454 E. T. DUMBLE PKOBLEM OF TEXAS TERTIARY SANDS 



The clays overlying these Corrigan sands he called the Fleming beds. 



Til his work in Grimes and Brazos counties, Kennedy-^ found two series 

 of sands, the lower of whic-li he called the AVollborn sands and correlated 

 with the Fayette sands. He made the other the basal member of his 

 Navasota beds. Fossils were found at Williams quarry, in the Stephen- 

 son league, east of Wellborn, near the base of the Wellborn sands. They 

 were as follows :-^ 



Yoldia claihornensis Corbula alahamiensis 



Venericardia planicosta Turritella sp. 



Cytherea 'bastropcnsis Cancellaria penrosei 



Siliqua simondsi Plcuroionia qiiassalis 



Mactra sp. a Cylichna kcllogii 



No fossils were found in the ISTavasota sands. 



In the section along the International & Great Northern Eailway the 

 sands between Riverside and Huntsville were supposed, on account of 

 lithologic resemblance and the number of palmetto leaves they carried, 

 to represent the Oakville sands, and the overlying clays between Hunts- 

 ville and Willis were, on stratigraphic and lithologic ground, correlated 

 with the Lagarto. The clays underlying the Oakville at Eiverside were 

 thought to be Frio.-- 



In 1895 Kennedy, in an article on "The Eocene Tertiary of Texas east 

 of the Brazos River,'' -^ correlates his Fleming beds south of Corrigan and 

 around Woodville, Tvler Countv. witli tlic Frio clavs of west Texas and 

 the underlying "Corrigan" sands, including tliose at Stryker, Corrigan, 

 Lovelady, and Wellborn, with tlie Fayette. Speaking of the plant re- 

 mains of these sands, he says :^* 



"Palm wood is plentiful, while the stems and leaves of the palmetto, rushes, 

 and marsh-grass may be found in some localities in abundance, showing that 

 when these beds were being deposited the marshy tracts of the Yegua clays 

 to the northward were .still the home of such growths. None of these are 

 Indigenous to the Fayette sands and exist there only in the form of drift 

 material cast up by the sea. Near the top of the Fayette (Corrigan) sands 

 we find trunks and limbs of trees of large size, many of them even now show- 

 ing diametric measurements of over 3 feet; and although some show a length 

 of 25 or .30 feet, the greater portion of the logs do not exceed 10 or 12 feet in 

 length. Occasionally a stump with the larger roots attached may be found, 

 but this is exceedingly rare- A peculiarity regarding these trees is that they
