Cretaceous angiosperms

left|thumb|Fossil cast of A. liaoningensis Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now understood to be approximately 125 million years old, or early Cretaceous in age. Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants. thumb Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are

Archaeamphora longicervia is a fossil plant species, the only member of the hypothetical genus Archaeamphora. Fossil material assigned to this taxon originates from the Yixian Formation of northeastern China, dated to the Early Cretaceous (around ).

Montsechia is an extinct genus of aquatic plants containing the species Montsechia vidalii, described from Spain. M. vidalii lived about 130 million years ago, during the Barremian age, and appears to be the earliest known flowering plant macrofossil. It has affinities with the modern genus Ceratophyllum. It has been placed in the ceratophyllalean family Montsechiaceae.
