"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-SantonianKlikov beds of the Czech Republic. [Knobloch, E. & D.H. Mai 1984. Neue Gattungen nach Früchten and Samen aus dem Cenoman bis Maastricht (Kreide) von Mitteleuropa. "Feddes Repert. (Berlin)" 95: 3-41.] [Knobloch, E. & D.H. Mai 1986. Monographie der Früchte und Samen in der Kreide von Mitteleuropa. "Rozpravy ústredního ústavu geologickénho Praha" 47: 1–219.] 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".

"American Journal of Botany" 92(10): 1737–1748.]
