We intend to make available the major contributions of the early researchers (Edward Hitchcock, Richard Swann Lull, C. H. Hitchcock, and James Deane). These works are out of print, no longer under copyright, and difficult to find in libraries! We hope you will find them useful.
The articles are in pdf format, and are essentially facsimiles of the originals, for the most part with very little reformatting. Oversize figures have been reduced to fit on a single page for ease of printing, with the scaling noted on the page. The full-size versions are also included. The figures have speckling and are not pristine - the originals from which they were scanned are in varying states of decay and disintegration! I have no plans to update the files with "clean" copies.

The names of the various stratigraphic units in the Newark Supergroup have changed several times since Edward Hitchcock and Richard Swann Lull wrote their works. These lexicons are provided so that you can determine the current stratigraphic terminology for Hitchcock and Lull's footprint and bone horizons.
