The Mysterious Origins of Man
narrated by Charleton Heston

Kuban states: "The hammer, reportedly from a paleozoic formation near London, Texas, is encased in a concretion and thus may be unrelated to the age of the host rock (Godfrey and Cole, 1985, p. 46)."

The lithology or rock type containing the hammer is visually and texturally similar to the lithologies found at Glen Rose.  In addition, the wooden handle appears to be petrified (possibly silicified) based on how it fractured along joints just below the metal hammer head.  Although concretions such as this can form rapidly, petrification of wood takes many thousands of years - placing the artifact well before humankind's industrial revolution.  Joints or linear fractures commonly form in rocks, and are typical of silicified wood.  Concretions frequently form around foreign objects as sediment is transformed to rock with gradual burial and sedimentary compaction.  Concretions are the reason why many excellent fossils are preserved.  According to Baugh in The Mysterious Origins of Man an analysis of the metal in the hammer head yielded an exotic alloy presumably unknown to modern man (and therefore presumably not known to historical man).  However, results of his analysis have not been published on Baugh's website, nor were they provided on the video.  If further examination of this fossil shows that the lithology of the concretion is like that found in the Glen Rose Formation, and that the metal is indeed that of an unknown alloy, its dismissal by Kuban would be premature.
