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 143 to 101 million years ago).[1]
The species was originally described as a pitcher plant with close affinities to extant members of the family Sarraceniaceae. This would make it the earliest known carnivorous plant and the only known fossil record of Sarraceniaceae, or the New World pitcher plant family.[2][3][4][5] Archaeamphora is also one of the three oldest known genera of angiosperms (flowering plants). Li (2005) wrote 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".[1]
Subsequent authors have questioned the identification of Archaeamphora as a pitcher plant and a taxon of angiosperm at all.[6][7][8] The fossils more probably represent leaves (needles) of the coniferous Liaoningocladus boii deformed by insect galls.[9]
