Description:
Aphlebia
Presl 1838
-
is still unknown and very mystery fossil plant, found
in paleobiological - paleoecological interaction with Carboniferous " true" spore ferns like Pecopteris.
Aphlebia
is normally connected along the main axis of the fern fronds and has a variety of irregular and pinnatifid leaves which display incomplete to poorly visible veins that are typically parallel.
Recently group of scientists announced , that found Aphlebia
reproductive structures preserved and documented in compression-impression material. These structures resemble sporangia which are typical of the Carboniferous ferns. These new records indicate that Late Carboniferous Aphlebia may have developed an autonomous !
Aphlebia shapeless -
irregular leaflets growing on the stem of some ferns . They occur mostly detached. To this day we don't know why Aphlebia grew on the paleozoic ferns stems. Maybe Aphlebia protect delicate, curled, juvenile fern leaves ( so-called Spiropteris) by insects or it was a parasitic plant - a fern like Platycerium or like mistletoe - that grow in treetops ?
