Table 5. Summary of the taxonomic referrals of the specimen-level OTUs included in our analysis.
Specimens are ordered alphabetically. Diplodocids are marked with bold font, diplodocines are highlighted in green, and apatosaurines in blue. Where an assignation to a higher-level taxon is ambiguous (Australodocus), only parts of the row are highlighted.
