L Alvin. These sediments contain fossil leaf fragments of ferns and angiosperms that grew close to the lake. The occurrence of the Mesozoic fern Weichselia reticulata is of importance.

This discovery suggests the survival of this Jurassic to Cretaceous fern into the early Paleogene in the refugial geothermal ecosystem of the Boltysh crater area.

Soral clusters of Weichselia reticulata, exposed by opencasting near the village of Escucha, province of Teruel (Aragon, Spain) in the Albian Escucha Formation, provide new information on the.

Weichselia reticulata remains are common at certain levels of the Escucha Formation in its type area. Fragments of fronds showing pinnae of the first order and numerous second order pinnae are quite common, and, at certain levels isolated indusia are by: New reconstruction of Weichselia reticulata (Stokes et Webb) Fontaine in Ward emend.

Remains of conifers belonging to the genera Mesembrioxylon and Brachyphyllum have also been reported, but the family affinities of these is Weichselia reticulata book unclear (Edwards, ). Portions of leaves resembling members. Weichselia reticulata (C. Stokes et Webb) Fontaine was first described from the English Wealden as Pecopteris reticulata by Stokes and Webb (), the generic name being later changed to Weichselia reticulata by Fontaine ().

This fern has drawn attention due to Cited by: 2. Evidence of fertile remains of Weichselia reticulata is very scarce worldwide. Soral clusters connected to their last order rachises have been found in Hauterivian -Barremian deposits from Germany.

The taxon Paradoxopteris stromeri Hirmer, representing the rachis/petiole/stem of the fern Weichselia reticulata (Stokes et Webb) Fontaine, has a widespread occurrence in the Early–early Late Cretaceous of Northern Africa and the Near East, Europe, as well as South America.

The Bikfaya reference section is located in central Lebanon, ca. 35 km due ENE of Beirut, at 33°55’20”N, 35°42’40”E (Fig. 1).The section is reached by traveling from Beirut to Antilyas on the Beirut-Juniyah coast road, and then eastward on the Antilyas-Bikfaya road.

Przenosza (Western Carpathians, Poland) is an important palaeobotanical Cretaceous basement site with morphologically well-preserved plant remains.

Both the morphology of the macro remains and microscopic examination of isolated plant cuticles reveal species typical of coastal swampy palaeoenvironments, mainly the fern Weichselia by: 7. References about Weichselia reticulata in Spain consist of remains of vegetative primary and secondary pinnae and also pinnules and isolated indusia overall in laminated and carbonated lacustrine.

The Paleocene oil shales from the Boltysh crater are also enriched with macrofossils of ferns, especially a xerophytic Cretaceous relic Weichselia reticulata and shrubby angiosperms: Salix, Myrica.

The data provide evidence for the repeated occurrence of palaeo-wildfires in coastal ecosystems on the northern margin of Gondwana during the Barremian. The fossil content of the lens indicates that the vegetation, which was repeatedly affected by fire, has been dominated by the matoniaceous tree fern Weichselia reticulata.

These include fern leaves (Weichselia reticulata), as well as fossil wood, roots and leaves believed to be those of a gymnosperm conifer tree of the Araucariacea family related to the large pine trees of the genus Agathis still existing in the Southern Hemisphere.

After becoming nearly extinct during the Permian, the ferns began a slow recovery during the Triassic as the climate of the earth moderated.

As a result, a considerable number and variety were present and widely distributed during the Jurassic and Early Cretaceous. However, with the rapid expansion of the angiosperms during the Late Cretaceous, the ferns once again became reduced in Cited by: The Bahariya Formation (also transcribed as Baharija Formation) is a fossiliferous geologic formation dating back to the Early Cenomanian, which outcrops within the Bahariya depression in Egypt, and is known from oil exploration drilling across much of the Western Desert Overlies: Basement.
