Help identifying fossil/bone vs phosphate


Kbsib

Recommended Posts

I am learning the differences between rocks, phosphate and fossils. All are abundant on the beach here. This piece has thrown me. There are areas that look bone like. Other areas not so much. The two holes and sheen on parts of the item made me not automatically dismiss it. However it is very worn. Any special ways you use to distinguish between rocks and fossils in a situation like this. I’m learning and both success and mistakes teach me something. Thanks!

All of your specimens are phosphatized bone. Each exhibits the porous texture of bone (think "marrow")

I’ve never heard the term phosphatized bone but will be researching that now. Thanks for the ID. It explains some of my confusion. I could see the porous texture but there was very little smooth surface. I’m guessing the bone is just very worn.
