1. Green Point Marker
English:
In 2000, the global stratotype for the boundary between the Cambrian and Ordovician systems was designated here at Green Point by the International Commission of Stratigraphy. It is located within a bed of shale and limestone (Bed 23) exposed in the southwest facing cliff and shore platform. The level is marked by the first appearance of the conodont fossil Iapetognathus fluctivagus, 4.8 meters below the oldest known planktic graptolite fossils.
The site lies within Gros Morne National Park. No collecting or scientific study is allowed without a permit.
