Taphonomy
Collection methods and comments
Collection methods: | bulk |
Reason for describing collection: | paleoecologic analysis |
Taxonomic list comments:Barrett (ref. 9602) gives a detailed faunal list for his entire dissertation, generally down to the species level. The individual samples, however, are presented in his fig. 24 in a form that coarsens the taxonomic resolution to the genus level or even higher. It seems that the brachiopods are more likely to be reported to the genus level. |
