Re: The Emperor's New Papers

Could someone send me a PDF of this, if anyone has it?

Oheim, K.B. 2007. Fossil site prediction using geographic information
systems (GIS) and suitability analysis: The Two Medicine Formation, MT, a
test case. Palaeogeography, Palaeoclimatology, Palaeoecology
251(3-4):354-365. doi: 10.1016/j.palaeo.2007.04.005.

ABSTRACT: Fossil site discovery has traditionally been the result of
educated guesswork followed by systematic searching of terrain. This study
approached the issues of fossil site identification by looking at key
variables in a GIS setting. The data were analyzed to create a predictive
model for finding fossils, thus facilitating the process of fossil discovery
and saving time and money. Geospatial variables believed to be most useful
for finding fossils were examined and ranked on a scale from 1 to 4, with 4
being the most advantageous score for finding fossils. Weighted sum addition
combined the layers to create a suitability surface. Field testing and
subsequent analysis showed the model accurately predicted areas of high,
medium, and low fossil likelihood. Field observations and additional site
data led to model refinements and increased resolution of fossil density
distribution. The final model explained a statistically significant 90% of
fossil density variation in the Two Medicine Formation.
