Archaeanthus

Archaeanthus is an early angiosperm described from the mid-Cretaceous (uppermost Albian to mid-Cenomanian) Dakota Formation of central Kansas, USA. Archaeanthus linnenbergeri Dilcher and Crane is a multifollicular angiosperm fruit. It is linked with perianth parts (Archaepetala beekeri Dilcher and Crane and Archaepetala obscura Dilcher and Crane), bud scales (Kalymmanthus walkeri Dilcher and Crane), and leaves (Liriophyllum kansense Dilcher and Crane) on the basis of association evidence and structural agreement in the presence of distinctive resin bodies (Dilcher and Crane, 1984).
