The fish remains as represented in the above faunal list, with one 
exception, have a wide geologic range and are valueless as horizon indicators. 
Platceodon has only been reported from the Lance formation of Wyoming, 
Likewise the batrachia, represented by the single genus Scahpherpeton, 
is of little use because of the fragmentary nature of the known materials 
and also since it occurs in the Judith River formation of Montana. 
None of the turtle specimens are sufficiently well preserved to be 
identified specifically, and with one exception all of the genera recognized 
have a wide geological range and none is distinctive of the Lance fauna. 
Thescelus if present has not been recognized below the Lance, though a 
second species occurs in the Puerco. 
The single rhynchocephalian reptile, Champsosaurus, has a wider 
geologic range than any other of the extinct reptiles listed, with the excep- 
tion of some of chelonian genera. Champsosaurus remains have been 
found in the Judith River, Belly River, Two Medicine, Edmonton, Lance, 
Puerco, and Fort Union formations. 
The Sauria (lizards) are represented by two specimens: one pertaining 
to the genus Iguanavus the genotype of which is from the Bridger, 
Eocene, but which has also been reported from the Lance of Wyoming; 
the second specimen belongs to a new genus and species (in manuscript) 
first recognized from the Lance formation of Wyoming.
