    Post Extinct CP

    Archaeamphora longicervia is an extinct species of pitcher plant, fossils of which were discovered recently China. The wild thing about it is that its placement in the fossil record indicates that Archaeamphora it is one of the three oldest genera of Angiosperms known! Li, who published the specis in 2005 noted 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".

    Read more about it here. From the artist's rendition you can see that it bears similarities to Sarracenia purpurea. Pretty cool, huh?

    Very cool. Thanks for sharing this. While it's cool for us as CPers, it's also interesting in general because of the extrapolations being made.

    What a fascinating discovery! It's so small, when I first read your notice I imagined a "prehistoric sized" pitcher plant that could eat a horse. Now all we need is a discovery of a living specimen, Coelacanth-style. I also learned of the species designation of H. exappendiculata from the attached Wikipedia article. Two new species learned in one day!

    280 mya is completely nuts- that would be near the begining of all seed plants. Many older seed plants diverged later, so that is incorrect. The closest current estimate is in the late triassic
    that makes no logic

    I think that Li was saying that the closest current estimates were WRONG, and that having such a highly derived plant show up in the early Cretaceous indicates that angiosperms must have existed for quite some time by then. 280 mya could be a high figure - I really not an expert in this area - but the it makes sense to me that the date for angiosperm development would be pushed back by this kind of discovery.

    Holy crap! Just saw the artist's rendition and I was really surprised. I'm grateful the modern Sarracenia don't look that last beast.
