Yes, Virginia, there is a Neanderthal fossil record in America. And apparently a Neanderthal hybrid fossil record.
No genetics publication has put all the evidence together: the genetics establishment is still in denial about most things Neanderthal. The evidence is scattered and mostly unrecognized, but, in our opinion, conclusive and compulsive. Consider the following article:
The mental foramen (literally "mind's little hole") is an anatomical trait very pronounced in Neanderthals, a small dimple in the lower jaw of the skull beneath the teeth, or mandible. It is found sporadically in humans, where it is classified as archaic. Among the places where it has been identified are the Oleniy Islands and Baltic region, Northwestern Russia in Cro-Magnon like Europoid and Mongoloid types, along with "large and massive" torus occipitalis or Anatolian bumps (Alexander Mongait, 1959; Marija Gimbutas, 1956); Bakhehisarai in the Crimea (Alexander Mongait, 1959); the Joman or Ainu of Japan (Carleton Stevens Coon, 1962); and the "race of giants" continually being unearthed in West Coast, Ohio Valley and New England archeological sites, caves and mounds.
Archaic giant skeletons with mental foramina, occipital bumps, double rows of teeth and other Neanderthal features are reported, in fact, all over the Americas. Fritz Zimmerman has gathered a lot of the evidence in a new book titled Nephilim Chronicles, of which a small excerpt was published in Ancient American magazine, issue 91, pp. 24-27. Here is one of the newspaper reports he cites:
Evening News (Ada, Oklahoma), November 8, 1912. PRIMITIVE MEN OF GIGANTIC STATURE.
Eleven skeletons of primitive men, with foreheads sloping directly back from the eyes and two rows of teeth in the front of the upper jaw, have been uncovered at Craigshill at Ellensburg, Washington. They were found about twenty feet below the surface, twenty feet back from the face of the slope, in a cement rock formation over which was a layer of shale. The rock was perfectly dry. The jawbones, which easily break, are so large that they will go around the face of a man today. The other bones are also much larger than those of the ordinary man. The femur is twenty inches long, indicating a man of eighty inches tall [6' 8"]. The teeth in front are worn almost down to the jawbones, due, it is believed, to eating uncooked foods and crushing substances with the teeth. The sloping skull shows an extreme low order of intelligence.
We note that the female mummy clutching a child known as The Thing on display at a roadside attraction on Interstate 10 north of Tombstone, Arizona, has a double row of teeth. It supposedly was one of three skeletons sold to the operator of the original site for $50 by a Chinese gentleman passing through. The Thing is discussed in several works by David Hatcher Childress. (My son and I paid our two bucks and saw it last Christmas on a road trip.)
