   • 1895, H. G. Wells, chapter VIII, in The Time Machine:

     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.

   • 2017, Danna Staaf, Squid Empire, ForeEdge, →ISBN, page 101:

     The guts of fossilized marine reptiles are packed with belemnites, and it's been theorized that some prehistoric sharks even died from the overconsumption of heavy belemnite shell guards.
