    Blades can be made from little nodules like that. But they are not recognizable as a knapped tools. Most people see blades and assume they are debitage from knapping. And they see blade cores and know they are some type of artifact but can't figure out what.

        So my little flint stones that are broken in half, is that done my human or can the ocean have done it? Thanks by the way for all that information. I am still wrapping my head around it.




  2. I was beach combing on a different part of our coast and found a bunch of this stuff.  Some of the insides look like caramels. I love the waxy shiny look. The outside of the small stones has a specific feel and look. I imagine if I broke open some of the rounded pieces there would be interesting waxy coloured stone inside?? I can't get enough of these. I googled chert and wow there are some extraordinary colours out there.

    What are they called when they are still in an oval stone form?

    This would be what out indigenous (Beothucks-now extinct) people used for tools?

    Not sure if its granite but i love the red and green ones. Nice texture and turn out smooth.

    Does it have the sparkly veins in it?


    Sonja there are no sparkly veins. I like that red too. I am sure the green is the same as whatever is in the ones with quartz. It would be interesting to know what that red is. Some of the green ones I find are very pitted.

    It is an awesome rock!

    Looks like a quartz vein in some sort of country rock. The quartz was chemically and mechanically more durable and the country rock has mostly been eroded away. 

    A rock like that tells a good story. It's not just a dumb rock that does not give you much info. It definitely represents change and movement. The passage of time.

    You can plainly see how the harder rock is persisting and the softer stone is weathering away. The quartz was once surrounded by the dark rock but now it holds it together.

    When you look at a rock like that you can actually hear the hubs of Hell spinning around and feel the eons passing.

    Thanks! You always make me smile.

    augite, color, brown green; black; green-black; brown purplish brown.

    cleavage- distinct/good on (110) degrees.

    streak- greenish gray, light to dark brown.

    hardness- 5-6.5

    What D_day said then? botryoidal hematite? I googled that and it does look like it. Like someone carved away at it to expose the inside.

    A bath in vinegar might clean your bryzoans. I know it does wonders for mine. :)

    Maybe leave them overnight or longer and monitor it to make sure things are doing what you want them to. If that does not work try some dilute Muriatic acid. 

    The fossils will be pretty much insoluble in most acids. The limestone matrix may be pretty tough but will erode back slowly. I would start slowly with mild acid and give it time and maybe even some heat to help it long rather than using stronger acids. And remember when using muratic acid it will liberate some fumes so make sure to only do it outside and downwind. One good hit of that stuff will choke the crap out of you.

    If it bubbles a little when it hits the stone your mix is strong enough. So dilute the acid as needed to give it a gentle action. Heat it a little to increase action. Keep the reaction slow until you are confident you are getting the effect you want.

    After you use acid a dental pick will probably give them some sharp relief. The acid will weaken the limestone and you may be able to abrade it with a sharp instrument around the fossils.

    When you clean it up post the results! Tell us what worked and what you tried.



    Thanks, I daresay vinegar is the way I will go. I have to drive an hour to get the muriatic acid so maybe down the road I will try it. For sure I will post pics. Thanks again. :)

    It is fossilized some darn thing or the other. I would say it is sea life but that is a wild guess. 

    There are  stratas of fossiliferous limestone just about everywhere. That is a chunk of fossiliferous limestone that was solid enough to hang together and survive the erosionary processes for a while. You can see where the limestone eroded faster than the silicified fossils. That it why the fossil texture is raised.

    They look like worm tubes or long shells. Maybe some sort of freaky bacterial or plant life. I have no idea on what they were back then. But now they are silicon dioxide replacements in a limestone matrix. 

    Thanks!! What is a good method of cleaning stone so that the bryozoans are more clear? (I googled what you said and found that word under a similar photo..  LOL.)
