摘要从新西兰第三纪层序中描述了两个新的遗迹化石产状。它们包括墨尔奇森附近渐新世的一大批动植物，以及怀拉拉帕古新世下中段的一大批和一小批球粒陨石。此外，在威拉拉帕的上古新世-下始新世，岩藻斑纹被识别为横跨Zoophycos Septa的剖面。Zoophycos结构被解释为沉积物中蠕虫状动物系统性采矿活动的产物。类似的球粒陨石组合也出现在奥地利的复理石沉积物中。
Abstract Two new trace-fossil occurrences are described from the New Zealand Tertiary succession. They consist of a large variety of Zoophycos from the Oligocene near Murchison, and the association of a large and small variety of Chondrites from the Lower - Middle Paleocene of the Wairarapa. Also, fucoidal markings in the Upper Paleocene - Lower Eocene of the Wairarapa are identified as sections across the Zoophycos septa. The Zoophycos structures are interpreted as the product of systematic mining activity by a worm-like animal in the sediment. Similar Chondrites associations occur in flysch sediments of Austria.
