2004 Paleobiology Wilf & Johnson dataset

This is the original database file that supplemented the following primary article:Wilf, P., and K.R. Johnson, 2004, Land plant extinction at the end of the Cretaceous: a quantitative analysis of the North Dakota megafloral record. Paleobiology, v. 30, p. 347–368. doi:10.1666/0094-8373(2004)0302.0.CO;2The original annotation on p. 351-352 of the primary article read as follows:"The complete data set used in this article is available as a single electronic file for unrestricted download from the Paleobiology Database, www.paleodb.org (under ‘‘major data sets deposited’’) or by request from either author. Detailed locality data, most of which are provided by Johnson (2002), are also archived without access restriction in the Paleobiology Database (search under the locality names in the electronic file or under ‘‘Authorizer = Johnson’’)."We often receive email requests for this file, which seems no longer to be available at the Paleobiology Database (now at https://paleobiodb.org) and is thus archived here to preserve it. However, the locality data and floral lists remain available at PaleobioDb as entered.The file is a standard Excel workbook in two tabs: 1. species by locality matrix. 2. species by 1m stratigraphic-bin matrix, using minimum abundances. See the file and the primary article for all details.
