FOSSIL WOOD. Early Jurassic. Lune River, Tasmania. 40x80x95mm (F190)
A polished section of complete trunk of a conifer with some attached matrix of volcanic sediment. This unusual section shows an interruption to the growth, perhaps by a fire event with subsequent healing of the wood. Shows detail of growth rings, tracheids and agatised pith. Underside has been cut but not polished.
