    From Wikipedia: "Members of the order are distinguished by possessing two dorsal fins, an anal fin, five gill slits, eyes without  nicititating membranes, and a mouth extending behind the eyes. Also, unlike other sharks, they maintain a higher body temperature than the surrounding water".

    Very nice. This fish almost has the appearance of a skate or shark. Perhaps they were related.

    You are right, this fish (Mackerel shark) belongs to the order of Lamniformes;  Carcharodon carcharias (great white shark), Isurus oxyrinchus (shortfin mako) and Charcharocles megalodon are also members of the same order.

    Clever question! Actually it's an inlay - the original slab was not very pretty and much too small.

    @oilshale I thought the order of Lamniformes sounded familiar. I hunt for all those shark teeth down at Calvert Cliffs every other Saturday. Excellent find.
