We want to give our thanks to the unending work performed by the many public and private
agencies, companies, and institutions that make our work possible. The data you view
in Terraphone has been compiled from many sources, including the United States
Geological Survey, The Paleobiology Database, the United States Bureau of Mines
(1910 - 1995...may it rest in peace through terraphone),
and Nevada Mineral and Book Company.
We also want to thank all the individual contributors to the various collections who
make their work available to the public. We thank you, and we support you. Keep up
the great work!
