| Palaeoaldrovanda splendens Knobloch & Mai (1984) |
Palaeoaldrovanda splendens is an extinct species of carnivorous plant. It is thought to be the evolutionary ancestor of species in the genus Aldrovanda.
P. splendens is only known from seed fragments found in the late Turonian-Santonian Klikov beds of the Czech Republic.[1][2] They represent the second oldest known remains of a carnivorous plant, after Archaeamphora longicervia, a pitcher plant from the Early Cretaceous.
Anderson et al. (2005) note that "synapomorphic characters that link the fossils seeds [of P. splendens] to extant Aldrovanda include hard testa with an outer epidermis of palisade cells and with a smooth, strongly reflecting surface, short micropylar neck, and extruding, pointed chalazal area".[3]
