A very rare, Top Quality Edestus heinrichi shark tooth, from Herrin, Illinois. This is a Paleozoic shark that lived in swamps that our now underground coal deposits. An excellent matrix specimen that inludes the opposing tooth mold as well. Excellent preservation, serrations, and serration detail.

Research showed that they could use their opposing teeth in a scissor-like motion or a vertical whipping motion to cut prey. It is the first animal to cut vertically. A very strange looking and unique acting shark. Shark recreation image is credited to Julio Lacerdo. These rare teeth are Pennsylvanian age from Illinois. No repair or restoration. Authenticity guaranteed. Note - shipping weight is 1.9 lbs. International "free shipping" will require supplemental postage.

An Ultra Rare, Extra Large Pappocetus lugardi (Andrews, 1920) jaw section with 3 complete molars from Morocco. Pappocetus was in the Protocetidae family of ancient whales.

This material is a new find and represents one of the earliest transition forms of the whale. Pappocetus is a protocetid (see discussion below) and a large amphibious aquatic carnivore. Pappocetus is also an ancestor of the Basilosaurus.. This material is complete and without repair. Crack fill only on some pieces. This is an opportunity to own an incredibly rare specimen from an early evolutionary stage of the modern whale. A fantastic collector's specimen. Authenticity guaranteed.
