Looks like Devil's Toenails. Tommy probably has an official name or the right one! |

Good morning, unless the colors in your photo are WAY off I don't think we're talking about the same stuff. What is the hardness - ie: will it scratch with a nail and how easily? What I have is a soft petrified mud type material, always dark gray and filled with shells in various stages of decomposition. Some of the shells take a beautiful translucent shine and some don't. I've always thought that it must have to with the angle they were situated in the stone in relation to my polishing activities. I think I remember being told by Mel ( Sabre52) that my material is collected along the California coast and there is evidence to support this because every piece I've seen is in cobble form, smooth from having been tumbled in water. I posted these photos in this thread:  |

Pattern is the same. Color is true to photo. This has been slightly polished on top and sides. I can use a diamond bit to scratch the back. Softer scratching items do not do much, including nails. I have only tried scratching on the unpolished back. Was just curious on what it might be. Tommy thanks for your input. |

That's a nice piece Beth! I just happened to be sorting through some fossil slabs today, hope you don't mind me adding to your thread. Here's a beauty I picked up in a collection a while back  other side  This one is very similar to Tommy's stuff  Indian 'Script Stone' which is also coquina  Coquina from near Malibu CA  And some 'Devil's Toe Nails' from Texas I believe  Fun stuff!  |

I posted these photos in this thread: There is, indeed, a ton of this stuff up an down the CA coast. I have a few cobbles that I always assumed would not be worth working (i.e. too soft, no shine...). I may have to revisit that theory. And, I suppose, it will matter where along the coast it was collected. |
