Archaeocyatha (meaning "ancient cups") is an extinct group of vase-shaped marine sponges that built the planet's very first animal reefs.Thriving during the Early Cambrian Period roughly 525 to 510 million years ago, these organisms played a critical evolutionary role. They stepped up as the world's primary reef builders right as Earth's atmosphere and oceans experienced a massive surge in oxygen levels.
