Software written by Adam Lugowski for Prof. James Ogg.
Databases compiled by James Ogg and numerous contributing colleagues.

This Version 3.0 of our time-scale chart maker has calibrated all ages to Geologic Time Scale 2004 (Gradstein et al, 2004, Cambridge Univ. Press).

A listing of sources and references for these compilations is provided as a separate download, and is briefly indicated when each column is highlighted in the Choose Zonations menu. We are continuously working to incorporate other stratigraphic columns, so please check back soon for enhanced Versions, which are generally posted about once per month. We would greatly appreciate your comments and suggestions on both the visualization software and on improving/enhancing the default time-scale databases. Send comments to Jim Ogg; Purdue University, USA; jogg@purdue.edu).

Legal Matters

1. How much does TS-Creator cost?
TS-Creator is freely available at no cost to educational, non-profit and profit-oriented organizations, as well as individuals, so basically to everyone.

2. Can I use figures and charts produced with TS-Creator in publications?
Yes, absolutely! Please either include a sentence of the following kind in each caption:

Figure produced with TS-Creator (http://www.stratigraphy.org)

or - even better - reference TS-Creator using (many journals allows URLs as references):

TS-Creator visualization of enhanced Geologic Time Scale 2004 database (Version 3.0; 2007)
