有趣的巨大、真实的、部分解体的 Keichousaurus hui — 三叠纪早期海洋爬行动物 - 骨骼化石

Scientific name: Keichousaurus hui, Young 1958（海爪龙科海龙类）

Location: Guanglin, Guizhou Province of China

Geological Formation: Falang - Huxia Formation

Age: Early Triassic (~242 million years ago)

Size: 17 cm long the specimen - 19 x 12cm x 1cm the matrix

Ref: S531

Observations: Here we present an interesting large Keichousaurus specimen. This specimen is quite interesting because its skeleton is partially disarticulated. This indicates, taphonomically, that the animal died, began to decompose and disarticulate before its burial and final fossilization.

Its preservation its nice. It is very common to find many fake or heavily restored Keichousaurus specimens on the market. However, this specimen its pretty good. The preservation of the bones is nice, and the level of detail is outstanding, mainly at the tiny hand and leg bones (the fingers with their carpals, tarsals and phalanges), vertebrae neck, skull, ribs and the full tail. However, few bones have some restorations.

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, mainly the scapular girdle. The head (skull), neck, hands/legs, and a large portion of the neck and tail vertebrae are exceptionally well preserved. Most of the "restoration" has been performed on the matrix fractures. Right hand and left leg are missing.

It is also very interesting to observe how the veins of natural calcite that run through the rock also run through the fossil, an indicator that the bones are all authentic, since the mineralization processes that the rock subsequently underwent along its natural fractures, mineralized everything, including the parts that ran through the skeleton.

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.
