The thread http://www.thefossilforum.com/index.php?/topic/84678-adams-silurian/ was getting rather enormous, so I have decided to leave that one to deal with the Llandovery and Wenlock and put my specimens from the Late / Upper Silurian here, though I don't have a great deal of material from the Ludlow and Pridoli yet. However, I do still have some jolly nice specimens to show off here. Here are my other collection threads for the Cambrian and Ordovician ; http://www.thefossilforum.com/index.php?/topic/78887-adams-cambrian/&tab=comments#comment-832018 and : http://www.thefossilforum.com/index.php?/topic/78974-adams-ordovician/&tab=comments#comment-832912 In the mid 1980's, on the way home from one of my annual visits to the Hay-on-Wye second-hand bookshops, I managed to persuade my girlfriend at the time to take a bit of a detour and stop off at a roadcuttting just outside Aymestrey,, Herefordshire in the Welsh Borderlands. The rock here is the Aymestry (sic) Limestone Formation, part of the Upper Bringewood Beds and is Gorstian, Lower Ludlow in age, so about 426 mya and a little younger than the Much Wenlock Shale Formation. Many species of coral, trilobites and brachiopods found in the formation are the same as those found at Dudley, but the bed is noted for its massive numbers of the brachiopod Kirkidium knighti (was K. knightii),a lovely, large pentamerid. In fact, during my hour or so searching, I found almost nothing but this species, the only exception being a couple of Atrypa reticularis. The problem was that this limestone is thick and seriously hard, even the broken bits are generally huge, but I managed to obtain half a dozen reasonable specimens and about the same number of fragments. Over the years I have traded, given away or sold them, so that now I only have the best one left. Here is Kirkidium knighti : It's a shame the tip of the beak is broken off : I make index cards for all my fossils, this is the one I made for the specimens at the time, back in the mid 1980's : And today's version : There was a minor extinction between the Wenlock and the Ludlow, known as the Mulde event and it is often said to have primarily effected graptolites and conodonts, but it seems to me it had a massive impact on the bryozoan faunas of the time too. Gone are the varied stony stick and mound trepostomes that made up such an integral part of many faunas from the Middle Ordovician through to the Middle Silurian and even cystoporid groups such as the Constellariidae became extinct at this time. Trepostomes and cystoporids did survive until the end of the Triassic, but were never as important again, the bryozoan faunas would start to become dominated by fenestrids in the Devonian, though they reached their peak of diversity and distribution in the Carboniferous. I will look closely at my limited number of rocks, but I don't think I have a single Late Silurian bryozoan. I know our friend @Mainefossils studies the Late Silurian Leighton Formation in microscopic detail, but I can't recall him posting any bryozoans. Are there any, Asher, old chap? Interesting.

My job has taken me to a small town in Gloucestershire, I have noticed all the old buildings in the surrounding area are made from fossil packed sandstone! Hard for me to comprehend the amount of fossils in all these building, would love to find out where the quarry is (or was).

Hello, everybody! I have been sorting through my wenlock limestone material, Middle Silurian and have a couple of personal problematica. I am wondering if any of you brilliant folks could help me out. Here is an object which seems to be an epibiont on a Favosites coral. 5 mm long and about 1.5 mm diameter at the widest. Is it a cornulitid ? Or a single corallite of Aulopora? Something else, maybe? And another one? On a solitary rugose coral. 3 mm x 1 mm. And an example of Aulopora from Wiki to compare : And a cornulitid that looks a bit similar : I would be very grateful for any help. Then there is this. Is it the worm Keilorites? Length 1.9 cm, width 2.5 mm max.

I visted Aust Cliff on the River Severn, Gloucestershire UK back in Feburary and managed to find a large block of the 'Rhaetic Bone Bed' . Lots of bone fragments, fish teeth, even a shark fin spine! But my best finds are a paddle bone and large tooth. (Still got plenty more rock pieces to break open and search for more, so a long term project...) However i would like to I.D this Ichthyosaur in particular. Does anyone know about the early ichthyosaurs from the late Triassic? Age: 208 - 201mya (Late Triassic: Rhaetian) - Aust Cliff Paddle bone - humerus? Tooth (broken off tip sadly):

Hi found these while digging foundations. Good quality solid clay base down to at least 2 meters deep. We came across a hard object within the soft clay. This is what we pulled out. My hand for scale, the big one looks like a bone to me? Though I have no idea tbh.

I would be grateful for help with identification of this ammonite. It is Sinemurian and found in Gloucestershire.

Spiny bivalve from Upper Triassic limestone at Aust Cliff, Gloucestershire, UK
Georyx posted a topic in Fossil ID
Hi everyone, First time posting here so please forgive any dodgy formatting. I found this bivalve shell in the Upper Triassic limestone beds at Aust Cliff, Gloucestershire, UK. I posted this on Reddit and only one person managed to have a guess at a Ctenostreon bivalve genus, but they are not sure. The spines on the edge of the shell seem a bit too evenly-spaced out in my opinion. (By the way, the grooves surrounding the shell are from where I've engraved the fossil a little. I don't have the equipment to fully extract it, so I have no idea what the outside of the shell looks like). Thanks all - any help would be appreciated. - Georyx -
Found in ploughed field. In sand stone. Easily smashed off. Other shells pictured in stone. Really unsure what it is as live the furthest away from sea as anywhere can in UK....

While digging around in some bone bed (Triassic, Rhaetic, Penarth Group, Westbury Formation, Rhaetic Bone Bed Aust Cliff, River Severn, South Gloucestershire, UK.) I found this tooth. I must have cracked a ton of this stuff over recent years and have never found anything like it. Fossils of the area are marine reptiles tiles and fish. Common finds are fish teeth and coprolites, plesiosaur and ichthyosaur bones, mostly, unsurprising, vertebrae. Oh and thank you Ray @aerogrower it's first outing Your wisdom and comments please! Labial surface Lingual surface Occlusal surface Root end Stupidly I forgot to photograph the proximal sides but hopefully you can get a rough idea from the other shots.

Hi I hope someone can help me with this! I found these two very small fossils when wet sieving lower lias shell bed. They are about 2mm in size and look a bit like a cross between a crinoid and a bone-like substance. They are so small they were very hard to photograph even using the super-macro function on my camera but hopefully they are good enough for somebody to perhaps recognise what these are? I'd be very grateful as I am mighty curious! Thanks in advance. Sam

The European index fossil for both the jason zone and subzone. The white is original shell substance. One can also see in the second photo how the phragmocone has been converted to calcite.

Hi folks I've been digging through a few lumps of rock I collected a couple of years ago from Aust, Gloucestershire, UK which is rich in plesiosaur stuff among other things. I found these two pieces (three now :/ ) which were touching. I'm guessing they're plesi paddle bones. Am I right? Thanks John
