Pant-y-Ffynnon Quarry

Pant-y-Ffynnon Quarry is a stone quarry in the Vale of Glamorgan, Wales, around 3 kilometers east of Cowbridge and is part of the Black Mountain mountain range. It contains fissure fill deposits dating to the Late Triassic (Rhaetian), hosted within karsts of Carboniferous aged limestone, primarily the Friars Point Limestone Formation. Remains of numerous small vertebrates, notably archosaurs, are known from the fissure fills in the quarry, similar to other Late Triassic-Early Jurassic fissure fill deposits known from Southwest England and southern Wales.
