A new genus Konijnenburgia is introduced for fertile, well preserved ferns of the family Matoniaceae, which were previously assigned to the genus Nathorstia Heer. 1. Introduction Mesozoic environments and concepts of fern ecology. The Mesozoic was an era of warm climate. Absence of polar icecaps and probably even belts of cold climate is indicated by finds of thermophilic plant remains in the Arctic and Antarctic (Vakhrameev, ).After the recovery during the Early Triassic from the dramatic climatic changes and mass extinctions around the Permo Cited by: The present fossil locality is in Zigui County, western Hubei, the eastern part of the Three Gorges Area of the Yangtze River. This area is tectonically located in the southeastern marginal region of the ancient Yangtze Plate, along the north coast of the Tethys Ocean (Wang et al., ).The Jurassic strata are well developed in western Hubei, attaining a maximum thickness of m and are Cited by:

Schizaceae The origin of this family probably lies in the Jurassic. Klukia (right) is a rather common formgenus within this group. The climbing fern Lygodium, which has nowadays leaves without blades up to 10 m long, is also a member of this photo on the left shows a part of a leaf of Lygodium gaudinii from the Oligocene of the south of France (30 million year).   During the Jurassic, Sardinia was close to continental Europe. Emerged lands started from a single island forming in time a progressively sinking archipelago. This complex palaeogeographic situation gave origin to a diverse landscape with a variety of habitats. Collection- and literature-based palaeobotanical, palynological and lithofacies studies were carried out on the Genna Selole Formation Cited by: 6. Dryopteris / d r aɪ ˈ ɒ p t ə r ɪ s /, commonly called the wood ferns, male ferns (referring in particular to Dryopteris filix-mas), or buckler ferns, is a fern genus in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of (PPG I). There are about species in the genus. The species are distributed in Asia, the Class: Polypodiopsida. Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to Cyathea, but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores.. The genus contains 20–25 species, distributed from Mexico to Argentina, Brazil, Uruguay and Chile, St. Helena, New Zealand, New Class: Polypodiopsida.

Polystichum braunii is easy to recognize in Wisconsin. The dark green, shiny blades are 2-pinnate, conspicuously narrowed to the base and often evergreen. It is similar to P. acrostichoides in the presence of basal auricles on some of the pinnae and in the spiny-toothed margins of the pinnae. It differs in that the sterile and fertile fronds are similar, and the sori are distinct and separate. A visit by the Yorkshire Geologists is recorded and a distinguished visitor was Professor st, geologist, paleobotanist and arctic explorer from the Swedish Natural History Museum, Stockholm. Particular fossils were sent for identification to Mr , author of The Jurassic Flora of Yorkshire and later to become Professor SirFile Size: KB. The Steven Spielberg movie "Jurassic Park" based on the best-selling novel by Michael Crichton, offers a realistic and terrifying look at some of the incredible animals that once roamed the earth during the Cretaceous and Jurassic Periods ( million years ago).In the story, scientists isolate dinosaur DNA from the stomachs of blood-sucking insects preserved in amber.
