Paleontological Sites of Lebanon - Wikipedia, the Free Encyclopedia Page 1 Paleontological sites of Lebanon - Wikipedia, the free encyclopedia Page 1 Paleontological sites of Lebanon From Wikipedia, the free encyclopedia The paleontological sites of Lebanon contain deposits of some of the best- preserved fossils in the world, and include some species found nowhere else. The most famous of these is the Lebanese lagerstätten of the Late Cretaceous age, which contain a well-preserved variety of different fossils. Some fossils date back to the Jurassic period, and younger fossils of mammals from a different site belong to the Miocene through the Pleistocene. The fossils found in Lebanon are displayed in natural history, geology and paleontology museums around the world.

(lobster, left), Diplomystus birdii (fish, 5 References right), and a partial Dercetis triqueter , Cretaceous Hakel, Lebanon 6 External links History The earliest known account of Lebanese fossils is attributed to Herodotus.[1][2] The existence of fossil fishes in the Lebanon is referred to by Jean de Joinville. In his Histoire de Saint Louis he wrote that during the sojourn of King Louis IX of France at Sidon in 1253, just before his return home from the Seventh Crusade, a stone was brought him, which was the most marvellous in the world, for when a layer of it was lifted, there was found between the two pieces the form of a “ fish. The fish was of stone, but lacked nothing in form, eyes, bones, colour, or anything necessary to a living fish.[3] ” European scientists became interested in Lebanese fossils in the 19th century.[1] Locations and fossils There are three major fossil locations in Lebanon: Sahel Alma, Hajula and Hakel. Hajula and Hakel are each about twelve miles north-east of the coastal town of Jebeil, the ancient Byblos. Hajula is situated six miles south of Hakel; and between the two villages there are two westward-projecting spurs of Mount Lebanon and an intervening valley. Both villages are approximately 2500–3000 feet above sea level. In both places there is clear evidence of faulting by which the fish-bearing strata have been lowered into the midst of older strata. Those at Hakel have been lowered to the level of the hippurite limestone of Lebanon, being above the trigonia sandstone. The Hajula beds are thought to be an extension of those at Hakel. The study of fish fossils appears to show that the horizon of the beds at Hajula is somewhat higher than that of the beds at Hakel.[4] Rhinobatos whitfieldi , a species from the Cretaceous period found in Lebanon The fishes found at Sahel Alma mostly belong to the same genera as those at Hakel and Hajula, but of around sixty species, probably not one is found elsewhere. Twenty-one species found at Hajula also occur at Hakel. These data make it quite certain that the beds at Sahel Alma are on a different level from those at Hakel and Hajula; while those at the latter places are on the same, or nearly the same, horizon. Opinions differ as to which are older, the fish-beds at Sahel Alma or those at Hakel, but the view of modern authorities is that those at Hakel are more ancient. This opinion appears to be supported by the character of the fishes in each. From a study of the fishes taken at Hajula, the beds containing them may belong to a slightly more recent time than that of the beds at Hakel.[5] The landscape of Lebanon has been subject to volcanic eruptions, tectonic plate movement, and the rising and dropping of sea levels. The Late Cretaceous was characterized by very high sea levels. During that time fossil-bearing limestone was formed.[6] One of the recent discoveries was made in 1989. M. Malez and A. Forsten described Hipparion from the Bekaa Valley.[7] Another find was a snake with two legs. This provided a valuable example of evolution at work, illustrating how ancient lizards became modern snakes. [8] Octopuses are some of the rarest marine fossils, since most species have no hard structures apart from a beak. An octopus's corpse cannot usually survive long enough to become fossilized, which is why the discovery of well-preserved octopuses in Lebanon in 2009 was remarkable. Dirk Fuchs of the Freie University Berlin said about these 95-million-year-old fossil octopuses found in Lebanon: This provides important evolutionary information . The more primitive relatives of octopuses had fleshy fins along their bodies . The http://en.wikipedia.org/wiki/Paleontological_sites_of_Lebanon 25.10.2012 09:18:26 Paleontological sites of Lebanon - Wikipedia, the free encyclopedia Page 2 This provides important evolutionary information. The more primitive relatives of octopuses had fleshy fins along their bodies. The “ new fossils are so well preserved that they show, like living octopus, that they didn't have these structures.[9] ” The scientific name of the new find is Keuppia levante . Some of them have been preserved so well that their ink is still visible.[9] Fossils found in Lebanon Enantiophoenix Palaeoctopus Keuppia Styletoctopus Eupodophis Palibacus Ichthyotringa See also Byblos Fossil Museum Dany Azar on Wikispecies References 1. ^ a b Fabio M.

