32 Bulletin 9 224 



Some of the fossils colledled here are : Venericardia planicosta, 

 Meretrix fiuttalliopsis , Pedunculus idoneus, Corbula aldrichi, Pli- 

 catula filamentosa , Leda parva, L. protexta, Solemya alabamieii- 

 szs, Pseudoliva vetusta, Calyptraphorus irinodiferus , Natica clark- 

 eana, Fusus subscalarinus, Solariella sylvoerupis, etc. 



At Hamilton bluff white Buhrstone is the predominant rock. 



It is much to be regretted that time and circumstances did not 

 permit visiting the Woods bluff exposures described by Langdon, 

 near Elba on Pea river. Ozark, however, is easily accessible by 

 railroad and although the fossils near by are not well preserved, 

 they do indicate very clearly the stages of the Eocene to which 

 they belong. In the deep cut on the Midland railroad as it pass^ 

 es beneath the Savannah and Western, there is a layer about four 

 feet thick, filled with fragments of shells, some being apparently 

 whole but crumbling generally when removed from the matrix. 

 The base of this stratum is from two to four feet above the rail- 

 road track, while below and above it are layers of nearly barren 

 black clay. 



It is difficult to see why this outcrop has been referred to the 

 Claiborne horizon, for it is characfterized by a very typical upper 

 Lignitic or Woods bluff horizon. Some of the fossils are Veneri- 

 cardia planicosta, V. alticostata, Leda protexta, Corbula aldrichi, 

 Leda elongaioidea, Meretrix nuttalliopsis , Astarte smithvillensis, 

 Turritella clevelandia, Fusus i^iterstriatus , and many others. 



On the Savannah and Western road about 200 yards north of 

 this cut, Buhrstone deposits occur on the east side of the track. 

 This outcrop may be 38 feet above the cut.

 been observed, commencing about five miles east of the bluff:
