The fossil record contains ecosystem changes, and can provide insights into ecological conditions over evolutionary timescales, particularly factors affecting community structure before and after disturbance. Our current understanding of these effects is based on changes in biodiversity, which cannot capture interactions between organisms. Food webs provide an alternative approach, representing interactions within a community. Food webs present unique challenges as they require assembling paleocommunity data for species across trophic levels. Numerous sources may be used to determine the species present in a paleocommunity. However, the potential effects of differences between data derived from museum collections and data compilations have not yet been tested. Here we examined differences between food web models of Late Ordovician marine communities assembled using two types of data: museum collections and field work; and the PBDB. To determine whether both data types produced consistent outcomes, paleocommunities were compared before and after the Richmondian Invasion. Relative differences in model outcomes across the invasion did not vary between data types. Differences in structure were consistent between the datatypes, with similar changes across the invasion. These findings suggest that both data types may be suitable for studies examining differences in resistance.
