4 Nature of the rocks: The nature of the rocks on which the tracks were made indicates a marine origin, composed out of dolomitic-marly limestone in regular 10-15 cm. thick layers, with the seams of marl in between. The fossils in part of the layers are chiefly of marine gastropods of shallow-water character. Imprints of terrestrial plants were found in some of the layers, indicating the nearness of the shore. In certain layers, concentrations may be observed of reddish-brown earthy material, which is obviously derived from the adjacent land area (Avnimelech and Bervoets; Khalaf-von Jaffa, 2006).

Often only the digits were imprinted but sometimes even the tarsals were pressed into the rock surface. The imprints of the tarsals show that these Gazelle : The Palestinian Biological Bulletin – Number 117 – September 2014
