Found In Daytona Beach FL

[MsLilyTiamaat]

I have lived in Daytona Beach for twenty two years,  and throughout those years, I have brought more than  just a couple hundred  seashells and stones home. BUT I have NEVER seen anything the likes of this! I am shelling every chance I get and I found this beauty in a shell pit in the ocean water about a foot deep . It's black in color and a bit heavy. Could someone PLEASE help identify this fantastic piece for me!?

This looks like fossilized bone. The concave surface is indicative of it being a vertebra, I think. Likely from a marine mammal. It's not complete enough to be certain though.

I agree bone fragment. I was thinking scapula due to its relative  length and its rapid reduction below articulating surface.

Could very well be. It may explain the cupping in the center better as well. The bone in a centrum being more robust.

Sea Turtles are one fauna that has flat featureless bone terminations...  Alligators are another.. It is a feature to focus on...
