Bathytormus alaeformis

Bivalvia - Carditida - Crassatellidae

Taxonomy
Crassatella alaeformis was named by Conrad (1830) [DISTRIBUTION: Paleocene-Eocene; Gulf Coastal Plain.]. Its type specimen is ANSP 30498, a shell, and it is not a trace fossil.

It was recombined as Crassatellites alaeformis by Clark and Martin (1901); it was recombined as Crassatella (Bathytormus) alaeformis by Glibert and van de Poel (1970); it was recombined as Bathytormus alaeformis by Wingard (1993).

Synonyms
  • Crassatella declivis was named by Heilprin (1880) [DISTRIBUTION: Paleocene-Eocene; Gulf Coastal Plain.]. Its type specimen is USNM 2490, a shell, and it is not a trace fossil.

    It was synonymized subjectively with Crassatella alaeformis by Clark (1895); it was synonymized subjectively with Bathytormus alaeformis by Wingard (1993).
  • Crassatella capricranium was named by Rogers and Rogers (1839) [DISTRIBUTION: Paleocene-Eocene; Gulf Coastal Plain.]. It is not a trace fossil.

    It was synonymized subjectively with Crassatella alaeformis by Clark (1895); it was recombined as Crassatellites capricranium by Ward (1985); it was synonymized subjectively with Bathytormus alaeformis by Wingard (1993).
