Taphonomy of Aptian-Albian Beds in the Gebel Mistan, Maghara Area, Northern Sinai, Egypt

Manal S. Mekawy*

We can discover much information and many of the secrets of life in the past through studying fossils. Taphonomy can currently be used to reveal this information, but unfortunately, this branch of paleontology has not yet been wellexploited in Egypt, with only a small number of studies having been conducted. The present study is an attempt to understand the taphonomic conditions under which several Aptian-Albian beds from the Gebel Mistan region were deposited. The order of the beds from the base to the top is as follows; 1- Nerinea bed (Upper Aptian), 2- Coral bed (Upper Aptian), 3-Acteonella bed (Middle Albian) and Nerinea bed (Middle Albian). For each bed, the lithology, thickness, faunal content, state of preservation, packing density, orientation patterns, fragmentation, bioerosion and encrustation were described. The present study led to the conclusion that the four beds (Upper Aptian- Middle Albian) were deposited in a shallow, slightly–to-very-worm-marine environment with clear to agitated water.
