A new Late Ordovician bubble-headed trilobite species from South West Wales and its implications for biostratigraphy
A new species of bubble-headed trilobite, Staurocephalus oliveae sp. nov., is described from 250 specimens collected from a recently discovered locality in the Sholeshook Limestone Formation (upper Katian, Upper Ordovician; Ashgill, Cautleyan Zone 1 equivalent) in the village of Llanddowror, Carma...

description | A new species of bubble-headed trilobite, Staurocephalus oliveae sp. nov., is described from 250 specimens collected
from a recently discovered locality in the Sholeshook Limestone Formation (upper Katian, Upper Ordovician; Ashgill,
Cautleyan Zone 1 equivalent) in the village of Llanddowror, Carmarthenshire. Although no fully articulated specimens
were found, the material is the most abundant and well-preserved of any Ordovician Staurocephalus species known
from Britain and Ireland, and enables the complicated 3D structure of its cephalon to be reconstructed. Staurocephalus
oliveae sp. nov. is the earliest representative of the genus recorded in Avalonia, following its presumed migration into
the area from Laurentia or Baltica. Recognition of this Cautleyan species resurrects the potential usefulness of the long
established, widely distributed, Staurocephalus clavifrons as a latest Katian (= Rawtheyan) indicator. |
