Species: clark KNAUSS, JOYCE, LYSON & PEARSON, 2011
Etymology: In honor of the PTRM volunteer, Merle Clark, who excavated the
type specimen and spent numerous hours in the field and at the museum with
three of the authors, G.E.K., T.R.?L., and D.A.P. The species epithet was formed
explicitly as a noun in apposition.
