terapoza Posted December 19, 2017 Share Posted December 19, 2017 (edited) Hi. Around year ago I was exploring the area around Lough Hackett 20 km north from Galway. I found few fossils on the shore with much different fauna than typical late Visean fauna in Co. Galway. The main problem here is stratigraphy. It's similar to british Avon group of Mendips. I think all of them are Tournaisian. Fig1. Large piece of iron-stained black crinoidal limestone. Edited December 19, 2017 by terapoza Link to comment Share on other sites More sharing options...

terapoza Posted December 19, 2017 Author Share Posted December 19, 2017 Fig 3. Absolutelly no idea what could it be. looks a bit like recent Lekanespharea isopod. Link to comment Share on other sites More sharing options...

TqB Posted December 19, 2017 Share Posted December 19, 2017 Hi, I don't think there's anything easily diagnostic there, I've seen very similar material from the upper Visean (Brigantian) of NE England. I suspect the third one is a productid brachiopod with a few spine bases and prominent growth lines making it look like segments, something like Antiquatonia. 2 1 Tarquin Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 19, 2017 Share Posted December 19, 2017 I agree. The British Lower Carboniferous is zoned based on either microfossils or goniatites, and corals, sometimes by brachiopod - coral assemblages. Nothing diagnostic in these pieces that i can see.

terapoza Posted December 19, 2017 Author Share Posted December 19, 2017 Well. I ve never found such a big stems in the quarry and on the seashore.those are more than 1 cm in diameter. Usually I find 0,5 cm max. If it is Visean , is it possible that they were living on the different depths of the sea? Also my pictures are very bad quality because today is very bad light. I had one Leptagonia sp. From this site but lost it somewhere. Link to comment Share on other sites More sharing options...
TqB Posted December 19, 2017 Share Posted December 19, 2017 A different environment for the crinoids is entirely possible - you can even get get lenses of species different from the indigenous ones carried by mud slides down subterranean slopes. At one Brigantian site I know, the crinoids can be 30mm diameter while in the same bed a few miles away they're not much more than 10mm, apparently the same species though it's hard to be sure. 1 Tarquin Link to comment Share on other sites More sharing options...
terapoza Posted December 19, 2017 Author Share Posted December 19, 2017 Thanks. I will leave this subject for now until I will go again to this location and find more specimens. Link to comment Share on other sites More sharing options...
Ernest H. Williams, Jr. Posted January 26, 2022 Share Posted January 26, 2022 I do not think it is an isopod. Link to comment Share on other sites More sharing options...
