We have also shown in the last year, using DNA and phylogenetic analysis, that an organic material from a hoofed mammal, probably bison, was added to the paint as a binder or vehicle of pictographs from southwest Texas. The area near the confluences of the Devils, Pecos and Rio Grande Rivers, has some of the world's most impressive rock paintings. Our research emphasizes that region because of our proximity to it. The attached picture shows several of Pecos River style pictographs painted in black, red, orange and yellow. Our second main area of interest, cosmochemistry, utilizes noble gas mass spectrometry.
Meteorites offer the oldest known material in our solar system.
The age and transport characteristics of petroleum reservoirs are also being investigated with noble gas mass spectrometry. M. Hyman and M. W. Rowe. Effect of Water on Lower Pecos River Rock Paintings in Texas. E. J. Mawk and M. W. Rowe. Rock Art Res.
