I agree.

This looks like a broken but well worn piece of mammalian shoulder girdle/scapula.

Seal or dolphin?

I agree with a mammal bone part.

If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Looking at the photos the edge exposing the inner of the bone looks to flat to be a natural break.

I suspect this is a saw cut edge  so the animal would most likely be a domestic type animal and not that old.

So will not be fossilised and the colouration would be due to tanins and the like in the water.

I disagree, I think this definitely could be a fossil with the edge tumbled down, if you look closely you can see that the edge is not perfect and probably did belong to an ancient marine mammal.

Looks like a fossil to me.

Tap it with a spoon. If it rings like fine china it is. If it's a lower pitch it's most likely is modern.

The shape of this bone would have a snowshoe effect meaning slightly less pressure/area would compress the sediment beneath it until relatively late in diagenesis. Perhaps it could create the force to snap it this way ?

Thanks to all for your feedback. Did the burn test and no smell , sorta sounds like china. As a novice I’m still unsure however I’m very curious and appreciate all your help!

I am skeptical that this is not a saw mark, but we don't have an edge-on view. Looks like a land mammal to me.
