The bat is largely mummified but adamite has started to replace around its face - fluorescent light highlights the adamite.
Found by John Seibel, late 1980s at the Gold Hill Mine, Utah, collection of Mark Mitterman.

Jack Hills zircons have been dated to ~4.4 billion years ago. They were formed during the Hadean (all of earth was more-or-less molten), then cycled into sedimentary grains. #MinCup #TeamZircon
