If this determination be correct, the rocks in which the bones were found may 
be regarded as of Triassic age. Scaphonyx ig also to be considered as the first 
fossil land-reptile discovered in South America which clearly belongs to the fauna 
of «Gondwana Land ».

These conclusions of Dr. Woodward agree with the general 
geologic succession from a stratigraphic and lithologic standpoint, 
and they also appear to agree with the conclusions of Dr. Orville 
A. Derby who has had such a long and intimate acquaintance with 
Brazilian geology. 
The fossil woods were submitted to Dr. David White of the 
National Museum, Washington, D. C., but Dr. White has not yet 
been able to report upon them. At Santa Maria they are quite abundant 
in the cuts of the railway, 2 kilometers east from the station, and 
30 to 40 meters above the level of the reptiliferous beds. 
The water draining from these and underlying rocks is sometimes 
brackish showing the presence of salt, as near Bofete in Sdéo Paulo 
according to Mr. Camargo, who has tested the water. 
It is one of the basal sandstones of these beds at Bofete on 
the fazenda of Mr. Camargo which is saturated with asphaltic 
material, specimens of which submitted to Professor Hite for analysis 
yielded the fallowing results:
