      Possibly some form of coral?

      Probably coral

      Corals. Looking at cross-sections of them showing radial symmetry.

    Or more likely to be the calyx of a crinoid? Thanks for your help!

    And does that mean the “eggs” may actually be crinoid poo? From Wikipedia: “Faecal matter is formed into large, mucous-cemented pellets which fall onto the tegmen and thence the substrate”

    Ah! Thank you! You just helped identify some other fossils I found I the area (crinoid stalks / columns, I believe). I’ll post separately

    Look like some eggs, about 1 to 1.5mm size, in a fossil full of trilobites and Rugose corals and other bits and pieces? the rock / area it came from dates about 410 million years ago #fossil

      Hey @alex-buchanan! Looks like you have an assemblage of different sections of trilobite anatomy or the external molds of crinoids.

        According to Rockd, looks like you are collecting in the Yass Formation which is from the Upper Silurian Period and between Wenlock and Ludlow Ages. Hattons Corner Group is also a possibility.

    Even if there are multiple fossils in that one rock?

      Hi, if there are multiple specimens in a rock measure and photograph each one separately if you can. You can digitally add a circle around which specimen you are referring to in the gallery to make it clear. This enables paleontologists studying the specimens to decipher which one the entry is referring to.

    There are quite a few incomplete and not completely exposed fossils. I don’t have one with face, back, and tail available to help identification. Would it help if it’s just a single rock (even if there are

    Thanks Samantha! I don’t have the exact location on a map, but I think I’ve found it on macrostat – Ludlow to Lochovian (427.4 to 410.8 Ma) fossiliferous shale, mudstone, siltstone, black shale, limestone, quartz-lithium sandstone.

    You could be onto something. I found a lot of rubies coral nearby, but preserved differently. And I didn’t know what it was until now, so you just inadvertently helped me identify something else 😀 I’ll have a closer look at this one to compare. Thanks!

    The spirals might be Archimedes? Some of the brachiopods in this pic might help: https://pin.it/150dngL the source is from here: http://geologycafe.com/class/chapter15.html

      Have you considered a rugose coral? I have found some that look similar to this.

      Hi @Alex-Buchanan! I’m looking for resources that might help us narrow down the ID. Do you know how old this is? https://www.macrostrat.org can help! Also, for the eMuseum, we can only accept individual fossils, not multiples. Can you edit the photos so they’re of only a single specimen? Thanks, Sam
