Rio Bonito Beds 
The top of the Rio Bonito beds was apparently struck in No. 
11, at a depth of 278 meters, but the drill probably had not fully 
penetrated them when the boring was abandoned. No coal was reported 
from the well, but much bituminous slate was found in the interval 
from No. 11 down to the bottom. 
Near the top of No. 2 a specimen of silicified wood was found 
on the surface which David White identifies as Lycopodiopsis Derbyi, 
Renault. 
At Iraty in the state of Parana, the following succession occurs, 
heginning about 20-25 meter below the horizon of the Iraty black shale
