Otodus chubutensis is the final step before Megalodon. Its teeth are large, broad, and finely serrated like a megalodon tooth, but many still carry small side cusplets, the last trace of the ancestors that came before. That makes chubutensis the key piece for anyone completing a megatooth lineage set. Every tooth in this collection is a one-of-a-kind specimen, measured and photographed individually.
The early to middle Miocene, roughly 23 to 15 million years ago, overlapping with the first megalodons.
The direct predecessor of Megalodon. Its teeth are so similar that some researchers consider it an early stage of the same evolving species.
A broad, triangular, finely serrated crown that closely resembles a megalodon tooth, plus small side cusplets that are often reduced or worn and sometimes barely visible.
Chubutensis is named after Chubut Province in Argentina, where the species was first described.
Otodus chubutensis teeth are found in early to middle Miocene deposits around the world, including Maryland's Calvert Cliffs, the Carolinas, Florida, and Argentina. Because the cusplets are small and fragile, teeth with both cusplets intact are the most sought-after examples.
Collecting each species in order is one of the most popular ways to build a shark tooth collection, because you can literally see the teeth grow larger, gain serrations, and lose their cusplets over tens of millions of years.
Paleocene to Eocene. Smooth edges and large side cusplets.
Eocene. Serrations appear alongside the cusplets.
Oligocene to early Miocene. Fully serrated, with sharp cusplets.
Early to middle Miocene. Larger teeth with cusplets beginning to fade. You're here.
Cusplets and root edges are the most fragile parts of these teeth, and they are often repaired or restored on the market. With more than 13 years of fossil identification experience behind every listing, we state plainly whether a tooth is fully natural, repaired, or restored. Every tooth is backed by our authenticity guarantee and a 30-day return policy.
Complete the lineage. The story ends with the largest shark that ever lived. Explore our Megalodon Teeth collection to add the final chapter to your set.
