UPPER CRETACEOUS OF TENNESSEE 393 



fossil plants from the Cooper clay pit and from some new localities, 

 namely, three miles south of Mifflin in Chester County, near 

 Beuna Vista in Carroll County, and from the Perry Place, ten miles 

 east of Paris on the Manlyville Road, in Henry County. These 

 collections have all been submitted to Professor Berry, and he is 

 now completing a monograph report on this heretofore unknown, 

 large, Ripley flora of more than one hundred and twenty species. 

 The majority and the best specimens of this plant material came 

 from the Perry Place. This locality is a small gully exposure of a 

 lens of clay several feet in thickness on a farm belonging to Dr. J. R. 

 Perry. The fossil leaves occur in a two-foot layer of dark brownish 

 clay in the very bottom of the gully. This locality is about eighteen 

 miles southeast of Puryear and about the same distance northeast 

 of the Grable clay pit. Puryear is an Eocene plant locality made 

 famous by the recent studies of Professor Berry, ^ who has col- 

 lected and described from the Wilcox clays of Puryear the largest 

 and most beautiful fossil flora known in America. The Grable 

 clay pit is a recent opening in the Wilcox clay about twenty miles 

 southwest of Puryear and contains a great wealth of fossil plants. 

 Due to the recent workings at the Grable and due to the filHng in 

 of some of' the old classic pits, there is at present no locahty in 

 west Tennessee where so many beautiful fossil plants can be 

 obtained as at the Grable pit and the neighboring Adkins pit. Of 

 the Ripley plant locahties next to the Perry Place in importance 

 is the Cooper clay pit. All the McNairy plant locahties are shown 

 on the accompanying map and diagranmiatic section. 



Stratigraphically above the McNairy sand member in south- 

 western McNairy and eastern Hardeman counties is the Owl 

 Creek horizon or member. This is a series of micaceous sands and 

 marls about fifty feet in thickness in Tennessee that contain a 

 portion of the Owl Creek marine fauna. About fifty species have 

 been collected at Trimms Mill and other locahties on Muddy 

 Creek in Hardeman County. Among these is the Owl Creek 

 form, Scaphites iris Conrad.^ This northern extension of the Owl
