A praying mantis preserved in amber for millions of years not a sculpture, but a real prehistoric insect trapped in tree resin and fossilized into a natural time capsule.
An entire moment from ancient Earth… frozen before humans even existed.

The premise is wrong, though. Resin tends to be acidic. You know what doesn’t like acid treatment? Chitin, on account of being a polysaccharide.
And even - or especially - if the resin was perfectly neutral, it would slowly suck the fats stored in the insect’s tissues out of the same.
Plus the O2 that’s slowly diffusing in - and out - of the resin will, especially in connection with sunlight, decompose more and more stuff.
Whatever the decomposition processes are, you can see an orange-tinted sort of halo around the mantis. That’s the mixing zone - mantis molecules, meet resin molecules.
