Abstract

This is the first report of organic-walled tentaculid remains from Givetian through Frasnian age deposits of the Michigan and Appalachian Basins in western Laurussia. This adds to the geographic scope of similar finds that have been described from the Frasnian through the Famennian in eastern Laurussia. However, those previous specimens were retrieved through palynological preparations and more closely resemble sheath structures rather than the full forms found herein, which were retrieved through complete maceration with ammonium surfactants.

Laurussia (NY, MI, OH)阿巴拉契亚和密歇根盆地晚泥盆世(frasian)沉积物的有机壁触手

这是第一份关于洛俄罗斯西部密歇根盆地和阿巴拉契亚盆地从吉维期到Frasnian时代沉积物的有机壁帐篷遗迹的报告。这增加了类似发现的地理范围，这些发现已被描述为从劳俄罗斯东部的Franian到Famennian。然而，这些先前的标本是通过孢粉学制备获得的，更接近于鞘结构，而不是本文中发现的完整形式，后者是通过用铵表面活性剂完全浸渍获得的。
