Our featured specimen

Agate cast of trunk/root collar/emanating roots
Humboldt Formation; Middle Miocene
Texas Springs (near Jackpot), Nevada
** This is NOT your classic pink limb or root cast from the Texas Springs locality.  One seldom knows where the particular specimen was located on a living tree but this specimen leaves nothing to doubt.  There are a couple of inches of trunk, then a root collar, and then emanating rootlets from the basal portion of the trunk.  In other words, the center of this section (the root collar) was at ground level with trunk above and roots below.   It is definitely one of the most interesting agate cast specimens from this classic locality that we have ever seen.  If you are interested in the morphology of trees - this is a perfect fit for your collection.  It could serve as an outstanding teaching example as well as an attractive display specimen.  
Dome polished face approximately 2" x 1.5"  Total section length is 5"    $85

Elm  (Ulmus sp.)
Trout Creek Formation, Miocene
Zimmerman Ranch at the McDermitt diggings, Oregon/Nevada
**  What a great display limb section.  We simply love these specimens showing heart rot and this one has the extra added advantage of having some differential erosion within the cavity that highlights the annual growth ring development.  Additionally, the specimen has really excellent preservation of woody fine structure (see the accompanying photomicrograph).  One of the clues to identifying elm is the chevrons (V-shapes) of the tiny pore groups in the summer wood after a nice array of larger pores on at the beginning of the growth ring (the spring wood). This specimen really shows that feature off perfectly!  It also has wonderful external woody character. 
3" diameter on the polished end face; 1" x 1.5" on the polished face; 4" long limb section   $49

​Conifer (Pinales Order)
Little Butte Formation, Mehama volcanics unit, Oligocene
McQueen Ranch, Sweet Home area, Linn County, Oregon
**  BULLS EYE!  Just check out the fantastic growth rings on this beauty.  They are closely spaced, exceptionally narrow and perfectly round.  Just the kind of slab that a favorite collector friend of ours calls a target-like bulls eye.  We agree - this one is really fabulous.  The McQueen Ranch has not produced petrified wood for quite a long time, but a recent logging operation and the attendant soil disruption has produced some really nice specimens and we thing we got some of the best!  The ranch is directly across the road from the famed Holleywood Ranch which has consistently produced enormous amounts of petrified wood, but the two neighboring sites could not be more different in mineralization.  While the Holleywood site has produced mainly tan to rust colored specimens, the material found recently at the McQueen is quite dark.  When the logging operation is complete and the trees begin to regrow, there won't be any more petrified wood discovered for a considerable period of time.  So, if you like the perfection of growth rings produced by this great slab, we suggest you acquire a specimen for your own collection before it is all gone - we did!

​Oak (Quercus sp.)
Columbia Plateau Basalts Group, Miocene
Deschutes Canyon, Oregon
**  A VERY nice thin slab of oak from this legendary locality.  Please don't worry about the lack of thickness, because this special slab is professionally backed with fiberglass and is therefore very stable.  The site was on top of the canyon walls about four miles upstream of the confluence of the Deschutes River and the Columbia River.  In recent years, the ranchers who own the land on the sides of the canyon walls have closed their property to collecting.  As a consequence, this especially nice material has now become much more difficult to obtain.  This particular specimen came out of the inventory of a Deschutes Canyon local cutter who (decades ago) cut very thin slices off of logs in order to make coffee tables (the slabs would be placed on a circular jig and covered with clear resin).  We were fortunate to get some of his unused inventory (especially since most of the resin in the coffee tables has become discolored over the past 40 years and the tables discarded)!   This specimen has the extraordinary characteristics that make Deschutes Canyon material desirable -- good eye appeal with a nice definition of medullary rays, and perfectly round.  Click photo for a closer view ... and then don't let this one get away!  We can't call it rare, but it is surely less abundant in the market now.
