Saurichthys sp., jaw bone fragment, 50/LMK

—

in Actinopterygii, Cranial, Lower Muschelkalk, Röt

A fragment of the jaw bone of a actinopterygian fish, most likely of the genus Saurichthys.
Reptilia indet., medial gastralium, 49/LMK

—

in Fossils, Lower Muschelkalk, Miscellaneous, Reptile, Röt

A partially preserved medial gastralium from an indeterminate Triassic reptile. It is a V-shaped dermal bone resembling a rib and forming part of the gastral basket—a cage or basket-like structure protecting the organs ventrally.
Acrodus cf. lateralis, tooth, 11/UMK

—

in Chondrichthyes, Teeth, Upper Muschelkalk

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

—

in Actinopterygii, Coprolites, Lower Muschelkalk, Röt, Teeth

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

—

in Lower Muschelkalk, Actinopterygii, Cranial, Röt

The specimen is a partially preserved skull roof of a Triassic bony actinopterygian fish (cf. Saurichthys).
Eosauropterygia indet., ilium, 45/LMK

—

in Sauropterygia, Limbs, Lower Muschelkalk, Röt

A specimen of a well-preserved ilium (hip bone) from a Triassic marine reptile belonging most probably to the Eosauropterygia.
Marine carnivore coprolite, 44/LMK

—

in Coprolites, Lower Muschelkalk, Röt

A well-preserved coprolite (fossilized feces) of a marine predator. Inside the coprolite, undigested fish remains (primarily ganoin scales) were preserved, strongly suggesting a piscivorous diet.
Ichthyosauria indet. (cf. Mixosauridae), anterior caudal? vertebra centrum, 43/LMK

—

in Ichthyosauria, Lower Muschelkalk, Vertebrae

Ichthyosauria indet. (cf. Mixosauridae) Middle Triassic, Lower Gogolin Beds, Upper Silesia, Poland A vertebral centrum of a small marine reptile, likely a member of the Mixosauridae—early ichthyosaurs known from the Triassic. The centrum is short, disc-shaped, subhexagonal in outline, and tapering upward. The articular surfaces of the centrum are strongly amphicoelous. Dorsally, the floor of…
Ichthyosauria indet. (cf. Mixosauridae), distal caudal vertebra centrum, 42/LMK

—

in Ichthyosauria, Lower Muschelkalk, Vertebrae

A well-preserved specimen of the distal caudal vertebra centrum of a small ichthyosaur. In Middle Triassic sediments of Upper Silesia, finds associated with ichthyosaurs are significantly rarer than those of representatives of other groups of marine reptiles.
Saurosphargis sp., dorsal vertebra, 41/LMK

—

in Saurosphargidae, Lower Muschelkalk, Vertebrae

The specimen is a large, but unfortunately incomplete, vertebra of a Middle Triassic marine reptile. The morphology of the vertebra is consistent with dorsal vertebrae of Saurosphargis sp. reported in the literature
