    Hi all. I have some questions about carboniferous fossils from Galway Menlough old not working quarry.
    https://picasaweb.google.com/achwirot/Menlough?authkey=Gv1sRgCMGYqPCUsvOwwwE#
    I have some idea about id but I'm not sure if it's correct.
    pic1 -Overtonia? 0,6cm
    pic2- Loxonema? 2,7cm
    pic3 - Brachythyris? 2cm
    pic4 - ?? 6cm
    pic5 - Linoproductus? 12cm
    pic6 - Nautiloid 3,5cm
    pic7 - Gigantoproductus? 10cm
    pic8 - Leptagonia? 1,2cm
    pic9 - pic3
    pic10 - Echinoconchus Galway Bay 8cm
    pic11 - some gastropod 2,5cm diameter
    pic12 - stratopollus? diameter 4,5cm and 5,5cm
    pic13- Gigantoproductus? 11cm
    Last pic shows rock bedding in the quarry. I would like to know what kind of rocks might be there. Is everything visean and namurian?
    Thanks.

    Any ideas? Menlough quarry is nice location for searching fossils, maybe somebody was there. Do you know some profesional books with irish carboniferous fossils?

    I've a few (old) books laying around somewhere. I'll dig em out. Reckon you're on the money with Gigantoproductus for pic 7 and looks like some form of productus in number 5. I'd reckon ditto for pic 4. 10 looks about right too. Number 6 might be a weathered criniod "stem". They can look very like that. 8 defo a Leptaena of some sort. Can be very common in some locals if my memory serves. 13 looks more like some form of spirifer to me?

    Many worry about Artificial Intelligence. I worry far more about Organic Idiocy.

    Thank you for help guys. I know that is very difficult to id brachiopods from pictures. I think that pic 5 might be Linoprotonia but the more materials I read I am getting more confused.
    I have one more question. Most o this rocks is limestone but part of them is more fragile and dividing on flat layers like shale. Is all of them were formed in the same time?
