Collection methods and comments
| Collection excludes: | all microfossils,some macrofossils,difficult macrofossils |
| Collection methods: | surface (in situ),field collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: bivalves only | |
| Taxonomic list comments:bivalves only**abundances are given as counts ONLY for those species with fewer than 100 specimens - for 100 or more, he just gives "A" for "abundant". In the case where a collection includes an "A", we enter abundance classes for species instead of counts as follows: Fewer than 10 specimens = R (rare)10 to 99 specimens = C (common)Greater than 99 specimens(Dockery's "A") = A (abundant)In this reference, "specimens" equals "valves"
Since the very abundant taxa were not counted past 99 specimens, they were listed with a category of A otherwise, categories are listed in the comments field, absolute abundances are given in the abundance field. | |
