LOC 30-E (cont.) Found 2 more sepioids within 8 feet of the Lucina conc. layer (C). About 35' beneath it, D.miculleti in place. Also "prenebroscensis" type in float between 5'and 15' beneath the (C) layer. Peznut brittle coocs begin to turn up lower than the Lucina conc. layer. - went across road to East to investigate. LOC 30-F - Bluffs containing Elk Butte-T.C. contact just east of Rt 63. loc. 199 Here more fossils appear in the section and succession is more apparent - need a detailed section here. Ivrosite becomes common again at the D.mic. horizon, small D.mic coocs more common. Limopsis coocs come in at first red-brow weth coocs just above Dmic, and still in ivrositic zone #1. But - local rare Limopsis accumulations also in the "C" conc layer along with rare P.nebroscensis ones and
