(One) Authentic 95 Million Yr Old Mosasaurus Dinosaur Tooth Fossil w/ Certificate of Authenticity Card

The tooth is exactly as described and as shown in the photo. (Note that the ruler in the product photo is in centimeters, not inches. 2.5 centimeters = 1 inch.) My only concern is that the tooth is fairly brittle. Small, sand-like grains flaked away when I handled the tooth. I'm considering putting some sort of clear sealant on the tooth to protect it, but I'm worried that might make the tooth look fake.Bottom line: Great for display. It's very cool to hold a tooth that is over 60 million years old. But the tooth probably shouldn't be handled much.

Well worth the purchase

I bought this as an early Christmas gift. It's pretty freaking cool and comes with a certificate of authenticity and a little plastic display case. My only reason for not giving 5 stars is that you can tell the tooth I received had been broken in half and glued back together. I guess for 95 million years old and such a cheap price, that's not too shabby! But it did disappoint me a bit.

Those that say they doubt they are authentic have no idea what they are talking about. I am a collector, and it is obvious this is the real deal. The fact that they sometimes come cracked or broken is a pretty good clue it's real. If it was fake it would easily break. For this price I would order 3 just to get one that wasn't broken and would feel good about it. Mine came in flawless.

For the size of a Mosasaurus. I would of thought the tooth to be bigger. But regardless my grandson loved it. But he wanted to see the tooth and hold it. The tooth was glued in a plastic case and the authenticity was wrote on the packaging. So when he ripped open the package the authenticity wasn't in very good shape. Like most kids he wanted to check out and hold the tooth. When he opened the case the tooth was glued in the case but he grabbed it and pulled. The tooth broke in half. Very upsetting. I would not recommend for any children or anyone that wants to feel if it's real. The packaging is done poorly and they don't replace or offer refunds.
