Products description

    
Here is a large and massive ichnofossil plate that shows numerous trilobite tracks of the genus  Cruziana furcifera. This mass acuminations of these trace fossils is not that uncommon and widely distributed  in the Armorican Quartzite. Very similar finds are for example also known from Spain. But usually they are not well exposed. This piece is a old find that origins from a road building site. A upper Cambrian age of this Trace fossil from Protugal was discussed. How ever a lower Ordovician age is appears more plausible in younger publications.
