From the article
Your full quote provides the important context included in the original statement, “most important…to be found in Britain”.
Is it more important than the 30,000+ yo mammoth carving recently found in Swabia? Debatable, but the article never claimed it was contending for such a designation.
I'd wager a hard no.
I would wager that the discoveries at Narwala Gabarnmang are among the most important - to the rest of the human species - of all the pre-historic art currently under the gaze of the archeologists eye ..
