FossilDiggin Posted April 22, 2017 Share Posted April 22, 2017 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? Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 22, 2017 Share Posted April 22, 2017 Brightened and cropped the photos. Looks like a piece of a chert nodule, or slag, to me. Wait for some other opinions, though.

Rockwood Posted April 22, 2017 Share Posted April 22, 2017 Yes. Looks like it would work better than my shoulder does some times. Link to comment Share on other sites More sharing options...
Rockwood Posted April 22, 2017 Share Posted April 22, 2017 I've been looking for clues in my collection. The texture does seem a little coarse and shiny doesn't it. Link to comment Share on other sites More sharing options...
FossilDiggin Posted April 22, 2017 Author Share Posted April 22, 2017 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.

Micah Posted May 8, 2017 Share Posted May 8, 2017 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. 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 8, 2017 Share Posted May 8, 2017 Slag was my first thought.

ynot Posted May 8, 2017 Share Posted May 8, 2017 5 hours ago, Micah said: bubbles that are reminiscent of bone are caused the cooling process where it went from molten to solid. 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.

Plax Posted May 8, 2017 Share Posted May 8, 2017 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! Link to comment Share on other sites More sharing options...
