Ancient Copper and Silver Assyrian, Egyptian, or Babylonian Plate

This plate looks as though it is very ancient maybe of Assyrian, Egyptian, or Babylonian decent. It has what appears to be three men fighting or trying to kill an unknown animal with a horn of some sort on top of its head and a cherubim in the sky above pointing upward... there are also some depictions of maybe a flowering plant native to the area that it was made in? The intricacy of the detail in its artwork and craftsmanship are incredible. It has no insignia, hallmark, or any kind of signature from its creator either???? Please help me figure out what it is that I’ve found!

Good
