Reason for describing collection: | biostratigraphic 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" |
