Yellow Cat Petrified Wood comes from Grand County, Utah found in the Brushy Basin Member in the Morrison Formation. This petrified wood is about 140 million years old from the Jurassic Time Period. Yellow Cat Petrified Wood is extremely rare and highly prized by wood collectors and rare specimen collectors alike.  The limb casts from this area can be solid banded agate all the way through, banded agate with calcite or quartz centers but the majority are partial replacements with the banded agate mixed with permineralized wood to complete the casts. The agate colors range from red, orange, black and yellow. The black and red fortification wood is very rare.
