Sauropterygia indet. cf. Pachypleurosauria, pubis, 30/LMK
A specimen of a small, isolated pubic bone (pubis), likely from a small reptile belonging to the Pachypleurosauria. Upper Röt or Lower Muschelkalk (Anisian), Upper Silesia, Poland.

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).…

Sauropterygia indet., metapodial element, 24/LMK
—
Sauropterygia indet. (cf. Nothosaurus) Middle Triassic, Lower Muschelkalk (Anisian), Gogolin Beds Upper Silesia, Poland Probably isolated metacarpal or metatarsal bone of an unidentified Sauropterygia (most likely a medium-sized Nothosaurus). Due to the visible slight asymmetry, I think it is most likely one of the outer metacarpals or metatarsals – I or V. The bone is flattened…

Pistosaurus longaevus, cervical vertebra centrum, 10/UMK
Pistosaurus longaevus Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland Isolated vertebra centrum of Pistosaurus 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 depressions on…

Placodontia indet., humerus fragment, 19/LMK
—
Placodontia indet. Middle Triassic, Lower Muschelkalk (Anisian), Gogolin Beds Upper Silesia, Poland The specimen is most likely a distal fragment of a humerus (upper arm bone). The broad, flattened head and the strongly pachyostotic bone structure indicate a placodont. A distinct groove is visible on the left side of the head, a feature noted by…

Nothosaurus sp., left coracoid, 18/LMK
—
Specimen of Nothosaurus sp., left coracoid in ventral view. Lower Muschelkalk, Gogolin Beds, Upper Silesia, Poland
-
Nothosaurus sp., vertebral neural arch, 17/LMK
Nothosaurus sp. Neural arch. Gogolin Beds. Upper Silesia. Poland – The specimen is a beautifully preserved neural arch (in dorsal view). Considering its shape and size, it can be fairly safely assigned to the genus Nothosaurus.

Pistosaurus longaevus, vertebra, 6/UMK
A beautiful specimen of a nearly complete vertebra of Pistosaurus longaevus. Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland

Sauropterygia cf. Nothosaurus, rib, 15/LMK
—
Sauropterygia cf. Nothosaurus Middle Triassic, Gogolin Beds, Upper Silesia, Poland A rare find of a complete rib of this size from Sauropterygia indet. (probably Nothosaurus). The bone structure is clearly pachystotic – the rib is massive and the tissue dense. This structure is a primitive adaptation to aquatic life – the heavy bones acted as ballast,…
