Prehistoric Puzzles and TimeWeb integrate as a collaborative project which I codirect with Martin Siegel, Indiana University.

We would like to thank the many students and colleagues who have worked on the Prehistoric Puzzles Project since 1996.

This project has been supported by Indiana University, Wisdomtools, and grants from the National Endowment for the Humanities and the Department of Education Fund for the Improvement for Post-Secondary Education FIPSE.
