LOCALITY 80 Prob 2 diffe laminar The bentonite + cone-in-cone of section 73 (unit ) is conspicuous here and has jauosite associated with it in prominent bouts for about 4 to 5 feet beneath the cone-in-cone layer. Large sphenociscids locally present loose in silty shale above the bentonite (15'+). Bru, weath, purplish cones with yellow calcite are slumped along foot slope locally and yielded to ammonites (Sample 1) These cones could be coming in above big bentonite or out from below it - can't tell here. Upper bentonite in here too but most the fossiliferous cones seem to be coming in above it. At least 25' of beds with cone zones above it here 31
