Strange Neogene "Fossil"


Anchiornis

Recommended Posts

In the Life and Science Museum in Durham County, there is a pit of Miocene Aurora sediments not unlike the one next to the Aurora Fossil Museum (though this one is extremely overpicked). While I was there, I found this weird thing with strange circular holes in it. It's also surprisingly lightweight as well. Could someone tell me what it might be? It looks somewhat like a reptilian scute, but it may simply be a piece of phosphate.

It looks like a drum fish jaw with socket holes where the teeth used to be.

My goal is to leave no stone or fossil unturned.

I thought it was geologic too when I first found it, but what makes me suspect that it is not geologic was how amazingly lightweight it is. It is definitely much lighter than other rocks of the same size.

The top picture resembles some of the turtle material that comes out of Lee Creek and is lightweight. However the bottom photo resembles some of the phosphate nuggets found.

if I had only seen the top pic I would say turtle but the bottom pic resembles a bony fish dentition somewhat. Whatever this is it doesn't look geologic (my opinion, not stating as fact). Perhaps a close up of the broken edge would help?

Here are the images, rotated, cropped and brightened. I am sticking with geologic on this - possibly phosphate nodule.

There is no order or pattern to the deformities in this piece. They are the same indents on both sides. it appears to be a thin crust with a different material inside.

I say geologic and not fossil also.
