Hi: I was hoping someone could tell me anything about these shells/fossils found at the beach recently. They were found on the Samoa Peninsila in Humboldt County, Northern California. They are all between 2-3". My wife found the whole shell(third picture) when she was walking our dog there. I'm guessing it's a fossil of a cockle shell in limestone. I am a beachcomber and fossil hunter, so I went to the same spot to check it out. The last two times I went I found these shell fragments which appear to be agatized. Could these be fragments of fossils which have been filled in with chalcedony or quartz? One of them has a bluish moonstone like hue and they all appear to have banding. Is this possible or are these just shell fragments? They seem too thick to be shells. Any help would be greatly appreciated. I'm going to keep going back to look for more; these are cool and I've never found anything like them on the beach before.

@theoriginalrods,
sounds interesting. However, yuve posted your pix on a site that denies me access. SOOO,
Get a geology map of the County through the state geologists website . Find where your fossil locality sits , geologically speaking. If they were found in the surf, thats ok because usually the nearby geological strata were the source rocks for them. Then get a good fossil hunters book like "INVERTEBRATE FOSSILS" by Moore Lallicher and Fisher. Its quite an old text (1950's or so) but its been reprinted several times and is often used as a college text for beginning paleontology courses.
Just match your fossils to the types and ages of the pictures in the book and youll have your answers. identifying fossils is very easy, (as compared to identifying minerals and rocks which show multiple patterns for even the same mineral "Species")
