50 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1963 



28 plankton samples on a track from Cape Cod to the vicinity of Puerto 

 Rico to Bermuda. 



For another scientific cruise beginning late in March, Dr. Cifelli 

 joined the R/V Chain at Recife, Brazil, as a participant in the Inter- 

 national Tropical Atlantic Ocean Expedition. Of particular interest 

 to Dr. Cifelli were the nearly 100 plankton hauls collected which he 

 will examine for Foraminifera in connection with his long-range pro- 

 gram to study the relationship between the distribution of surficial 

 plankton ic Foraminifera and oceanic circulation in the North At- 

 lantic. Also of importance for the study of Foraminifera were the 

 12 piston long-cores and numerous bottom sediment samples collected 

 from the abyssal plain, continental slope, Orinoco shelf, and the Gulf 

 of Paria. 



In June and July Dr. Erie G. Kauffman, associate curator of inver- 

 tebrate paleontology, and F. J. Collier, museum specialist, spent 6 

 weeks completing a biostratigraphic study of the lower Colorado group 

 along the Front Range of the Colorado Rockies, tracing faunal zones, 

 refining the zonation by use of ammonites and pelecypods, and tracing 

 disconf ormities and f acies change. They were able to tie in 60 detailed 

 stratigraphic sections along the Front Range and to correlate them 

 with others in northern New Mexico and southern Wyoming, as well 

 as with others in the intermontane parks of the middle Rockies. Ap- 

 proximately 4,000 specimens were collected, predominantly pelecypods 

 and ammonites. 



Wliile studying at the U.S. Geological Survey offices in Denver, 

 Colo., during October, Dr. Kauffman spent two weekends in the vicinity 

 of Colorado Si)rings collecting from previously measured Upper Cre- 

 taceous sediments. This resulted in the addition of approximately 

 300 well-preserved pelecypods and ammonites to the collections. 



A number of short excursions to the Upper Cretaceous outcrops of 

 Maryland were undertaken by Dr. Kauffman and Dr. Norman Sohl, 

 of the U.S. Geological Survey, as part of a continuing restudy of this 

 rich but incompletely known fauna. Large collections from near 

 Brightseat, Md., include many species, particularly gastropods, never 

 before reported in the Middle Atlantic Coast Cretaceous. 



Late in August Dr. Nicholas Hotton III, associate curator of ver- 

 tebrate paleontology, and James W. Kitching, research associate on 

 leave from the Bernice Price Institute in Johannesburg, South Africa, 

 journeyed to the Appalachian Mountains in search of field occurrences 

 of middle and late Paleozoic vertebrate-bearing deposits. In quarries 

 of the Greer Limestone Co., at Greer, W. Va., they collected 

 partial skeletons, including one skull, of at least two amphibians from 

 outcrops of the Greenbriar limestone (Mississippian). While in this 

 area they examined beds above and below the Greenbriar outcrop
