Welcome back to. my Paleontology and Evolution website. I have also acquired the Burned Over District website (nileseldredgecom.weebly.com), following the passing of my colleague Harold B. Rollins. I will be developing an online version of a book on American evolutionary paleontology that Bud and I were planning at the time of his death in early 2017. Look for opening chapters of An American Quarryman's Journal on both websites in the near future!
