Yes, they exist! Here are three incredible examples of insects entombed in amber that showcase fossilized farts. These insects were trapped in tree resin and died 34-48 million years ago during the Eocene Epoch. Prior or post death, these insects all released gas which was captured as a bubble in the resin. That tree resin then fossilized. These specimens are all from the shores of the Baltic Sea of Lithuania.
