大的，近垂直的，围成的洞穴与独特的贝壳充填物与双壳类Archanodon在河道和漫滩沉积的弗拉斯期Oakota和沃尔顿组，纽约州的原地模具。洞穴被解释为由于双壳类的向上逃逸，遵循的工作者，如Dallar，贝格，托马斯，哈代和布罗德赫斯特，谁描述了类似的发生在晚古生代河流和三角洲沉积。横向进入原位Archanodonmolds的痕迹表明，双壳类在槽坝表面上移动。垂直方向，largeBeaconitesburrows类似于这里描述的，并可能同样起源于双壳类逃逸。
Large, near-vertical, endichnial burrows with distinctive meniscate fillings are associated with in situ moulds of the bivalveArchanodonwithin river-channel and overbank deposits of the Frasnian Oneonta and Walton Formations, New York State. The burrows are interpreted as due to upward escape of bivalves, following workers such as Eagar, Berg, Thoms, Hardy and Broadhurst, who described similar occurrences from late Paleozoic fluvial and deltaic deposits. Trails passing laterally into the in situArchanodonmoulds indicate that the bivalves moved around on the channel bar surfaces. Vertically-oriented, largeBeaconitesburrows are similar to those described here, and may have similarly originated by bivalve escape.
