What does a belemnite fossil look like?
Fossil belemnites consist of crystals of calcite radiating from the centre of the guard. If you look at a complete guard, you can see that there is a circular hole at one end. This is the entrance to a conical hole called the alveolus. There is also a narrow slit connecting the outside of the guard to the alveolus.

The Belemnite
Belemnite is the common name applied to an extinct order (Belemnoida) of mollusks belonging to the cephalopod class. Modern cephalopods include the squid, octopus, and pearly Nautilus.

How do you polish belemnite?
Take the shortest specimen and place it in a very weak solution (1 tbls acid to 1 cup H2O) of muriatic acid (weak conc. of HCl used in pools and hot tubs) and watch it closely. After 5 – 10 min (start with 5) pull it out and rinse it. It should have a pleasant “polished” appearance.
Where can I find fossils in Delaware?
Chesapeake and Delaware Canal – Cretaceous Fossils The Chesapeake and Delaware Canal is likely the best site in Delaware for fossil collecting. When the canal was built, several formations having fossils from the Cretaceous Period (144 to 65 million years ago) were exposed.
What mineral is a belemnite guard composed of?
calcite
The belemnite guard is bullet shaped and, indeed, these fossils were commonly called ‘bullet stones’ in times past. This part of the creature, located furthest from its head, was composed of calcite and tapered to a point at the extremity.
How do you clean and polish fossils?
Scrubbing the entire fossil with vinegar can help preserve it, so work the toothbrush over all sides. Pour about 2 cups of white vinegar into a bowl and place the fossil inside if you are working with a fossil that requires a lot of cleaning due to excess debris or build-up. Let the fossil soak for about two minutes.
