This dataset of 2617 conodont sample locations represents conodont information compiled and studied by Anita G. Harris, USGS, emeritus. The samples were collected by many different researchers over many different years. The conodonts in the samples were all reviewed by Anita Harris at some point, and logged into her database. Many of these samples, their ages and locations have been published elsewhere in various formal and informal publications, but no comprehensive digital collection of this work has been published. The locations of the samples were taken from information provided by the collector to Anita Harris, and have not all been rechecked or verified for accuracy. Some samples are likely mislocated, and are annotated as such when this is discovered. This dataset includes valuable age and CAI information from the conodonts that is useful for geologic analysis of the rock units containing the samples.
