Jurassic fossil plants of Makhtesh Ramon, the northern Negev, are collected from the Early Bajocian paralic Inmar Formation conformably overlain with the marine Mahmal Formation, which contains ammonite markers of the Middle–Upper Bajocian age. Pla

In India, potential sources of angiosperm macrofossils are the intertrappean cherts of Rajmahal Hills, palynologically and radiometrically dated as Barremian–Aptian. However, our revision of the previously reported flower-like and fruit-like fossil

We report on the first find of peltasperms in the Permian of Gondwana. Well-preserved leaf compressions and reproductive structures of these plants came from the Lower Permian Barakar Formation of Satpura Basin, central India, where they co-occur wit

New plant macrofossil localities are found in the middle-upper part of the Albian Upper Hatira Formation of Makhtesh Qatan, an erosion crater in the northern Negev. These are so far the only outcrop localities in the Negev containing plant compressio

A provisionary system of gnetophytes is proposed, including recently discovered Mesozoic members. The following principal characters are used, in descending order of significance: strobilar structure of ovulate organs (eugnetophytes) as opposed to fl

A considerable disparity of pollen characters in the modern Gnetales (including the inaperturate and monosulcate germination types, the psilate, polyplicate and spinulose sculptural types) stands in sharp contrast with their ultrastructural uniformit

Temporary mining is a peculiar behavioral trait in leaf parasites requiring adaptations of consecutive larval stages to the endophytic and ectophytic life. The first fossil evidence for the origin of the trait comes from the Cretaceous (Turonian) pla
