Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.
Yesterday we went on a fieldtrip organised by my geology club in the area of Marche en Famenne. In the morning the first stop was the visit of the "Grottes de Hotton" but me and my girlfiend didn't do this visit, so we got around 11am at the grottes to wait for the rest of the group. the weather was sunny and the temperatures very pleasant, this was going to be a very nice spring day. When the group was complete we hit the road to the quarry a couple of kilometers further. first we got a quick lesson about the geology of the quarry and safety mesures ( the sediments in the quarry were of mid Devonian age: Givetian). After this we where free to prospect the area. In the screes a lot of very large corals could be found, but I passed on those until I would find a more managable specimen. but a few of our friends did make the effort to drag a few of those back to the cars. After a while I found a verry good spot where a fossiliferous clay layer was washed out. this is where I found most of the good stuf. Lots and lots of Atrypas (brachiopods ) and a multitude of different corals ( sociophyllum, favosites, scoliopora,.. ) most of these were extremely wel preserved. With further prospection of the site we found a few other fossiliferous spots, one notable one where fragments of large Stringocephalus brachiopods could be found. we even found a few more or less complete specimens. At 4 pm we gathered back to the car and the finds where compared and discussed, and of course we left for a local pub to finish this perfect day for a refreshing drink. Enjoy the pictures: One of the big corals: The memmorial at the pub: the turret of an "easy 8 " sherman tank. Some time to rest after the hard work
