Cladophlebis is an extinct form genus of fern, used to refer to Paleozoic and Mesozoic fern leaves that have "fern fronds with pinnules that are attached to the rachis, and have a median vein that runs to the apex of the pinnule, and veins from that are curved and dichotomise". By convention this genus is not used to refer to fossil ferns from the Cenozoic. Ferns with this morphology belong to several families, including Osmundaceae, Dicksoniaceae and Schizaeaceae.[1] Ferns with this morphology are common during the Paleozoic and Mesozoic in both the northern and southern hemispheres.[2]
Species
There were many species of Cladophlebis, including: C. akhtashensis, C. arctica, C. browniana, C. denticulata, C. dunberi, C. haiburnensis, C. heterophylla, C. hirta, C. impressa, C. kurtzi, C. lobifolia, C. nebbensis, C. patagonica, C. phlebopteris, C. porsildi, C. readi, C. remota, C. retallackii, C. roessertii, C. septentrionalis, C. simplicima, C. spectabilis, C. tenuis, C. wyomingensis, and C. yanschinii.
Distribution
Fossils of Cladophlebis have been found in many locations around the world, among others in the Valle Alto Formation of Caldas and the Caballos Formation of Tolima, Colombia,[4] and the Winton Formation, Eromanga Basin, Queensland, Australia.[5]
