This is the first time that these two iconic dinosaurs of the Jurassic have been found together, in remarkable condition, and are available for acquisition with a remarkable amount of data to offer. Their early age give insight into the development and evolution of Jurassic dinosaurs in North America and their association gives them historic scientific significance. Both skeletons contain a majority of original bone and are prepared professionally with minimal restoration; the mounts are also professionally made and the bones are placed in osteologically correct position. An important feature of this pair is that they were professionally collected and documented with full locality and stratigraphic data. The greatest care has been taken to preserve and present the bones with their scientific value and significance uncompromised. This is a rare opportunity to own a unique and prestigious discovery.
