Belemnite
(gcide) | 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. --
