Brachylophosaurus canadensis is a mid-sized hadrosaurid or duck-billed dinosaur found in the Upper Cretaceous sediments of North America. One of the more notable features of this animal is the bony crest for which this animal was named. It reached lengths of about 30ft (9m) when full grown. Brachylophosaurus was first discovered in Canada in 1936. The Judith River Formation in Montana has since revealed many relatively complete and intriguing specimens. The Judith River formation in Montana is 75 to 78 MYA.

LEONARDO is a paleontologist’s dream. This dinosaur time capsule, held in near perfect preservation for 77 million years, was discovered in the year 2000. Leonardo’s one-of-a-kind preservation affords science a unique opportunity to study an extinct life form with unprecedented detail and scope. This specimen of Brachylophosaurus canadensis was discovered near Malta, Montana in the Upper Cretaceous Judith River Formation by a team from the Judith River Institute and Foundation. Since that discovery, a scientific team, more than 50 strong, has been examining these important remains. The remarkable preservation of LEONARDO allows scientists to study, not only the bones, but soft tissue as well. Skin, muscle, stomach contents, and perhaps even original proteins remain in near suspended animation. LEONARDO is truly a paleontological treasure.

Because the original fossil of LEONARDO is too fragile to mold directly, our cast has been made from a 3-dimensional digital image that was reproduced in solid form and then molded using high quality silicone molding material. Even the most minute details of the original have therefore been preserved in the casts we produce of this amazing specimen.
