A well-preserved specimen of the anterior slender tooth of the hybodont shark Parhybodus plicatilis.

Acrodus sp, tooth, 7/UMK
A beautifully preserved tooth crown from Acrodus sp.. The root is missing, suggesting it was much less durable than the crown itself. In fact, these occasionally broken (though still recognizable) crowns are often the only identifiable elements in the “fishy mess” of vertebrate remains I encounter.

Acrodus lateralis, tooth, 4/UMK
Acrodus lateralis Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland A beautifully preserved tooth crown from the hybodont shark Acrodus lateralis. The teeth of this species are smaller than those of Acrodus gaillardoti, with more refined ornamentation. The delicate, yet distinct, branching ridges converge to a keel that runs the entire length of the tooth.…

Palaeobates angustissimus, tooth, 13/LMK
Palaeobates angustissimus Middle Triassic, Lower Gogolin Beds, Upper Silesia, Poland A tooth from another common shark from the Middle Triassic – Palaeobates angustissimus. These teeth measure usually no more than a few millimeters. This specimen is one of the largest in my collection. Palaeobates is another durophagous shark with dentition adapted for crushing hard prey.…

Parhybodus plicatilis, tooth, 3/UMK
Parhybodus plicatilis Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland A beautifully preserved specimen of a antero-lateral tooth of Parhybodus plicatilis. This shark, unlike the genus Acrodus, was an active hunter, capturing prey with its sharp teeth. Its teeth are quite abundant in the Upper Silesian sediments of the Upper Muschelkalk, though not as common…

Acrodus sp. lateral tooth, 11/LMK
Acrodus sp. Middle Triassic, Lower Gogolin Beds, Upper Silesia, Poland A beautiful specimen of a shark tooth from the genus Acrodus, with its crown and root preserved. The dentition of these durophagous sharks was heterodont—meaning the teeth varied in shape depending on their position in the jaw. This specimen is an example of a lateral…
