Heavy Rock with coral, shells etc - Top View HD quality 3000*1999

More detailed view of the top view of a rock found on a beach Co Waterford Ireland. Has been soaked in vinegar and slowly showing up more details. Area is know for mid-Ordovician fossils dating from around 470 million years ago. The rock is13*10*6 cm. Very heavy and seems to be more like a fine compacted ash than limestone. There is a shell in it that can be seen on the left, corals and outlines can also be made out.

Quote from GSI for area

"The mix of useful animal groups makes this an important site for biostratigraphical correlation

within the Ordovician Period, both in Ireland and internationally. It is even more important

because the animal species present at Tramore were biogeographically differentiated into

different faunal provinces in older rocks, and the site will be very important in understanding

the breakdown of the faunal provinciality within the Iapetus Ocean that once separated

northwest Ireland from southeast Ireland. Tramore appears to have been a key site for the

early migration of North American species into the Anglo-Welsh (and Irish) area."
