Found on 1450 meters above sea level in the anti mount lebanon range (mid to northern part). Those mountains are the natural separation between syria and lebanon. a local cut on a 90 meters hill to extract construction stones exposed few fossils among the debris. Just cleaned it with water. looking very close, the agatization is cristal clear.

Looks like an amalgamation of gastropods.
