    Probably more of a geology question, but given it contains fossils I’ll try and get away with it. Question being, what circumstance or conditions created a relatively even slice of this piece? Pulled it as is from a dirt wall. Wish i could dampen it for a clearer pic but i refuse to risk it anymore.

    @geoff-ruonavarra  I don’t see any fossils myself.  It looks like a piece of man made terrazzo or something that was cut with a diamond saw.  A natural break would not be that smooth and parallel sided, especially since the smooth break goes through all the clasts with no unevenness.  That’s my opinion.

    Please for in the name of all that is sacred.  All im getting from this group is doubt and disbelief.  I will post the amazing within. Also,  i swear i personally pulled this piece from roughly eight feet up a dirt wall, riddled with rocks and freshly uprooted trees with stretches of it prior and further down comprised of completely saturated clay  no less than 25 feet top to bottom. Which slowly seeped down into reservoir 30 metres from the lake. My children and I made water dishes for our pets at home for the clay was so clean and of perfect moulding consistency.  Why make that up? I ask a legitimate question. I get a a unsettling vibe every post i submit it met with scepticism at the very least probably think I’m even trolling. Has anyone bothered to take a crack at some of my other forum posts?! Surely even minor knowlede of the top 10 to 15 Cambrian creatures could recognize, that the animals depicted in many if not all are undoubtedly legitimate members. Check the micropaleontology forum. But i will now post some pics of the “man made” piece, complete with its breathtaking inhabitants and that is in fact not perfectly level, just oddly close.  Only the one end I posted to be exact. Sorry for the frustration. Im not sure if my edited inages, done to conform to file size limited are devauluing the quality to a point of unregignition. I have a meeting this wednesday at the local university with a geology  professor. He seemed legitimately exited to get a good look at them, while admittedly, was unwillingly to confirm species in particular based on simple fair quality photos, he undoubtedly agreed a closer look to id the cambrian like animals within.  Apologies for the rant,  I’m just a hobbiest, nobody rock hound, and without a phd whose going to really take the time, let alone go out of their way to help me out.  This is the first attempt I’ve made in the social media disease in just shy of a decade,  nothing like a friendly reminder i was right,  back to the stress free solitary sanity lifestyle I belong.  I do believe in what this group does in principle. Which is why I gave it a go. But, not a good fit.  Good luck with the group, keep the flow if knowledge available to those in need of it, even us amateurs when there’s time to venture all the way down the pesky pedestals. 2 attached pics of the man made slice. Hurumm.. hastily snapped to finish this.  By far the bottom tier of what this piece has to offer but maliciously angling didn’t suit my raging haste. If you view my pics in various post and see nothing…plz just ban me.

    Fossils generally dont break in a clean half like that. I dont see anything invertebrate plant or vertebrate Could be natural granite or conglomerate, but even then the air bubbles look a bit iffy. Could be a piece of man-made something from the flood or maybe something biological

    When i said flood, i mean the one which caused the dirtwall and uprooted trees

    How are these mistaken for anything but?! So disappointed with the reaction I’m reviving. 😞 if anyone offering their 2 cents and doing so without basic knowledge of Cambrian animals and has the capacity to recognize  at least the common ones, then I haven’t the words …

    Im sorry to hear you feel like you are being trolled. I am not trying to be mean. I am honestly giving my best identification. I mainly specialize in trilobites, shark teeth, and cretaceous dinosaur teeth, so I am not the best in the field. However i have done a bit of research on the Burgess Shale, where mainy of the animals you are claiming are in that isolated pebble, were first found. All of them were soft-bodied and would have decayed rapily in the 3D state which are the structures in the pebble. I do see some intresting structures, but nothing looks identifiably Cambrian to me, esspecially without any geological data for the pebble. If you find something like a Baculites or Dactylioceras ammonite in an unknown rock layer, it can be used as an index fossil, but the stuff in that pebble could be anything, including likley pseudofossils. It see some possible coral, diatom, or formanifera structures Again I have some advanced, but not all knowledge of basic cambrian animals, and I am honsetly not trying to troll you. I am trying to help you with ID
