Spinosaurus UV root glow?
Just saw this post about checking teeth with UV light, and my tooth seems similar. Shown using a 365nm UV torch

I don't have much experience, do roots glow under UV? Looking at it more closely there doesn't seem to be much detail on the root, and it looks very similar to the restored enamel section. The description mentioned repair, but did claim it had an actual root
Sellers description "This is a massive tooth, 4.88 inches long The enamel part is 2.99 inches and 1.65 inches wide at the base of the root. The tooth has most of the original enamel and a long root. Apiece of the crown has been restored at the base, near the root. The tooth has been repaired."
