he
exotic fossil fish is Aipichthys velifer a member of the Order Beryciformes,
Family Dinopterigidae. Aipichthys is believed to have been a predator
of smaller fish. The genus died out during the Upper Cretaceous,
leaving no descendants. There is also a fossil shrimp known as Carpopenaeus
septemspinatus, a name derived from its seven rostral spines. Finally,
there are a pair of negatives of the starfish Geocoma libanotica.
Thus the plate shows a small diversity of the shallow-water Cretaceous
ecosystem of what was to become Lebanon some 95 million years later.
