Description from the seller
Scientific name: Keichousaurus hui, Young 1958 (marine reptile Pachypleurosauridae family)
Location: Guanglin, Guizhou Province of China
Geological Formation: Falang - Huxia Formation
Age: Early Triassic (~242 million years ago)
Size: 18,8cm long the specimen - 21 x 12,5cm x 0,6cm the matrix
Ref: S333
Observations: Here we present one of our nicely preserved Keichousaurus specimens. Its preservation is particularly remarkable. It is very common to find many fake or heavily restored Keichousaurus specimens on the market. However, this specimen is pretty good. The preservation of the bones is impressive, and the level of detail is outstanding, mainly at the skull and full vertebrae from the neck, which is fully pristine perfect even preserving some of the tiny visible teeth and all the skull bones. Also the tiny hands and legs bones (the fingers with their carpals, tarsals and phalanges), as well as the pelvic and scapular girdle. The tail vertebrae are also intact. Size its also outstanding, quite an adult individual. Its fossilization position is also very aesthetically pleasing.
It is a nice collector piece, far away from the typical bullshit. The specimen has been carefully prepared professionally using micro sandblasting. The restorations carried out consist primarily of gluing and filling fractures in the matrix. Those bones that were not as well preserved have been highlighted using a painting technique, although not many of them, mainly the ribs and dorsal vertebrae. The head (skull), neck, legs, hands, and a large portion of the tail are exceptionally well preserved.
Most of the "restoration" has been performed on the matrix fractures.
Keichousaurus hui is a small marine reptile from the Triassic of southern China. A member of the Pachypleurosauridae family, with a long neck, paddle-like limbs, and a slender tail, adapted for swimming in shallow marine environments. Fossils, often found in black shale, reveal a diet of small fish and invertebrates, inferred from its needle-like teeth.
