GGG is not contesting whether or not it was fossilized. That it was is obvious. However, How is tissue ‘millions’ of years old, still fresh enough to have softer organic parts still intact? Fossilization has been shown that it can be a rapid process.
THAT is the basis here. Having sofetr tissue still intact is the key.
Sorry, but GGG´s contention is *indeed* that it wasn´t fossilized. It´s central to his conceit.
