Sanmiguelia is an extinct plant genus, probably of flowering plants. The genus and the species Sanmiguelia lewisii were first described in 1956 from the Late Triassic Chinle Formation in Colorado,[5][6] and later in Lower Jurassic Moenave Formation in Utah.[7][1] The species has been suggested to be one of the more primitive angiosperm fossils.[8]
