Summary:

Abandoned earlier by Thomas (1934) but was used by Pierce and Andrews (1941). Name Embar has been applied to rocks now called Phosphoria, Park City, and Dinwoody Formations in Bighorn and Wind River basins, WY. The latter three terms are used in preference to Embar, a name abandoned (p. 5-11).
