    Cattle ranch you say. Sure it isn't petrified cow dung?

    I'd know the difference, I'm an expert on cow manure.

    I'm not the best, but the first several could be flint mixed with quartzite. The bluer-grey one looks more like chalcedony to me.

    The second post definitely looks like petrified wood, and that seems right for your area. If no one else chimes in, I'll ask one of my girls at work who is good at this game, later in the week.

    Point of contention: It's *bull*shit... not *cow*shit.

    Cool rocks... I'm not exactly a rockhound, but still enjoy neat stuff. I'll have to take some pics of a few rocks I've found myself. ETA: That does look like petrified wood to me... or at least some sort of fossilized plant material.

    First chunks are mostly quartzite. It often produces those conchoidal fractures like seen in flint and chert. But it's basically a quartz rich sandstone. But rock in the fourth pic looks like flint. Not uncommon to find both rocks in the same area. They are both basically quartz-based sedimentary rocks.

    I think the second post is petrified wood, tough to say.

    3 types of rocks

    In primary school we were taught that there were only three types of rocks.


    Igneous, metamorphic, and sedimentary.

    I found out that that was not true at all.

    The three types are skippers, floaters and sinkers..

    Bax, would your kids like some geodes? I have some that came from our place that you could carefully crack open for them.

    We had agates and geodes everywhere.
