  • Cerutti Mastodon Site Abstract 02-06-18
    The Cerutti Mastodon site: evidence for hominins in southern California 130,000 years ago. Thomas A Deméré San Diego Natural History Museum Steven R. Holen Center for American Paleolithic Research Abstract The Cerutti Mastodon (CM) site was discovered and excavated along State Route 54 in San Diego over a 5-month period during the winter of 1992-93 and yielded the partial remains of a single American mastodon (Mammut americanum) in association with evidence indicating that hominins used hammers and anvils to break the limb bones and molars. The bone assemblage and associated cobbles are contained within a fine-grain silt/sand in a low-energy overbank depositional setting. The taphonomic evidence for human agency is diverse and includes bone impact features (e.g., cone flakes, bulbs of percussion, and a large arcuate impact notch with associated negative flake scars); stone impact and usewear features (e.g., negative flake scars, Hertzian initiations, deep cracks and angular fractures); bone, tusk, and stone distribution patterns (e.g., femoral diaphysis fragments clustered around a single large cobble, detached femoral heads positioned side-by-side, and vertically oriented tusk); differential bone breakage (e.g., intact fragile ribs vs. sharply broken heavy limb bones); and bone, molar, and stone refits (e.g., 80-cm displacement of 5 pieces of a partial femoral diaphysis, 3-meter displacement of 3 pieces of single molar, 3-meter displacement of 7 pieces of a single large cobble). Significantly, most CM bones and stones were enclosed within crusts of pedogenic carbonate that establish a “chain of evidence” showing that breakage and positioning of objects at the site occurred many thousands of years ago, and, as we contend, before burial of the site.

Thus in order that they may not remain as eternal demons with a selfish nature, God send them out clothed in skin and to live of their own using their brains and learning to live. Since outside of Eden, the law of entropy was the default law, they are no susceptible to death. God had his plan of redemption without violating the freedom of any of his children. Until all creation is redeemed, since creation is always part of God himself with whole universe within God as the only reality is God, God himself will be in torment and pain. Yet that is what having children mean - even on earth. Adam carried the selfish ego DNA as a Son of God went out into the world outside of Eden, with the only profession he knew as an Agriculturalist.

  • Caught in the Act! a Bearded Capuchin Monkey Smashes a Quartz Cobble on an Anvilstone in the Serra Da Capivara National Park in Brazil
    Volume 33, Number 3 ■ July, 2018 Center for the Study of the First Americans Department of Anthropology Texas A&M University 4352 TAMU College Station, TX 77843-4352 www.centerfirstamericans.com Caught in the act! A bearded capuchin monkey smashes a quartz cobble on an anvilstone in the Serra da Capivara National Park in Brazil. Witnessed and filmed by archaeologist Tiago Falótico of University of São Paulo, the monkey shattered the cobble, then threw it aside and licked up the dust, apparently to ingest the mineral and vegal content. Of interest to archaeologists is a sharp-edged fragment created by the monkey as a by-product, which exactly mimics a conchoidal fragment made by a human flintknapper. Lithics analysts consequently caution of the need to refine the “criteria commonly used to distinguish intentional hominin lithic assemblages.” This instance of monkey handiwork also challenges definitions in archaeology: Is the rock fragment an artifact? By definition that’s an object created by humans. Since the monkey wasn’t observed using the rock fragment in any manner, is it a tool? For our story, see page 9.

  • Evaluating Claims for an Early Peopling Of
    Evaluating claims for an early peopling of the Americas: experimental design and the Cerutti Mastodon site Matthew Magnani1,*, Dalyn Grindle1, Sarah Loomis1, Alexander M. Kim1,2, Vera Egbers1,3, Jon Clindaniel1, Alexis Hartford1, Eric Johnson1, Sadie Weber1 & Wade Campbell1 In a 2017 article, Holen and colleagues reported evidence for a 130 000-year-old archaeological site in California. Acceptance of the site would overturn current understand- ing of global human migrations. The authors here consider Holen et al.’s conclusions through critical evaluation of their replicative experi- ments. Drawing on best practice in experimen- tal archaeology, and paying particular attention to the authors’ chain of inference, Magnani et al. suggest that to argue convin- cingly for an early human presence at the Cer- utti Mastodon site, Holen et al. must improve their analogical foundations, test alternative hypotheses, increase experimental control and quantify their results.

  • Cerutti Mastodon Site Story of the Discovery
    UNDER EMBARGO UNTIL WEDNESDAY, APRIL 26 AT 10 AM PDT Cerutti Mastodon Site Story of the Discovery “It looks like an archaeological site.” “It can’t be an archaeological site.” In November 1992, the California Department of Transportation (Caltrans) was doing highway construction on State Route (SR) 54, where San Diego borders National City. Paleontologists from the San Diego Natural History Museum’s PaleoServices Department were conducting routine monitoring of grading activities to identify any fossil material that might be exposed when field paleontologist Richard Cerutti spotted what appeared to be bones and tusk of a fossil mammoth. Immediately, construction in the immediate vicinity of the discovery was halted. As Cerutti explored the site with PaleoServices Director Dr. Tom Deméré and their team, they found fragments of distinctive molars revealing that what they were actually looking at was a fossil mastodon, a relative of mammoths that lived in this region and went extinct around 13,000 years ago. But something was puzzling. Many of the bones were strangely fractured—or missing entirely. And there were several large stones found in the same sediment layer as the bones and teeth that appeared out of place. It looked like an archaeological site—like the preserved evidence of human activity. But it couldn’t be an archaeological site. At that time, the oldest evidence of hominins (humans and related species) living in North America came from sites that were approximately 14,000 years old. But as the paleontologists would determine over weeks of excavating the site, the mastodon bones and teeth lay embedded in fine-grained sediments that had been deposited much earlier, during a period long before humans were thought to have arrived on the continent.
