This assemblage of fossil plants proves the Tubardo series to be 
closely related to the Lower Karroo or Ecca series of South Africa, as 
well as to the Karharbari Group of the Condwana system of India. 
Above the Joaquim Brance fossil plant horizon at Minas, Santa 
Catharina, there comes a succession of sandy shales and massive 
sandstones, some of which are conglomeratic, but no other fossilife- 
rous beds or coal seams have been found up to about 65 meters higher, 
at the horizon of the. 
Bonito Coal Bed 
This coal seam has been designated from the river of the same 
name along whose waters it has been explored in the vicinity of 
Minas, Santa Catharina. The bed in question appears to be confined 
to the Minas region since no coal of merchantable thickness has ever 
been found elsewhere at this horizon in South Brazil. 
Throughout the Minas field the bed appears to be entirely per- 
sistent, since it is present whenever its horizon is exposed. Several 
openings on this coal have been made in the past, and they are desi- 
gnated on the accompanying map as Bonito I, II, Ill, etc. 
The structureof this coal is well exhibited at Bonito opening n. J, 
near the road leading from Minasto Treviso, and one kilometer and 
a half from the railway station, where the following section is 
exposed :
