Just a few of the many fascinating troves of information (some of them gruesome) in there:
+ From Stone Darts to Dismembered Bodies, New Study Reveals 5,000 Years of Violence in Central California
Earliest Evidence of Gigantism-Like Disease Found in 3,800 Year Old California Skeleton (Interestingly, the Indians of Baja California told their missionary that the rock art had been made from "giants" who came from "the north." Read a bit about that in an excerpt from my book, Miraculous Air.)
Hallucinogenic Plants May Be Key to decoding Ancient Southwestern Paintings, Expert Says
What Really Killed the Dinosaurs? (10 minute video) (A more complicated story than one might have thought... yes, includes Chikxulub... but also the prior volcanic eruptions of the Deccan Traps and massive marine regressions)
My own interest is in the Trans-Pecos region of Far West Texas (more about the book-in-progress here).
In case you missed it, my podcast interview (with transcript) with Greg Williams, Executive Director of the Rock Art Foundation, is here.
Plus here is a batch of brief videos of some of the rock art sites in the Lower Pecos and elsewhere along the US-Mexico border, as well as other sites in the Trans-Pecos.
