Tomahawk locality, USNM 39981Sues H.-D., Olsen P. E., et al (1994)Newark - Vinita - Tomahawk Creek"Based on conchostracans, Kozur & Weems (2007) recently dated much of the succession in the Richmond Basin and correlative units in the adjacent Taylorsville basin as early Carnian (Cordevolian), but earlier Huber et al. (1993) had argued for a late Carnian age of these strata. At the present time this controversy cannot be resolved" (Sues & Hopson 2010)
"Turkey Branch Formation" was previously used for this locality; Richmond Basin, Newark Supergroup
