This is a very rare fish fossil showing a large Prionolepis cataphractus from the Cretaceous of Lebanon containing multiple small fish within its belly that were consumed just before its death. The fossilization had to occur rapidly before the belly contents were broken down. This fossil also contains a shrimp near the head of the fish.
Prionolepis was a predatory fish with plate-armor and large jaws. They were long and slender and moved rapidly through the water. It is remarkable that such a dynamic ecological event was frozen in time for us to see here.
