Taxonomic list comments:Lostcabinian
"Most of Wortman's collection of 1897 came from here and probably from unit 13 of measured section; unit 13 has consistently produced good specimens and matches the description of the best bone-bearing layer given by Wortman to Osborn. Granger and Olsen also made good collections here." |
