the youngest haramiyid fossil genus is "avashishta bacharamensis" from the maastrichtian of india. cretaceous haramiyids are previously known from the early cretaceous of morocco, suggesting that these animals may have survived in gondwannan landmasses as relics; the presence of the similarly aged "cifelliodon" in north america suggests that contact between both landmasses remained for a while. with a temporal range of at least 150 million years, they are the longest lived mammaliaform lineage.
