It is hard to find anybody who didn’t find dinosaurs interesting at least at some point, whether a passing fancy as a child or a lifelong career as a paleontologist, these gargantuan creatures easily capture our imaginations. Barring the bizarre insistence of a small group of lunatics that dinosaurs never actually existed, the public is fascinated any time new species are discovered or new information about them comes to light. And you can’t doubt the dedication of Dr. Scott Hocknull who was privileged enough to go on a behind the scenes tour of the Queensland Museum when he was 12 and has spent the 25 years since then volunteering and working at the museum, landing himself a job there as a paleontologist at the tender age of 22.
On the table next to him, during his talk, he has a series of 3D printed objects. The first he shows is a tooth from an ancient possum, printed at 30 times its natural size. The model shows every detail, every cusp and is something that you can not only hold in your hands, but that also is really the only way to truly see the tooth. After all, the tooth itself is too delicate to be handled and much too small to be seen from a distance behind glass. And even though possum teeth aren’t normally high on my list of things I want to see, I realized that I may have dismissed them out of ignorance and inaccessibility more than any actual lack of interest.
Upping the cool factor even further, Hocknull showed us a detailed scan of a mudflat containing more dinosaur footprints than any other place in the world. On the surface of it (yes, pun definitely intended) it is absolutely fascinating. Laced with the footprints of the Earth’s previous tenants, long extinct, it comes home that they were once living creatures in a way that doesn’t quite hit the same as seeing their bones. However, what Hocknull was really interested lay beneath that surface. Unfortunately, it remained an inaccessible mystery until the development of sufficiently detailed CT scanning could peel away the layers and find the fossilized remains of the root systems of the plants that had been growing there.
It’s too late to bring them back to life (and clearly not a good idea), but with 3D modeling and 3D printing, more of us can fall in love not only with them, but also with paleontology all over again. Discuss this story in the 3D Printed Dinosaur forum thread on 3DPB.com.
