Quote from GSI
"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."
