The skeleton, 18 feet long and 9 1/2 feet tall, was assembled in the Natural History Museum Earth Hall, and it’s a rare beast indeed.
“Stegosaurus fossil finds are rare,” said Professor Paul Barrett, the lead dinosaur researcher at the museum. “Having the world’s most complete example here for research means we can begin to uncover the secrets behind the evolution and behavior of this intriguing dinosaur species.”
And it was the rarity of ‘Sophie,’ as the Stegosaurus is known, that led the Natural History Museum to commission Propshop to laser-scan the Stegosaurus and create a 3D digital template of the find. The entire skeleton was scanned and specific pieces were 3D printed to preserve the form of the rare fossil in the event it’s ever lost or damaged.
“We were able to use our experience in digitally scanning rare, large or one-off objects to good effect,” Enright says. “The skeleton was scanned using Lidar technology, and the data gathered from the noncontact, handheld, high-res Laser scanner was then digitally manipulated to create a highly accurate computerized model.”
According to Enright, Propshop then used the data to 3D print some of the few missing parts of the skull, the radial plates, and tail bones with one of voxeljet’s larger printers. The parts were fabricated and finished using traditional modeling methods.
Propshop also created digital and real-world models which the museum plans to use to assess the strength and bone density of the skeleton. Museum staff also plan to use the models and data to fit the pieces and discover how they may have moved in the live version of a Stegosaurus.
“We’ve been using this mix of cutting edge technology and highly skilled craftsmanship for some time now, and it’s great to see it finding new applications and reaching new audiences,” Enright says. “The Natural History Museum is thrilled with the scan data, the modeling and the 3D printed touch objects. It’s incredibly forward looking, and I’m certain there will be further scope for future collaboration.”
Barrett was amazed to find such a remarkably complete dinosaur fossil, and he says the project is critical to discovering the many secrets of the Stegosaurus.
“Finding one as complete as this, where the only major parts missing are the left arm and base of the tail, is exceptional and it’s the only Stegosaurus in the world that’s anywhere near this complete,” Barrett said. “So it’s an amazing find and a really nice acquisition for the Museum.”
