This is a spectacular fossil freshwater crab (Potamon sp) preserved in travertine from the Denizli Basin in Southwest Turkey. The crab itself is 7 cm wide and exhibits amazingly detailed, 3d preservation. It's totally coated and preserved as a three-dimensional outer cast within a natural cavity of a white travertine matrix. It is covered by an inorganic film of calcium carbonate.

Travertine is a type of limestone that forms around mineral springs. It is often quarried for use as a building material, and that is how these crabs were discovered, during the quarrying of the stone slabs. The travertine deposits in the Denizli Basin are Pleistocene in age, having been formed within the past 400,000 years.

这是来自土耳其西南部德涅斯利盆地、被石灰华所保存的壮观淡水螃蟹化石（Potamon sp）。螃蟹本身宽约7厘米，展示出极为细致的三维保存。它完全镶覆并以白色石灰华基质中的一个自然腔体呈现为三维外铸。其表面覆盖着一层无机碳酸钙薄膜。

石灰华是一种在矿泉周围形成的石灰岩。它常被开采作为建筑材料，因此这些螃蟹也是在开采石板时被发现的。

德涅斯利盆地的石灰华沉积属于更新世，形成于约40万年前至今。
