    Hi
    My 9 yr old found this fossil in our driveway gravel. I've Googled it and I'm still not sure what it is. Marine brachiopod perhaps? He loves nature and science and I'd be ever so grateful if you could give us an idea of what it might be please.
    Many thanks.

    My guess would be it's a part, a slice of a Carboniferous period rugose solitary coral from 300 odd million years ago. In Ireland Carboniferous limestone is the most common type of stone to contain fossils. Places like the Burren in Clare are entirely made of the stuff. It blankets the country, so where you find it, with a bit of searching you should find fossils. :)

    Going by the size of the slice I'd identify it as one of the Caninia species. Here's a pic of two more intact ones.

    And what they may have looked like in life.

    Hope that helped.

    Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things. If you’re not aware you’re stupid, you probably are.

    Could be, though I'd expect to see the inner floatation chambers preserved so maybe it's a gastropod? Looks to be a big bugger for that mind you.

    Are they possibly bits of bivalves?

    If so they may be one of many millions of species.

    Again it could be the outer skin of a coral. IIRC the Spanish point rocks are deep water Carbniferous limestones and shales, not the usual areas for corals. It's an oddball looking thing anyway. Cool find.

    looks very like a fossilised algae or sea weed Thargor but unable to give a definitive answer, sorry.
