Abstract:

Jews stone is the larger spines of regular echinoids, especially cidaroids such as Balanocidaris glandifera, called Lapis judaicus (English: Jews’ stones; Persian: Sang-e-Jahudan; Arabic: Hajarul Yahud). It is commonly ornamented by a series of longitudinal, finely tuberculated striae. It was formed in the Late Jurassic (Oxfordian to Tithonian) in Europe, North Africa and the Middle East. The spines have a short neck and a globular head ornamented with beaded ribs. The head tapers rapidly to a point distally. In terms of provenance, spines of B. glandifera are most likely to have come from the Upper Oxfordian ’Glandarienkalk’ limestones of the Mount Hennon district of what is now southern.1
