Kudos to Jeff Martz and Bill Parker for publication of an important paper on Petrified Forest region stratigraphy published today in the online journal PloS ONE.
The Open Source Paleontologist points out some of the benefits of an online digital publication - megabytes of color photos and maps, active links to references, and active GPS coordinates among others.
