Definition of belemnite in English English dictionary: An extinct group of Mesozoic marine cephalopod, very similar in many ways to the modern squid and closely related to the modern cuttlefish
In the universal decay this volatile substance had chanced to survive, perhaps through many thousands of centuries. It reminded me of a sepia painting I had once seen done from the ink of a fossil Belemnite that must have perished and become fossilized millions of years ago.; The belemnites are found in rocks of the Jurassic and Cretaceous ages; It is the internal shell of a cephalopod related to the sepia, and belonging to an extinct family; 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; a conical calcareous fossil tapering to a point at one end and with a conical cavity at the other end containing (when unbroken) a small chambered phragmocone from the shell of any of numerous extinct cephalopods of the family Belemnitidae
