Abadia Formation, between Raquejada and Polentinos members.
150m SE from Polentinos, Near Cervera del Pisuerga, Palencia Province, Cantabria, Northern Spain.
Early Devonian (Emsian stage)
This is a true Xiphogonium trilobite. The locale is now in Montaña Palentina National Nature Reserve, so collecting fossils
has been banned there since 2000.
I have a larger trilobite from Jorf, Morocco that is probably also in the genus Xiphogonium, but it is undescribed.
