Strobilepis spinigera

Polyplacophora - Multiplacophora - Strobilepidae

Taxonomy

Strobilepis spinigera was named by Clarke (1888) [Clarke in Hall & Clarke 1888]. Its type specimen is NYSM 4815 and is a 3D body fossil. Its type locality is Hall Locality 67. Hall Locality, Menteth's Point, Canadaigua Lake, which is in a Givetian carbonate limestone in the Moscow Formation of New York.

Synonyms

Platyceras anomalum was named by Rowley (1908) [Platyceras? anomalum]. Its type specimen is Univ. Illinois, RX-75 and is a 3D body fossil. Its type locality is hillside above State Hwy. 79 just south of the bridge over Buffalo Creek, which is in a Famennian marine limestone/shale in the Louisiana Limestone Formation of Missouri.

It was recombined as Gryphochiton anomalum by Williamson (1943); it was recombined as Lobarochiton anomalum by Hoare (1976); it was recombined as Pterochiton anomalum by Hoare and Sturgeon (1979); it was recombined as Lobarochiton anomalus by Smith and Hoare (1987); it was synonymized subjectively with Strobilepis spinigera by Hoare and Mapes (1995).
