  Sannine Formation (Lebanon) | |
The Sannine Formation, also called the Sannine Limestone, is a Cretaceous geologic formation in Lebanon. It is a Konservat-Lagerstätte that contains a high diversity of well-preserved fish, reptiles, and invertebrates from the Tethys Ocean within its three main localities: Haqel (alternatively Hakel or Haqil), Hjoula (alternatively Hadjoula, Hajoula, or Hgula), and Nammoura (alternatively Namoura).[1]
It is one of three major Cretaceous lagerstätte in Lebanon, alongside the older (Barremian-aged) Lebanese amber and the younger (Santonian-aged) Sahel Aalma site. The Sannine Formation localities, combined with Sahel Alma, are together referred to as the "Fish Beds" of Lebanon.[1]
