When was the last time belemnites went extinct?
They first appeared in the Devonian period about 416 million years ago, were particularly abundant during the Mesozoic Era, especially during the Jurassic and Cretaceous periods, but went extinct during the Cretaceous-Tertiary mass extinction .

How are the belemnites related to the coleoids?
Belemnites were coleoids, a group that includes squid and octopuses, and are often grouped into the superorder Belemnoidea, though the higher classification of cephalopods is volatile and there is no clear consensus how belemnites are related to modern coleoids.
