FJD UTAH 31. Henry Mountains. Jurassic; Morrison formation. Utah and Colorado fossil wood hunters normally call this a full round, although it’s a portion of a larger tree, as is obvious from the growth rings. The exterior is consistent all around. Subdued reds and shades of gray ringed with the red-amber rind comprise the well-balanced face. It’s a. specimen round, cut and polished on one end, otherwise as found. The state of preservation is remarkable with mostly indistinct cell structures. No glue or filler. 9 by 7 cm mirror-polished face; up to five cm thick; fifteen ounces. $115
Note: I hear many names for the outer portion of a wood specimen – most often I hear bark, which is least often what it is. I hear cortex in its geological sense, but since there’s already a botanical definition for cortex meaning bark, I don’t believe we should employ the geologic term of cortex for fossil wood. I usually call it the exterior unless it’s actually bark or cambium layer.
