    Are these the only non-triploblasts that have have tried bilateral symmetry? I heard they're diploblasts but I'm not sure if thats true...

    They're so fricking weird and i love them. i love how nobody even knows what they were supposed to be
    >They're early bilaterians
    (glide symmetry)
    >They're probably lichen or plants
    (cholesterol shows that they're animals)
    In my opinion they're probably super duper early sponges if not related to them, the ridges between isomers are covered in cilia to capture food particles and the illusion of segmentation is because their kind of growth pattern was extremely easy to evolve

    (These are just my opinions, please dont be mad at me)

      What the frick was the logic on the lichen or plant identifications? We can tell by trace fossils they move.

      Except for Auroralumina who decided that the peace shit was boring and decided to kickstart the predator life.

        This is not the first predator. We get jellyfish earlier then this, looking the exact same as modern predatory jellyfish. It's kinda a mystery what they were eating though as there are no swimming animals besides jellyfish from the ediacaran. Everything else was living on the seafloor.

          the earliest known jellyfish fossil is dated to 505 mya. there wasn't anything that looked like a modern jellyfish in the ediacaran period.

            I did not imply either of those things. I never even used the word cnidarian in my post at all. I have no clue were you got either implication from. Please take your meds before posting on Wauf.

              that's the only way your post could have been correct. the ediacaran period ended 538 mya and the earliest jellyfish fossil is dated to 505 mya.

              please learn what numbers mean

                Thats also where you're wrong. The earliest adult jellyfish is in 505 myr but we have fossils from the doushanto formation that strongly resemble modern jellyfish larva, well within the ediacaran. Maybe do more than a google search when fact checking. Also take your meds and instead of imagining words that don't exist consider the possibility that the person you're replying to knows something you don't.

                That wouldn't be my implication but the implication of the people who actually research these fossils. I'll take their word over someone who just made an idiot of themselves on a thai cuisine forum.

                https://www.nature.com/articles/nature05682 I believe it's this one but I can't read atm because it's paywalled and I'm at work. Regardless just another line of evidence indicating jellyfish (medusozoa if you're going to pedantic) already existed during the ediacaran, molecular clock estimates put the group originating 686 million years ago and all cnidarians 741 myr. https://onlinelibrary.wiley.com/doi/10.1111/pala.12116 well before the vendobiota. Since cnidocytes are ancenstral to all cnidarians then jellyfish must've had them too and jellyfish use theirs to hunt prey. I think it's safe to say both jellyfish and predators existed before the ediacaran.

                >It's kinda a mystery what they were eating though as there are no swimming animals besides jellyfish from the ediacaran.
                No adult swimming animals.
                Plenty of larvae.

                Thats another mystery, why do only larva show up in the doushanto formation? Doesn't make much since but I can't deny it exists.

                the article only establishes that medusazoa existed before the ediacaran and makes no mention of jellyfish. not all medusazoa are jellyfish, you black ape. the auroralumina that the other anon mentioned is an ediacaran medusazoa that is not a jellyfish

                your argument makes as much as arguing that 4chinz posters existed during the pleistocene because all 4chinz posters are morons and morons existed during the pleistocene

                >polypodiozoa
                I somehow doubt that a cnidarian which exclusively parasitizes the eggs of sturgeons existed during the precambrian.
                >the article only establishes that medusazoa existed before the ediacaran and makes no mention of jellyfish
                It does actually, you'll notice in the abstract it mentions that scyphozoans (true jellyfish) first split off from other medsazoans about 635 myr, around the start of the ediacaran and when embryos start showing up in doushanto, convenient! Thanks for outing yourself for not reading anything I sourced. I won't bother with that anymore if you're not gonna read them.
                >also post source that there were any organisms with cnidocytes during the ediacaran
                Must take some cutzpah to ask this after quoting in your own post a paper which shows the ancestor of cnidarians split off from all other life nearly 100 million years before the ediacaran and diversified just before the ediacaran. Do you think jellyfish and say sea anemones evolved cnidocytes independantly? what are you even arguing for anymore?

                that's not the point. the point is that the only way your assertion that hydrozoan = jellyfish would be true is if those clades do not exist, which is clearly false

                >it mentions that scyphozoans (true jellyfish) first split off from other medsazoans about 635 my
                where in the article does it say this? conulariids do not look anything like modern jellyfish
                >Do you think jellyfish and say sea anemones evolved cnidocytes independantly? what are you even arguing for anymore?
                no, the point is that there were no cnidarians recognizable as jellyfish during the ediacaran

                Conularrids are true jellyfish, accept it or not but it's not gonna change how they are classified.

                >no, the point is that there were no cnidarians recognizable as jellyfish during the ediacaran
                Then why did you ask for a source for animals with cnidocytes? What does that have to do with anything?

                >Conularrids are true jellyfish,
                picrel is what a conulariid looks like. The only reason they are classified as scyphozoans is because they have fourfold symmetry. There is no other reason.

                They have pearls and calcified shells, so the placement of conulariids in scyphozoa is debatable. Conulariids almost certainly did not have the same lifestyle as jellyfish, and no normie on the street is going to say that this is a jellyfish.

                Scientists frick up classification all the time, especially in paleontology.

                >why did you ask for a source for animals with cnidocytes
                because you mentioned them in
