Complete Faunal list:
This page leads to the 'complete' illustrated faunal list for the Builth Inlier. We are also compiling faunal lists for nearby areas from published data: follow the links for the Shelve Inlier, Llandeilo and southwest Wales . We have also just started on a few Late Silurian fossils from one site, although we haven't yet gone through the yet to see how many are nameable.
The following is a list, by fossil group, of all the species known from the Builth Inlier, including a large number not yet described. Many are figured, and almost all will be one day. The only exceptions are where two or more species are closely related, and differ only in trivial details from the illustrated species; in these cases, the additional species and differences are noted in the captions. In the list supplied, stratigraphic occurrence is given only in broad age/environmental terms, as follows:
1: Camnant Mudstone Formation
2: Builth Volcanic Formation
3: Upper Didymograptus murchisoni Shales
4: Hustedograptus teretiusculus Shales (Llanfawr Mudstone Formation)
5: Nemagraptus gracilis Shales (Llanfawr Mudstone Formation)
