Macrofossils of the inferred protist‐grade organism Palaeopascichnus linearis occur stratigraphically beneath glacial diamictites of the ~580 Ma, Gaskiers‐equivalent, Trinity ‘facies’ of the Rocky Harbour Formation on the Bonavista Peninsula of Newfoundland, Canada. These fossils significantly pre‐date previously reported macrofossils from Avalonia and extend the taphonomic window for moldic preservation of macroscopic organisms beyond the Gaskiers glacial event into the middle Ediacaran Period. This finding confirms the long stratigraphical range of palaeopascichnid fossils worldwide and informs discussions surrounding both the age of poorly time‐constrained stratigraphical units in Norway and Australia, and formal sub‐division of the Ediacaran System.

加拿大纽芬兰〜580 Ma Gaskiers冰川消融之前的Ediacaran大型化石

推断的原生质有机体线状古生物化石在加拿大纽芬兰的Bonavista半岛约580 Ma，Gaskiers等效的Trinity'相'的冰川铁矾下出现在地层上。这些化石显着早于先前报道的来自阿瓦隆的大型化石，并扩展了从宏观形态上对加斯基尔冰河事件至中生的埃迪卡拉安时期进行霉菌保存的辩证窗口。这一发现证实了全球范围内古太平洋古化石的地层范围很广，并为围绕挪威和澳大利亚时间紧缺的地层单位年龄以及埃迪卡拉安系统的正式细分的讨论提供了参考。
