Collection methods and comments
Collection excludes: | some macrofossils |
Reason for describing collection: | taxonomic analysis |
Taxonomic list comments:Harrison, 1980 describes a new species Parvulivenator watteli from "Unit A" of the London Clay (probably a name for the unit to which all these collections (units 1-11) belong). The description in George and Vincent describe this bed as containing bird remains throughout. |
