Description:
Belemnitida (or the belemnite) is an extinct
order of squid-like cephalopods that existed from the late Triassic to Late
Cretaceous (201-66 mya). Belemnites were marine animals with a squid-like body
of leathery skin, tentacles that pointed forwards and a siphon that ejected
water forward, which moved it backwards. However, unlike modern squid, they had
a hard internal skeleton. In the belemnite’s tail, the skeleton formed a
bullet-shaped feature sometimes known as a guard, or more correctly, a rostrum.
It is these hard parts which are normally found as fossils, since the rest of
the animal’s soft tissue naturally decayed after death.
