Asha and Baz travel in time to unearth fossils! When their teacher assigns The Great Fossil Challenge, best friends Asha and Baz wonder how they'll convincingly re-create a prehistoric fossil. Luckily time is on their side! Together, they magically travel to 1823 to meet legendary fossil hunter Mary Anning, who shows them the marine fossil beds along the cliffs of the English Channel. Ammonites, evidence of marine reptiles, and more wait just beneath the earth's surface, and with Mary's instructions, the kids might uncover the exact inspiration they need to succeed back at home!
