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.

Fossil hunting in the shed like many of us - I thought I'd lost this nice globular rhynchonellid in a house move years ago. From the top Campanian/bottom Maastrichtian Chalk of Norfolk, UK. I think it's Cretirhynchia sp.

Brachiopods, perhaps rhynchonellids most of all, are notoriously hard to identify without their internal features exposed. However, if you know the formation and rough location and have faunal lists it can be possible. Rhynchonella ainsliei, for example, has 26-34 costae with 5-7 of these appearing on the fold. This specimen has 30 and 5 respectively and is the only species that has so many found in this formation. It also has the correct shape and size to support the match.
