Archaeamphora longicervia is an extinct species of pitcher plant bearing close affinities to extant members of the family Sarraceniaceae. Fossil material assigned to this taxon originates from the Yixian Formation of northeastern China, dated to the Early Cretaceous (around 146 to 100 million years ago).
Archaeamphora longicervia is the earliest known carnivorous plant and represents the only fossil record of pitcher plants (with the possible exception of some palynomorphs of uncertain nepenthacean affinity). Furthermore, the monotypic Archaeamphora is one of the three oldest known genera of angiosperms (flowering plants). Li (2005) notes that "the existence of a so highly derived Angiosperm in the Early Cretaceous suggests that Angiosperms should have originated much earlier, maybe back to 280 mya as the molecular clock studies suggested".
The area inhabited by A. longicervia is thought to have experienced significant climatic fluctuations during the Early Cretaceous, ranging from arid or semi-arid to more humid conditions. The substrate in the region was mostly composed of lacustrine sediments and volcanic rocks.
