Title:
Report on Devonian and questionable Mississippian fossils submitted to the Section of Paleontology and Stratigraphy December 27, 1941

Middle Devonian
Formation:
Salmontrout Limestone
Comment:
The collections number 41-AMt-138, 179, and 180 represent the Salmontrout limestone as established by faunal comparison with the collections from that formation originally identified by E.M. Kindle. The fauna of the Salmontrout limestone contains some elements suggestive of an Upper Devonian age, but the presence of "
Spirifer
" aff.
S.
venustus
(=

of Kindle) is a cogent reason for considering it Middle Devonian as Kindle did (1908, G.S.A. Bull. vol. 19, p. 328-329).
