Boavus Boavus is an extinct genus of boa known primarily from Eocene-aged strata of North America. At least three species ("B. occidentalis, B. idelmani", and possibly "B. agilis") are known from the Middle Eocene Green River lagerstätte in Wyoming, two species from Eocene strata of Uinta County ("B. occidentalis" again, "B. brevis"), and at least one species is known from the middle to late Eocene-aged Sepse Formation of California ("B. affinis").
