 Azraq Collection

   
 

 

Landscape of Azraq region has fascinating contrasts and dramatic geological features. Below the basalt rocks of Harrat Ash-Shaam volcanoes, three formations of sedimentary rocks rich in fauna and flora going back to the Maestrichtian, middle Eocene, and Miocene Epoch (120 – 15 million years).

 

The collection shown below comes from the oldest of these sedimentary formations, from the lowest exposed layers of what is referred to as “Muwaqqar Chalk Marl” formation. This formation is exposed in a very small area (3 Km sq) about 7 Km to the southeast of thee small volcano of Tall Hassan, 3Km s.s.east of Tall Usaykhim, and 15 Km east of the town of Azraq. A thickness of 45 meter of this formation is exposed due to erosion to the east of Wadi  Usaykhim. This outcrop is rich in Fossils including large fragments of fish and other vertebrates within phosphatic lime stone bed.

 

The fragment of a sea turtle found in this area can be dated within this formation to early to mid Cretaceous (130 - 100 million years). The complete turtle would have measured a length of about 90 cm.

 
 
 
This layer is also very rich in large ammonites and baculites. The Natural Resource Authority of the Hashemite Kingdom of Jordan has also discovered a petrified wood sample, which may indicate that this layer emerged above water for some period.

The faunal content of this layer can give us some indications to the environment in which these animals were living a hundred million years ago as a tidal flat to deep marine environment.
