Two more interesting specimens that I have never figured out the proper name for. Presumably these both belong to the subgenus Erronea (Adusta). However, three different species of this subgenus have been described from the Chipola Formation, so I am not sure exactly which species these specimens are.
The specimen in the first photo was collected from a grassy sandy facies, whereas the specimen in the second photo is from the basal beds of the formation.
