Is this bone? Weird eye ball looking fossil.

One of my finds today in north LA looks like bone but the round top is suspicious. Either way it's cool looking! Anyone seen anything like this?

Brightened and cropped the photos.

Looks like a piece of a chert nodule, or slag,  to me. :unsure: 

Wait for some other opinions, though.

 Yes. Looks like it would work better than my shoulder does some times.

I've been looking for clues in my collection. The texture does seem a little coarse and shiny doesn't it.

It seems to have the same pitting as my bone finds. This isn't the only one I have found. In fact, I know of one still in the wall of the creek bed that would take an act of congress to remove due to its size. I just don't understand how it gets its shape.

This really reminds me of the rocks we had on the track at my highschool. They were either igneous or some sort of waste product from and industrial process (aka slag). The shape and bubbles that are reminiscent of bone are caused the cooling process where it went from molten to solid. I believe what you have there is geologic/human made. You could try a scratch test to see if it's basalt, but I'm leaning more towards slag.

Slag was my first thought.

The voids (bubbles) are caused by gasses trapped in the rock (slag) when it cools. 

I agree that it looks like scoria- a volcanic rock that has a lot of gas voids.

phosphatized piece of bone with an articulating surface? I don't see bubbles on fossildude 19's improved pics. Just guessing like the rest of ya'll!
