The Jurassic Belemnite Suborder Belemnotheutina
The Belemnotheutina is a monophyletic group of mostly late Jurassic belemnites that possess largely plesiomorphic characters of ten subequal arms with hooks, a simple, conical, rostrum, a narrow breviconic phragmocone and a spatulate pro‐ostracum. Although some of the best‐preserved belemnites with...
