What is the dominant fossil found in Belemnite chalk?

Explanation:
Belemnite Chalk is named for its abundance of belemnites, ancient cephalopods that look like dart-like relatives of the modern squid. The protective, bullet-shaped remains of these creatures, called rostra, accumulate in huge numbers when belemnites die, so they become the most common fossils you find in this rock. The environment of the Late Jurassic to Early Cretaceous seas favored belemnites, and while other fossils like oysters or ammonites can occur, they don’t appear in the overwhelming quantities that belemnites do in Belemnite Chalk. So the hallmark fossils of this chalk are the belemnites, the ancient cephalopods related to modern squids.