  • Tectonic Evolution of Syria Interpreted from Integrated
    TECTONIC EVOLUTION OF SYRIA INTERPRETED FROM INTEGRATED GEOPHYSICAL AND GEOLOGICAL ANALYSIS A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Graham Edward Brew January 2001 ã Graham Edward Brew 2001 TECTONIC EVOLUTION OF SYRIA INTERPRETED FROM INTEGRATED GEOPHYSICAL AND GEOLOGICAL ANALYSIS Graham E. Brew, Ph.D. Cornell University 2001 Using a variety of geophysical and geological data, the Phanerozoic tectonic evolution of Syria has been interpreted. The study is inspired by the diverse styles of tectonic deformation within Syria generated by long-lived proximity to active plate boundaries. The work is also relevant to hydrocarbon exploration. The availablity of seismic reflection and refraction profiles, wells, and other resources made this research possible. Three studies focused on specific areas of Syria are presented. The first is a seismic refraction interpretation along a north – south profile in eastern Syria. The results show that metamorphic basement depth (and hence Paleozoic thickness) in southeast Syria is greater, by >2 km, than that in the northeast. The next study interprets the structure and tectonics in northeast Syria. During Late Paleozoic and Mesozoic time northeast Syria was an extension of the Palmyride trough. In the Maastrichtian, regional extension opened the Abd el Aziz and Sinjar graben that were structurally inverted in the Late Cenozoic to form the present topography. The third study concerns the Ghab Basin in western Syria. This 3.4 km deep Plio- Quaternary pull-apart basin suggests that the Dead Sea Fault System has only been active in Syria since the end of the Miocene in accordance with a two-phase model of Red Sea opening.

  • 2-D Basin Modeling Study of Petroleum Systems in the Levantine Basin, Eastern Mediterranean
    GeoArabia, 2011, v. 16, no. 2, p. 17-42 Gulf PetroLink, Bahrain 2-D Basin modeling study of petroleum systems in the Levantine Basin, Eastern Mediterranean Lisa Marlow, Kristijan Kornpihl and Christopher G. St. C. Kendall ABSTRACT The Levantine Basin has proven hydrocarbons, yet it is still a frontier basin. There have been significant oil and gas discoveries offshore the Nile Delta, e.g. several Pliocene gas plays and the Mango Well with ca. 10,000 bbls/day in Lower Cretaceous rocks and recently, Noble Energy discovered two gas “giants” (> 5 TCF and one estimated at 16 TFC) one of which is in a pre-Messinian strata in ca. 1,700 m (5,577 ft) water depth. Regional two-dimensional (2-D) petroleum system modeling suggests that source rocks generated hydrocarbons throughout the basin. This paper provides insight into the petroleum systems of the Levantine Basin using well and 2-D seismic data interpretations and PetroMod2D. Tectonics followed the general progression of the opening and closing of the Neo-Tethys Ocean: rift-extension, passive margin, and compression. The stratal package is up to 15 km thick and consists of mixed siliciclastic-carbonate-evaporite facies. Five potential source rock intervals (Triassic – Paleocene) are suggested. Kerogen in the older source rocks is fully transformed, whereas the younger source rocks are less mature. There are several potential reservoir and seal rocks. The model suggests that oil and gas accumulations exist in both structural and stratigraphic traps throughout the basin. INTRODUCTION Although the Levantine Basin has proven hydrocarbons, further examination of the tectono- stratigraphic and thermal history of the basin and their affect on the petroleum systems is required to lower exploration risk.

