Massive Hadrosaur Femur
MASSIVE HADROSAUR FEMUR
Anatotitan copei, or Edmontasaurus annectens
Cretaceous, Maastrichtian stage
Hell Creek Formation, Wibaux Co, Montana
The Hadrosaurids were ornithician herbivores, the duck-billed dinosaurs of the Upper Cretaceous, and as this impressive leg bone demonstrates, could grow to tremendous size. Descendants of the Iguanadon, they roamed across the northern hemisphere for the five million years prior to the K/T extinction event. Some of the most impressive of their remains have been found in the Hell Creek Formation of Montana and Dakota. The present example has a lovely woody brown patina and fine texture, particularly to the honeycombed bone interior at either end. The taxonomic history of the Edmontosaurs has been complicated and remains so, but many of the largest are classified as A.copei. A spectacular display piece, it measures 50 inches long and stands 56 inches high overall on a custom metal display stand.
