A recently discovered single limb bone and a possible ilium of a tetrapod
from the Clare Shale Formation of County Clare (Pennsylvanian, Bashkirian;
Chokerian-Kinderscoutian) is the oldest stratigraphically well-constrained
tetrapod skeletal fossil material described from Ireland. The limb bone is
considered to be part of the zeugopod as it lacks features characteristic
of humeri, femora or autopod elements. The ilium has a unipartite dorsal
process characteristic of colosteids, nectrideans, temnospondyls and the
stem-tetrapod Aytonerpeton. The specimens extend the known geographical
range of lower Pennsylvanian tetrapods. Although of limited taxonomic
value, the bones form an important part in our understanding of tetrapod
diversity and evolution during the transition from the Mississippian to the
Pennsylvanian. The specimens are not typical representatives of the
associated marine fauna and are considered to have been transported
offshore from a terrestrial source.
