Lockwood: Late Cretaceous Molluscan Abundance Data (Sohl and Koch)

This data set contains abundance data for fossil mollusk genera from the Late Cretaceous of the U.S. Coastal Plain published by Sohl and Koch (1983, 1984, 1987). It also contains global stratigraphic ranges, global geographic ranges, and taxonomic information for genera, downloaded from the Paleobiology Database (PBDB) at http://paleodb.org in February 2008. This data set is used to examine the link between rarity and extinction across the end-Cretaceous mass extinction in Coastal Plain mollusks.

本数据集包含由Sohl与Koch于1983、1984、1987年发表的美国海岸平原晚白垩世软体动物化石属级丰度数据。此外，数据集还包含2008年2月从古生物学数据库（Paleobiology Database, PBDB，http://paleodb.org）下载的属级全球地层延限、全球地理分布范围及分类学信息。本数据集用于探究海岸平原软体动物在白垩纪末大灭绝事件中稀有性与灭绝之间的关联。
