Saurichthys sp., jaw bone fragment, 50/LMK
—
A fragment of the jaw bone of a actinopterygian fish, most likely of the genus Saurichthys.
-
Acrodus cf. lateralis, tooth, 11/UMK
—
A specimen of a shark tooth from the genus Acrodus (Acrodus cf. lateralis). From the Upper Muschelkalk (Middle Triassic, Ladinian) deposits of Upper Silesia. Relatively unusually, the tooth has a preserved root.
-
Bobasatrania scutata, upper dental plate fragment assoc. coprolite, 47/LMK 48/LMK
—
A limestone slab containing two fossils: a fragment of a crushing dental plate from a Triassic fish, probably Bobasatrania scutata, and a small coprolite of a marine predator containing undigested fish fragments.
-
Actinopterygii indet. (cf. Saurichthys), partial cranium, 46/LMK
—
The specimen is a partially preserved skull roof of a Triassic bony actinopterygian fish (cf. Saurichthys).
-
Palaeobates angustissimus, teeth, LMK/28 LMK/29
—
Two specimens of lateral nad ?anterolateral teeth from the Triassic hybodont shark Palaeobates angustissimus. They were found in a single piece of limestone matrix, so I decided to describe them together.
-
Polyacrodus sp., tooth, 9/UMK
—
Polyacrodus sp. Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland A beautifully preserved specimen of a shark tooth crown, Polyacrodus sp., belonging to the order Hybodontiformes. My observations indicate that the teeth of these sharks are significantly less numerous in the Ladinian sediments of Upper Silesia than those of other hybodonts. This is the only…
-
Parhybodus plicatilis, anterior tooth, 8/UMK
—
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.…
