T. rex Tooth Shard ⅞ in with Serrations in Riker Box — Hell Creek Formation, North Dakota (66 MYA)

Own a real serrated T. rex tooth. This genuine Tyrannosaurus rex tooth shard with visible serrations comes from the Hell Creek Formation of North Dakota and is about 66 million years old. At ⅞ inch, this piece preserves the razor-like serrated edge that once helped T. rex tear through the flesh of its prey. It comes displayed in a labeled Riker box.

This is the exact piece you will receive. It is a one-of-a-kind specimen, not a stock photo, so what you see in the photos is what ships. Only one is available.

Even as a fragment, it captures the power and presence of Earth's most iconic carnivore. Serrations like these are a hallmark of T. rex teeth and are what make a shard like this a standout in a collection.

A great gift for fossil collectors, educators, museum-style displays and dinosaur fans who want a step up from a small shard.
