Résumé

A new fossil locality from the northeastern part of the Mascarene-Nerepis Belt, previously mapped as "Ordovician or Silurian", gives a precise Liandoverian C5 age. It occurs In a sedimentary sequence that underlies, and in part is laterally equivalent to, volcanic rocks of the Long Reach Formation. It establishes an approximate upper age limit to the Queen Brook Formation and is about the same age as the oldest fossiliferous rocks (Back Bay and Quoddy Formations) in the southwestern Mascarene-Nerepis Belt. RÉSUMÉ Un nouveau site fossilifère, daté avec précision com me Liandovérien C5, a été découvert dans la partie nord-est de la zone Mascarene-Nerepis autrefois cartographiée comme "Ordovicien ou Silurien". Le site fait partie d'une séquence de roches sédimentares qui sont récouvertes par des roches volcaniques appartenant à la Formation de Long Reach, et auxquelles elles sont également en partie équivalentes. Cette découverte précise la limite supérieure de L’âge de la Formation de Queen Brook et correspond à peu près à L’âge des plus anciennes roches fossilifères (Formations de Back Bay et de Quoddy) de la partie sud-ouest de la zone Mascarene-Nerepis.
