Occurrence, morphology, and taxonomy of the late Cambrian Laurentian dikelocephalid trilobite Osceolia Walcott, 1914

This dataset provides details of the occurrence of Osceolia Walcott, 1914 as discussed in the accompanying paper. This data includes the field notes of previous collections made and a list of specimen information associated with the repositories they are stored in. The table included here provides the detailed notes made by authors during the study of varied specimen and respository collections. We include bivariate plots of the variance explained by each relative warp for the sclerites analyzed and morphometric measurement error analysis. The raw data files used for running the geometric morphometrics analyses are also included in the supplementary material. , , # Data from: Occurrence, morphology, and taxonomy of the late Cambrian Laurentian dikelocephalid trilobite Osceolia Walcott, 1914

## Description of the data and file structure

This dataset corresponds to a related article about a late Cambrian trilobite, *Osceolia* from the St. Lawrence Formation and the overlying Jordan Formation in the Upper Mississippi Valley. The material provides further support for the analytical results and discussions presented in the main study including specimen repository information, further information on the analysis of morphological variation in the specimen dataset, *Osceolia* locality information deemed not essential to include in the main text, field-notes of the earlier workers that collected data relevant to *Osceolia* occurrences and information about the geographic and stratigraphic occurrence of the nomen nudum \"*Osceolina diabolo\"*. The sclerites of *Osceolia* analyzed here were ...,
