One of my favorite geologists and teachers is George E. Davis, Collections manager NHMLA, researcher and archivist. He oversees museum scientific collections currently containing 4-5 million individual specimens, with care and complete commitment to ethics, scientific responsibilty and integrity. Pre-historical Crustacea, Eastern Pacific, representation from the Indian, Pacific, and Antarctic oceans, as well as fossil findings from what he calls, Cambrian, Ordivician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, Cenozoic periods. Go figure...... Here are some sketches and photographs I took with permission, of specimens and amber samples for Pangean / Pre-post diluvian era strata / Continental plate tectonics [Biblical / Mural studies] ABRI / MPC HR 2008
