I wondered about that but then in context wasn’t sure of the relevance. I’m aware that even fresh eggs are somewhat porous and wouldn’t expect the contents to last beyond a week before beginning to break down.
The eggshell looks like a century egg, but as mentioned by the comment the contents may have decomposed if the mud wasn't alkaline like the century egg production process.
It might be the only 1700 year old egg in the world. Surely the prudent thing to do is wait some fraction of its age (200 years?) and reevaluate. What are the chances that, out of all of history, now is the best time to open it?
> A Micro CT scan showed that this ancient egg is still full of liquid.

I think it is a mistake not to cut the top off the egg and just look inside as ancient egg shell has no value after it drys out and the visual information may be unique,so off with its top, and
then take samples of the "liquid" and the inner shell lining, if it's present, and then see if there is any remaining structure of an embryo or the egg as laid.
This is actually my wife's job/area of research, except typically they use the eggshell proteins to determine taxonomy. It's extremely rare that DNA survives in these types of samples but the proteins are preserved in the eggshell's mineral matrix.
It's usually just called archaeology or perhaps biomolecular archaeology. Forensic archaeology is a bit different, and it usually pertains to humans and their crimes.
Egg shells are more organic than you expect.
This is why you use stuff like waterglass https://en.m.wikipedia.org/wiki/Sodium_silicate to seal them.
