TRANSACTIONS OF SECTION C. 483 
Museum from the Upper Cretaceous opal-bearing sandstone of Lightning 
Ridge, near Walgett, New South Wales. The specimens are opalised, 
and were found associated with other bones and shells in a similar 
condition. Evidence of Dinosaurs has already been described from the 
supposed Trias of Queensland and from the Jurassic of Victoria, but the 
new fossils are the first traces of an Australian Dinosaur of Cretaceous age. 
3. On a Tooth of a Triassic Dinosaur from San Paulo, Brazil. 
By A. Smira Woopwarp, F.R.S. 
Dr. Rudolph von Ihering submitted to the author a small tooth 
which he discovered in a red rock at San José do Rio Preto, in the west 
of the State of San Paulo, 450 kilom. from the capital. The specimen 
is solid, laterally compressed, with smooth tumid faces and sharp serrated 
edges. It lacks the basal part, but as preserved it measures 1 cm. in 
maximum width by 2 cm. in height. The serrations are uniform in size, 
relatively large, and peculiar in being inclined a little upwards, not at 
right angles to the edge. The tooth thus resembles that of the 
Thecodontosaurian Dinosaurs, which are characteristic of the Trias and 
Rhoetic formations of other parts of the world.
