Welsh Trilobites

I came across an old photo I took 35 years ago of the fossil Trilobite ‘Paradoxides’ in Wales, UK. As a national fossil for Wales, this might be a candidate. Some of the largest Trilobites ever found came from the dark mudstone deposits from an ancient sea in Wales, of Middle Cambrian age approx 500 Million years old.

For those interested I’ve included a couple of links in the comments. Of additional interest is how these Trilobites, marine arthropods, form another piece of the mountain of evidence for plate tectonics connecting Newfoundland to Wales in deep time.

I have been told the outcrop no longer exists as someone (?) have taken a hammer to it, which raises important issues of Geoheritage.
