Abstract

Inaccurate stratigraphic correlations in the Hell Creek area, Montana, have led to the assumption that transitional vertebrate faunas (Bug Creek Anthills) exist in the latest Cretaceous, refuting a catastrophic turnover at the Cretaceous-Tertiary boundary. Establishment of the transitional faunas in Paleocene channels that cut down through the Cretaceous-Tertiary boundary renders the terrestrial faunal record compatible with the marine record and with catastrophic extinction.

摘要

蒙大拿州地狱溪地区地层对比不准确，导致人们认为过渡性脊椎动物群（布格克里克蚁丘）存在于白垩纪晚期，从而反驳了白垩纪-第三纪边界的灾难性转变。在穿过白垩纪-第三纪边界的古新世河道中建立的过渡性动物群，使陆地动物群记录与海洋记录和灾难性灭绝相吻合。
