In the cores brought of from the Iraty black shale horizon, I saw 
fragynents of scales, probably reptilian, and a tooth resembling that 
of Mesosaurus brasiliensis. 
The locality of this boring is on the western side of the coal basin 
and the Rio Bonito Beds have evidently thinned away very materially 
against the island of granite which comes up along Rio Jacuhy at 
the town of S. Jeronymo a few kilometers above.
