Help with Ancient(hopefully) Chinese jar

Hello all
)Just won the bid on this elephant jar that I have never seen before. Image Google bring up a few and many variations animals but all are bronze, as this is not. Could be a repo but if so not a lot being made like this at all. In pre research I did find this link which only has an exact diagram(4th image down):

That website was blocked because of a Trojan horse infection, so you'd better run your anti-malware program.
And please delete the link.

 

Is it ceramic?
It seems to be a copy of a Western Zhou ritual wine vessel. Like this bronze one:

That overall black staining gives me pause .

@Any Jewelry , Never mind, got it. Just takes a while to sink in. Found it

 

Because it doesn't look like Zhou ceramics.

The Western Zhou dynasty was 1046-771 BCE. It would probably have been too complicated to make a ceramic elephant shaped vessel that would survive the firing process.

The wiki page doesn't specify Zhou period ceramic zuns, just that during the entire period of zun making, ceramic zuns were made. They could have been made long after the Zhou period, for instance during the Song dynasty.

 

That's OK, it can take a while to adjust to a new concept.
