These beds, as in the Lander region, have basal sandstones, reddish 
or white, with conglomerate and clay layers below them yielding 
phytosaur and labyrinthodont bones (both types were found at 
El Rito), corresponding well with like vertebrates from the Keuper 
of Europe. Below these beds there are not less than three hundred 
and fifty feet, in the Lander and Kansas regions perhaps nine hun- 
dred feet, of more uniform red sandstones and clay layers, usually 
weathering into more vertical bluffs, that are utterly barren of all 
fossils and supposed to be of Lower Triassic and Upper Permian 
age. Below these and conformable with them, in New Mexico and 
probably elsewhere, are not less than three hundred feet, probably 
more, of prevailing coarser and darker colored, often brownish sand- 
stones, and dark-colored clay beds, yielding vertebrate remains 
hitherto considered to be of Permian age, but which in all prob- 
ability are in part at least of upper Pennsylvanian age.
