Text Appearing After Image:
Fig. 4. Two anterior dorsal vertebrae, several ribs, and a chevron of a sauropod dinosaur in situ. Oshih (Ashile) formation, Oshih Basin, August, 1923; Albert F. Johnson, collector. Owing to their much weathered and disintegrated condition, the two vertebrse were not taken. Conclusion.—Awaiting the evidence afforded by more perfect material, Asiatosaurus seems to resemble Camarasaurus in the subspatu- late form of the summit of the crowns, in its large anterior teeth diminish- ing gradually to the smaller posterior teeth of similar general spatulate pattern. We await with interest comparison of these teeth with those of the analogous African genera.
