Belemnite Be*lem"nite, n. [Gr. ? dart, fr. ? dart, fr. ? to throw: cf. F. b['e]lemnite.] (Paleon.) A conical calcareous fossil, tapering to a point at the lower extremity, with a conical cavity at the other end, where it is ordinarily broken; but when perfect it contains a small chambered cone, called the phragmocone, prolonged, on one side, into a delicate concave blade; the thunderstone. It is the internal shell of a cephalopod related to the sepia, and belonging to an extinct family. The belemnites are found in rocks of the Jurassic and Cretaceous ages. -- {Bel*em*nit"ic}, a. [1913 Webster]
