaur. The manufacturer of the handheld scanner used by Triebold was so impressed with the project results, they posted a story about it in their own blog: Artec 3D. Text by Triebold

Discovered in New Mexico in 1986, Seismosaurus was a giant among giants, at over 33 meters (110 feet) long and nearly 5.5 meters (18 feet) tall at the hips. The original specimen is housed in the New Mexico Museum of Natural History and Science. Recent research strongly suggests that this animal is a large species or individual of Diplodocus.

Mosasaurus sp.

Age : Late Cretaceous

Locality : Kansas
Formation : Weskan Shale                               TRIEBOLD MODEL                                   

Skull Length : 1.2 m (4 feet)-Skeleton approximately 11-12 meters in length

Your choice : Complete skeleton (should be available in a few months) or skull

This is the only Mosasaurus known from Kansas and almost certainly represents a new species. Its sharp teeth di­erentiate it from its known contemporary, Globidens. The nearly complete and virtually undistorted skeleton is currently under preparation and is approximately 11-12 meters in length. It should be available in a few months. Inquire as to the status of the full skeleton cast. Text by Triebold
