If you have some spare cash to burn, you can back a crowdfunding project for polyhedral gaming dice made out of genuine T-Rex bone fossils. They're not cheap, though!
The bone is, apparently, ethically sourced--coming from "scraps and broken fragments" not used by museums or scientists. The dice come in three different styles (and prices!); the most expensive option is a set of dice carved from solid bone, which will set you back a whopping $599. Cheaper options include "bone inclusions", which are fossil fragments suspended in the center of clear dice, at $99; or pulverized bone, which is blended with resin, for $69. Those are for full dice sets, of course--you can also grab single dice if you don't want to splash out that much cash. Delivery is in July 2026.
In addition to the dice, the Kickstarter also offers 1:12 scale dinosaur replica skulls, 1:53 scale full replica skeletons, and fancy dice cases and stands.
