1. Green Point Marker
Inscription. 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.

French:
En l’an 2000, la Commission internationale de stratigraphie a localisé ici, à Green Point, le stratotype global de la limite entre les systèmes cambrien et ordovicien. Cette limite apparaît dans un lit de shale et de calcaire (Lit 23) affleurant sur le platier et dans la falaise exposés au sud-ouest. Elle correspond à l’apparition d’un fossile, le conodonte Iapetognathus fluctivagus, à 4,8 mètres au-dessous de plus anciens graptolites pélagiques fossiles connus.
Le site fait partie du parc national du Gros-Morne. Prélèvement et études scientifiques interdits sans autorisation.
