Some of the wild Australian carpets I've seen while browsing social media and iNaturalist look... not always ancient, but definitely very weathered. Many are "ancient snake" large, and more than a few have big old heads and scarring from big prey. It's amazing how tough these snakes can be and how long they can last.
I'd be lying if I said that looking at those wild carpets hasn't left me wanting another, haha. Some of those wild carpets are gorgeous. It would be cool to have Morelia from both ends of the genus' distribution, ie. Pandora and a more southerly coastal or diamond.
