Dear Mteini Nabil,
Many thanks for sending photographs of your specimen to the museum for identification.
Your specimen is a fragment of a fossil bivalve, a mollusc that has a laterally compressed calcified exoskeleton consisting of a hinged pair of valves. The vertical lines on the rock are actually the radial ribs of the bivalve, which ornament the exterior of the shell. Although the geology of Lebanon is currently poorly studied, your specimen is likely from the Bikfaya Formation, which is comprised of limestone, and is from the Late Kimmeridgian - Early Tithonian stages of the Jurassic Period. The means that your fossil is around 149 million years old!
Great find!
Best wishes,
Emily

The Museum says "The vertical lines on the rock are actually the radial ribs of the bivalve."
