It’s interesting to think about how many generations this plastic replica is removed from the original claw itself. The first generation would be the original claw from the Allosaurus. Depending upon the type of fossilization, the original claw would be replaced over time by mineral deposits in the shape of the original claw left in the surrounding material. This would make the fossil itself either a second or third generation copy. 1 The fossil was then cast into a mold once it was dug up, making that the third or fourth generation copy. The mold was used to cast a replica, which would be a fourth or fifth generation copy. That replica was photographed by gavinmurphy, making the fifth or sixth generation copy. Those photos were converted into a 3D image by 123D catch, making the sixth or seventh generation copy. The DWG or OBJ file created by 123D would have to be converted to an STL for printing, making the STL the seventh or eighth generation copy. The STL was then printed as you’ve seen above, making the eighth or ninth generation copy. The photo above would then be a ninth or tenth generation copy.
Whether nine or ten generations, this awesome claw is pretty much a must-print item if you’re looking to show off what a 3D printer can do. (Oh, you want a dinosaur? How about a life-sized dinosaur claw?!) 2

- Second generation if the original claw became a fossil directly. Third generation if the fossil was created as minerals took the shape of the claw from the surrounding material. Also a third generation copy if the original claw disintegrated leaving a claw-shaped depression in the material around where it used to be. [↩]
- Do you remember that bit from Jurassic Park where the kid calls the veloceraptor a six foot turkey? I now finally have a good reason to memorize Sam Neill’s awesome response. [↩]
