An incredible 99-million-year-old chunk of amber contains several trapped marine gastropods, including an extinct ammonite, according to a new paper.
Amber is fossilized tree resin, and occasionally it preserves bits of plant and animal matter, like insects and bird feathers. But in this case, scientists from China, the United Kingdom, and the United States uncovered a rare example of marine animals trapped in amber. Not only is it exciting to find the shell of an ammonite—an extinct mollusk usually only seen as an imprint in rock—but it also offers scientists another way to establish when the amber was created.
