Kinda hard to spot sometimes:   Palm shrinkwood rough:  Easier to spot shrinkwood showing some pattern:  Big hunk of just flat colorful shrinkwood:  |

Awesome! That snakewood is double awesome!
Curt
Does the color in the Snakewood have the Snakewood pattern or is it completely replaced?

Yeah Curt, the pattern extends clear across the face of the piece. The color in this wood from this guys collection is really strange sometimes and occurs kind of in veils and swirls where the iron salts must've flowed in from old fractures before healing. Man it is frustrating not being able to ID many of these types. Got several odd palm types this time and also another of those pocket rot type specimens. Really fun to hunt these piles as you just don't now what you'll stumble across next.....Mel

Whoa, second set. You came away with quite a haul. Sorry for the ignorance on the shrinkwood but how does it end up with that patterning? Almost gives it a stained glass sort of appearance.

Mel, you have a treasure trove there. The hexagonal fractured wood needs to be polished as specimens. The snakewood is a hard find and color in it is just downright rare. If you need help with face polishing some of it, give me a holler and I'll be glad to help.

Paul: The theory is that the wood at some point was stress fractured and then later resealed just like you'd see in a brecciated jasper like Stone Canyon. Most of it was in some state of decomposition before petrification too which accounts for the total lack of woodgrain or vascular patterns in some or scattered blocks of pattern in others. The high level of secondary mineralization with silica also destroyed much of the original wood pattern. A good many of the specimens from this area ( Live Oak County and surrounding counties in south Texas) would probably be classified as wood casts too, as in those specimens, most all wood grain pattern is lost and many appear to be solid agate, mainly in the moss agate category. If you Google hexagonal fracturing in petrified wood, you'll find several good articles with some great pictures....Mel
