12.4" Fossil Pachycephalosaurus Femur - Montana

 
 
 
 
 
 
This is a 12.4" long femur of the dinosaur Pachycephalosaurus ("thick headed lizard"). It was collected from the Hell Creek Formation in Glendive, Montana. This femur comes with a metal display stand. When displayed on the stand, the entire specimen is 13.2" tall.

There are several repaired cracks throughout this bone, however the restoration is minimal with some gap fill scattered throughout some of the cracks.

  • Pachycephalosaurus was a bipedal dinosaur that lived during the Late Cretaceous period and probably was about 15 feet in length.

  • Pachycephalosaurus had a distinctive, large, bony, dome on top of it's skull up to 10 inches thick to cushion it's brain from impacts.

  • Some paleontologists believe this thick skull may have been used for head-butting, much like rams while others contend it may have been a sexual display.

  • It was one of the last non-avian dinosaurs before the K-T extinction event, 65 million years ago.

  • There is only one known species of Pachycephalosaurus, Pachycephalosaurus wyomingensis. It's remains have been found in Montana, South Dakota and Wyoming.

  • It was either a herbivore or an omnivore with small leaf shaped teeth which would have been very effective at shredding plants.
