Happy , check out this Allosaurus fossil with amethyst growing at its center! It's likely water rich with silica and a touch of iron leeched into the bone during the fossilization process, allowing the growth of crystals over time. (1/2)

The end of a gray Allosaurus limb bone sits against black fabric, its open center facing the camera. Inside the bone, light purple amethyst crystals have grown in a pattern reminiscent of bone marrow. Below the fossil, an orange sign states, "Allosaurus fragilis with Amethyst".

This fossil is housed at the Natural History Museum of Utah in Salt Lake City, Utah. I posted this fella last year, but it's such a neat fossil that it deserves a repost! (2/2)

@punkpaleo Oh how fantastic! I've never seen a fossil where amethyst or any crystals were growing! Hope my #Geology friends here will see your post!
