When STAN was collected in northwestern South Dakota in 1992, we knew that Stan Sacrison had made a significant discovery. Once the bones were prepared it became clear that STAN has the best skull of any Tyrannosaurus rex ever collected! Not only was STAN’s skull virtually complete, but also the 50 plus bones were preserved in pristine condition. Careful examination of the disarticulated skull shows that T. rex had a kinetic skull. There are hinge, screw, and slip joints that allowed them to open both the upper and lower jaws, greatly increasing the gape. These joints also acted as shock absorbers.
STAN’s skull preserves a number of pathologies, or healed injuries. The cheeks (jugals) and lower jaws reveal the presence of irregular openings. One probable explanation for these holes is that they were puncture wounds received in battles with other T. rex. Smoothed edges around the holes indicate that the wounds healed. At the back of the skull on the supraoccipital crest of the braincase a portion of the bone is missing where the powerful neck muscles once attached. Directly below this compelling injury we find a round hole that is a perfect match for a front lower jaw T. rex tooth. The neck contains two fused vertebra as well as extraneous bone growth, further indicating the seriousness of the injuries STAN received, endured and recovered from, to live and fight another day.
Each bone was meticulously prepared and molded, preserving fine details of the bone texture. This attention to detail, along with STAN's provocative and compelling pathologies, makes this a truly engaging display for the casual observer as well as the dinosaur enthusiast.
A rectangular steel post at the back of the neck supports this majestic display. Built in three segments (skull, neck, and lower jaws) plus base and support post, this specimen can be uncrated and assembled easily by two people in less than half an hour!
In addition, Black Hills Institute has collaborated with Black Hills Bronze Fine Art Foundry, (almost next door to our facility in Hill City, South Dakota) to produce this exquisite specimen in bronze. Please contact us for current price and delivery schedule.
