Partial banner stone?

[revasius]

Good morning. I'm seeking assistance in identifying an item I found several years ago in the Calvert formation, MD. The team on the Fossil Forum are divided on an ID. Some believe it is a partial, very surf worn banner stone while others say it's a concretion. Due to the uniform hole drilled through the piece I'm leaning towards artifact. Any assistance will be appreciated.
Regards,
Rich

Looks like a concretion, I see no signs of drilling.

Don't think it's for an Atlatl, but possibly the end for an ancient "Sling" for throwing stones. Appears to have had rope tied through it. Would have been at the end of the sling.

Or possibly this....

"Whistling" bulletsEdit
Some bullets have been found with holes drilled in them. It was thought the holes were to contain poison..... the holes would cause the bullets to "whistle" in flight and the sound would intimidate opponents. The holed bullets were generally small and thus not particularly dangerous. Several could fit into a pouch and a single slinger could produce a terrorizing barrage. Experiments with modern replicas demonstrate they produce a whooshing sound in flight. [21]
