Samples that have been assigned USGS numbers ending in PC, for this report, contain brachiopods that being retained in the P&S collections for future reference. The samples submitted were broken and prepared, revealing many more specimens than showed on the surfaces. All with determinable specimens seem to be Permian in age. A rather surprising result is their resemblance to the Permian fauna described by Cooper (1957) from Oregon. The strongest clue to this was sample 23883; the collection from 23875 was reviewed in this light, confirming the impression. Cooper dated the Oregon fauna as early Word, in terms of the Texas section. Now the earliest Word has been separated as a distinct formation and asigned to the Leonard Series. I would venture the opinion that the largest brachiopod samples, occurring in dark argillaceous limestone (23875, 23880, 23883) are all of this age (latest Leonard, possibly including early Word, as explained below). The others are Permian, but can't be dated much more precisely than that. The collection from 23878 is in a lighter colored coarser limestone, but the list is typically Permian with possible links to the East Greenland fauna that is now considered Guadalupe in age, not extreme latest Permian as shown on the Permian Correlation Chart (Dunbar et al., 1960, G.S.A. Bull. 71). |

SUPPLEMENT To report to D.H. Richter dated 12/5/69. In curating the samples and separating out those to be sent for identification of the corals, Harold Saunders noted that some of those without brachiopods were not mentioned. This supplement is in the interest of accounting to Mr. Richter for all the samples submitted. Most of these have nothing identifiale, and will be returned as requested on the transmittal sheet. Harold also noted that the report compare a Neospirifer in sample 23880 with one in 23875, but that the list for 23875 omits that genus. This is an oversight; Neospirifer is present in 23875, and should be added to the list. |
