TABLE 1: Beetles recognized by Scudder from the
"Interglacial clays near Scarboro', Ontario".

 

"EXTANT" forms

GROUP A:
... Are species identified by Scudder which are extant. Only one of the two identifications is correct to the species level. Scudder's Acidota crenata is a correct identification, and the species has also been found and identified from the Scarborough Formation (Morgan and Morgan, 1980b). The gyrinid identification is correct to the generic level, but it is not possible to identify this fragment (an elytron) to the species level.
  • Acidota crenata
  • Gyrinis confinis

"EXTINCT" forms

GROUP B:
... Represents a normal taxonomic approach; Platynus hindei and Platynus halli are respectively named after G.J. Hinde (from whom Scudder obtained most of the materials from Scarborough) and the New York state paleontologist, James Hall.
  • Platynus hinde
  • Platynus halli
GROUP C:
... Represents species which Scudder seems to have named in recognition of their "interglacial" nature; an apparent function of his assumption that these are extinct interglacial forms.
  • Bembidium glaciatum
  • Platynus interglacialis
  • Anthonomus fossilis
