Hi all, I collected this piece of rock from Saundersfoot beach last week. Because it was loose on the beach, I don't have much indication of formation or age, but I'm aware that the majority of rocks in that area are Carboniferous, and I'm also aware that Carboniferous chert does exist in the Pembrokeshire region. I'm not sure where it could have came from otherwise. The fossil in question is a scoop-shaped, hemispherical mold in chert which features two discontinuous troughs running down its centre. Upon closer inspection, the surface of the mold furthest from the camera is lined with dimples (seen on the second and third image) The near side of the mold is also textured with dimples which are somewhat larger and double-ringed, however they do not show up well in images. I've made a cast of them using blu tack, which better shows their texture. To me, the dimples are reminiscent of either a trilobite cephalon or an echinoid test, though the shape of the overall fossil doesn't seem to match. Any ID or suggestions would be much appreciated!

Hi everyone! I found this yesterday on a pebbley/rocky shore near Solva in Pembrokeshire, West Wales, UK. Does anyone have any ideas what it could be? The stone is roughly 15cm x 15cm and was found on the mid shore. Thanks in advance! Hannah

Hiya, had this fossil for a few months now and i've been wondering what it is. My geology teacher seems to think it is an annelid worm but i'd like to know a little bit more. Thanks. Date: 27th November 2012 Location: Whitesands Beach, Pembrokeshire. Rock Type: Limestone Rock Age: Cambrian (I think) Dimensions: 4.8cm x 0.5cm #1 #2 #3
