Ichthyosauria indet. (cf. Mixosauridae), anterior caudal? vertebra centrum, 43/LMK
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
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.

Eosauropterygia indet. cf. Nothosaurus, dorsal neural arch, 38/LMK
A well-preserved neural arch of an indeterminate member of Eosauropterygia from the Lower Muschelkalk (Middle Triassic–Anisian). Despite a damaged/missing neural spine, it clearly displays characteristic features of the dorsal vertebrae. The specimen also presents an interesting taphonomic puzzle.

Eosauropterygia indet. cf. Nothosaurus, cervical vertebra centrum, 37/LMK
The specimen is a very well-preserved cervical vertebral centrum of an unidentified Middle Triassic aquatic reptile belonging to the clade Eosauropterygia.

Eosauropterygia indet. cf. Nothosaurus, neural arch, LMK/32
Eosauropterygia indet. cf. Nothosaurus Middle Triassic, Lower Muschelkalk (Anisian), Gogolin Beds The specimen represents an isolated neural arch referable to an indeterminate eosauropterygian. The specimen is visible from the dorsal side while the ventral side is still embedded in the matrix. The measured length is approximately 23 mm and the width is approximately 27 mm. The…

Eosauropterygia indet. cf. Nothosaurus, cervical vertebra, LMK/31
Eosauropterygia indet. cf Nothosaurus Middle Triassic, Lower Muschelkalk (Anisian), Gogolin Beds A nearly complete cervical vertebra (centrum and neural arch preserved) of an indeterminate Sauropterygia from the Lower Muschelkalk (Middle Triassic, Anisian) of Upper Silesia. The specimen consists of a complete, well-preserved centrum and a neural arch partially damaged by erosion. The centrum is approximately 13…

Placodontia indet., vertebra centrum, 26/LMK
Vertebral centrum of an indeterminate placodont from the Lower Muschelkalk (Middle Triassic) of Upper Silesia, Poland. Despite abrasion, the specimen preserves features typical of placodont vertebrae, including clearly amphicoelous articular surfaces.

Sauropterygia indet., ?dorsal vertebra, 25/LMK?
Sauropterygia indet. Dating uncertain – Upper Röt or Lower Muschelkalk (Anisian) Upper Silesia, Poland This is a beautiful vertebral specimen, interesting for at least several reasons. Despite erosion, this nearly complete vertebra provides an excellent illustration of vertebral morphology. The preserved features and processes appear consistent with the general anatomy of Sauropterygia (Nothosaurus sp. for example).…

Pistosaurus cf. longaevus, cervical vertebra centrum, 10/UMK
Pistosaurus cf. longaevus Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland Isolated vertebra centrum of Pistosaurus cf. longaevus. Despite abrasion and incompleteness (the neural arch is missing), the specimen’s features allow for a number of conclusions. The centrum is flattened. In dorsal view, the articulation surfaces (pedicular facets) of the missing arch are visible as…

“Protanystropheus antiquus” cervical vertebra assoc. Reptilia indet. cervical rib, 20/LMK?
—
Protanystropheus antiquus (“Tanystropheus antiquus”) is an extremely rare find in Lower Muschelkalk sediments, whose systematic position is still uncertain.
