October 18-1919 Saturday Norman. Left in the 8 A.M. train for Midmore to see Dr. Hanman, the state Geologist and the collections of fossils. Sat 7. on Dr Hanman at 9.30 Fossils from the Jackfruit formation collected by C. Dr. Storeren in 1919. Grey sandstone (number 941) with a small bifoliate Lepido- ceras of the Brisonian series, deadum. I think White could identify it. It suggests an old form. Grey calcareous or weathering chert, st. brown (943) has small round corinoid stems and tiny fragments of byssora. All are works. This piece should be completely broken up to preserve the fossils. Same as before (944) same rounded and petaloid corinoid columns and some fragments of byssora. 943-4 are of some value. No 925 only sandstone shows core-in-core. Suggests casts of Articoridea but are core-in-core. No 942 grey sandstone with leaf and wood casts suggesting Conducts. Fragments broken from 943 and 944 with the same fossils as above. The byssora casts suggest bifoliate forms like Cyatrodichya or Stictopora. Stips from under about 3/16 inch across. All casts. There are a few other fragments of organisms but I cannot make the out. There is also a blade dentohypera-like form. No 976 yellow rhyne cementation broken piece, about 2 inches also a Michelini'a in diameter. Suggests Columbaria or Calaprocia. Coralite plain like open cone and ridged lines of spirals. Tabulas ascending and. Works like Tabulata and yet I can't say what it is.
