630 J. C. Branner — Estancia Beds of Bahia, 



•were overlapped by fossiliferous Cretaceous beds on the south- 

 west, while to the west they rest upon an older series of sedi- 

 ments, sandstones, and shales probably Carboniferous and 

 Devonian, that form the crest and southern flank of the Serra de 

 Itabaiana. At the time limestones were found near the Estan- 

 cia red beds east of the Serra de Itabaiana and above the, red 

 beds at Itaporanga, but it was not then clear that the limestones 

 were part of the Estancia series. No fossils have yet been found 

 either in the sandstones or the limestones of the Estancia series 

 in Sergipe.

Northeast of Estancia the red sandstones were found at and 

 about Itaporanga, and at Sao Christovao. East of the latter 

 place they have not been found in the state of Sergipe. 



In 1907 I sent an assistant, Roderic Crandall, into the 

 region north of Timbo and he reported that the Estancia red 

 beds appear on the Rio Real some fifty to sixty kilometers 

 north of Timbo and that they extend up-stream some fifteen 

 kilometers above the village of Campos and eastward to Rio 

 Piauhy, crossing that stream at Lagoa Vermelha. From this 

 point they form a narrow belt that extends northward to 

 Lagarto and thence follow clown Rio Yasa Barris. He found 

 the western margin of this .area in the state of Bahia about 

 thirty-five kilometers southeast of Bom Conselho. The struc-