  • A Diphyletic Taxon?
    Berliner paläobiologische Abhandlungen 10 181-192 Berlin 2009-11-11 Octobrachia - a diphyletic taxon? Dirk Fuchs Abstract: Until today, the phylogenetic origin of the Octopoda and the Cirroctopoda is poorly understood, since a gladius that unambiguously links the fin supports of the both groups is still unknown from the fossil record. The present article summarises previous ideas concerning the phylogenetic and morphogenetic origin of the Octobrachia. Besides a general introduction into the gladius morphology of some coleoid families, the author focuses on two families whose gladii are well known, but which have never been considered before as potential ancestors of the Octobrachia: the Muensterellidae and the Palaeololiginidae. The author finally proposes three different phylogenetic scenarios for the derivation of the Octopoda and Ciroctopoda: A) a monophyletic origin from muensterellids, B) a monophyletic origin from palaeololiginids and C) a diphyletic origin from muensterellids and palaeololiginids. Zusammenfassung: Bis heute ist der phylogenetische Ursprung der Octopoda und Cirroctopoda ungeklärt, da der Fossilbericht noch keinen Gladiustypen hervorgebracht hat, der die Gladiusrudimente dieser beiden Gruppen eindeutig verbinden könnte. Der vorliegende Artikel fasst die früheren Vorstellungen über den phylogenetischen und morphogenetischen Ursprung der Octobrachia zusammen. Neben einer allgemeinen Vorstellung von Gladien verschiedener Coleoidenfamilien stellt der Autor zwei Familien genauer vor, deren Gladien zwar gut bekannt sind, aber noch nie als mögliche Vorläufer der Octobrachia in Betracht gezogen wurden: die Muensterellidae und die Palaeololiginidae. Abschliessend stellt der Autor drei verschiedene phylogenetische Szenarien für der Ableitungen der Octopoda und Cirroctopoda vor: A) einen mono- phyletischen Ursprung von Muensterelliden, B) einen monophyletischen Ursprung von Palaeololiginiden und C) einen diphyletischen Ursprung von Muensterelliden und Palaeololiginiden.

  • First Discovery of the Soft‐Body Imprint of an Oligocene Fossil Squid Indicates Its Piscivorous Diet
    First discovery of the soft‐body imprint of an Oligocene fossil squid indicates its piscivorous diet ALEKSANDR A. MIRONENKO , MAXIM S. BOIKO, ALEXANDRE F. BANNIKOV, ALEXANDER I.

A., & Košťák, M. 2021: First discovery of the soft‐body imprint of an Oligocene fossil squid indicates its piscivorous diet. Lethaia, https://doi.org/10.1111/let.12440. The first well‐preserved soft‐body imprint of a fossil squid was discovered from the Lower Oligocene of the Krasnodar region, Russia. The squid is perfectly preserved, with many details of its body available for study, such as imprints of eyes and head, a pair of statoliths, jaws, and stomach contents. Statoliths of this squid are the first finds of in situ statoliths in fossil non‐belemnoid coleoids, and their shape is characteristic of the genus Loligo (family Loliginidae). Although some Mesozoic coleoids were previ- ously classified as teuthids, these finds remain controversial and the squid described herein is the first unquestionable representative of fossil Teuthida known to date. It should be noted that the squid is preserved not due to phosphatization, which is typical for fossil coleoids, but by pyritization and carbonization. Numerous fish remains in the stomach contents of the squid indicate its piscivorous diet. A small cutlassfish Anenche- lum angustum, which was buried together with the squid and whose bones are located near the squid's jaws, sheds light on the circumstances of the death of this animal. Most likely, the squid suffocated in the anoxic bottom waters, where it drowned along with its last prey (distraction sinking).

  • A Phylogeny of Fossil and Living Neocoleoid Cephalopods
    A PHYLOGENY OF FOSSIL AND LIVING NEOCOLEOID CEPHALOPODS Mark Sutton1, Catalina Perales-Raya2 and Isabel Gilbert3 1 Department of Earth Science & Engineering, Imperial College, London SW7 2AZ, UK. 2 Instituto Español de Oceanografía (Centro Oceanográfico de Canarias). Vía Espaldón, Dársena Pesquera PCL 8, 38180, Santa Cruz de Tenerife, Spain 3 36 Twisden Road, London, NW5 1DN, UK. 1 Abstract Coleoid cephalopod phylogeny is well studied via both molecular and morphological data, yet while some agreement has been reached (e.g. that extant Decapodiformes and Octopoda are monophyletic) many details remain poorly resolved. Fossil coleoids, for which much data exists, have hitherto not been incorporated into analyses. Their inclusion is highly desirable both for the support of neontological phylogenies, to better reconstruct character-state histories, and to investigate the placement of the fossil groups themselves. In this study we present and analyse a morphological data matrix including both extinct and extant taxa. Homology assumptions in our data are discussed. Our results are presented both with and without the constraint of a monophyletic Decapodiformes imposed. When analysed with this constraint our results are strikingly congruent with those from molecular phylogeny, for instance placing Idiosepius in a basal position within Decapodiformes, and recovering Oegopsida and Bathyteuthoidea (though as grades). Our results support an Octopodiformes clade (‘vampire squid’ Vampyroteuthis as sister to Octopoda) and an octopodiform interpretation
