Reptilia indet., ?cranium element, 22/LMK

—

in Reptile, Cranial, Lower Muschelkalk

The specimen is a bone or bone fragment from an unidentified reptile. Structure of the bone and its robustness almost certainly rule out fish and amphibians (the lack of ornamentation typical of amphibians).
Reptilia indet., lateral gastralium, 21/LMK?

—

in Reptile, Lower Muschelkalk, Miscellaneous, Röt

Reptilia indet. Dating uncertain – Upper Röt or Lower Muschelkalk (Anisian) Upper Silesia, Poland The specimen is the lateral gastralium (ventral rib) of an indeterminate reptile. Gastralia were present in almost all Triassic marine reptiles (the exception being Ichthyosauria). Their morphology is very similar, making such specimens non-diagnostic. The specimen is approximately 56 mm long and…
Pistosaurus cf. longaevus, cervical vertebra centrum, 10/UMK

—

in Pistosauroidea, Upper Muschelkalk, Vertebrae

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?

—

in Tanystropheidae, Lower Muschelkalk, Ribs, Röt, Vertebrae

Protanystropheus antiquus (“Tanystropheus antiquus”) is an extremely rare find in Lower Muschelkalk sediments, whose systematic position is still uncertain.
Placodontia indet., humerus fragment, 19/LMK

—

in Placodontia, Limbs, Lower Muschelkalk

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

—

in Nothosauria, Limbs, Lower Muschelkalk

Specimen of Nothosaurus sp., left coracoid in ventral view. Lower Muschelkalk, Gogolin Beds, Upper Silesia, Poland
Nothosaurus sp., vertebral neural arch, 17/LMK

—

in Nothosauria, Lower Muschelkalk, Vertebrae

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

—

in Pistosauroidea, Upper Muschelkalk, Vertebrae

A beautiful specimen of a nearly complete vertebra of Pistosaurus longaevus. Middle Triassic, Upper Muschelkalk (Ladinian), Upper Silesia, Poland
Ichthyosauria indet. (cf. Mixosauridae), vertebra centrum, 16/LMK

—

in Ichthyosauria, Lower Muschelkalk, Vertebrae

Ichthyosauria indet. (cf. Mixosaurus sp.) Middle Triassic, Lower Gogolin Beds, Upper Silesia, Poland Ichthyosaur remains are extremely rare in the Muschelkalk deposits of Upper Silesia. The photos show a single vertebral centrum – though slightly damaged, it clearly displays the diagnostic features that allow for its assignment to this group of extinct marine reptiles (most…
Sauropterygia cf. Nothosaurus, dorsal rib, 15/LMK

—

in Sauropterygia, Lower Muschelkalk, Ribs

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,…
