Stomatosuchus
''Stomatosuchus'' (meaning "mouth crocodile") is an extinct stomatosuchid neosuchian from the Late Cretaceous (Cenomanian) Bahariya Formation of Egypt. The type and only species is ''S. inermis''. Much of what is known about ''Stomatosuchus'' has been inferred from the related genus ''Laganosuchus''. Discovery and naming The only known specimen of ''S. inermis'' consisted of a partial skull and two caudal vertebrae. It was collected in Egypt during 1911 by the German paleontologist Ernst Stromer whilst on an expedition.Stromer, E. (1925)Ergebnisse der Forschungsreisen Prof. E. Stromers in den Wüsten Ägyptens.

Stomatosuchidae
Stomatosuchidae is an extinct family of neosuchian crocodylomorphs. It is defined as the most inclusive clade containing ''Stomatosuchus inermis'' but not '' Notosuchus terrestris'', '' Simosuchus clarki'', '' Araripesuchus gomesii'', '' Baurusuchus pachecoi'', '' Peirosaurus torminni'', or ''Crocodylus niloticus''. Two genera are known to belong to Stomatosuchidae: ''Stomatosuchus'', the type genus, and '' Laganosuchus''. Fossils have been found from Egypt, Morocco, and Niger. Both lived during the Cenomanian stage of the Late Cretaceous. The skulls of stomatosuchids are said to be platyrostral because they have unusually flattened, elongate, duck-shaped craniums with U-shaped jaws. This platyrostral condition is similar to what is seen in the "nettosuchid" '' Mourasuchus'', which is not closely related to stomatosuchids as it is a more derived alligatoroid that existed during the Miocene. Unlike ''Mourasuchus'', stomatosuchids have jaws that are less strongly bowed. Additionall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernst Stromer
Ernst Freiherr Stromer von Reichenbach (born on 12th of June, 1871 in Nürnberg, died on 18th of December, 1952 in Erlangen) was a German paleontologist best remembered for his expedition to Egypt, during which the discovery of the first known remains of ''Spinosaurus'' was made. Stromer described several discoveries made in Egypt, including a few dinosaurs from the Cretaceous period discovered in Egypt ('' Aegyptosaurus,'' ''Bahariasaurus'', and '' Carcharodontosaurus''), an enigmatic theropod (''Spinosaurus aegyptiacus'') and a giant crocodilian ('' Stomatosuchus''). In 1929 fossil bird genus ''Stromeria'' (now included in the genus ''Eremopezus'') were named in Stromer’s honour by Kálmán Lambrecht. Smith et al. (2001) also named the sauropod '' Paralititan stromeri'' in his honour. Many of the fossils discovered by Stromer were destroyed during World War II, leaving today’s scientists only a few photographs of the previously existing specimens to rely on. Biog ...

Laganosuchus
''Laganosuchus'' is an extinct genus of stomatosuchid crocodyliform. Fossils have been found from Niger and Morocco and date back to the Upper Cretaceous. Discovery The name means "pancake crocodile" from the Greek , ("pancake") and , ("crocodile") in reference to the shallow depth of the skull, which is characteristic of all stomatosuchids. It has been nicknamed "PancakeCroc" by Paul Sereno and Hans Larsson, who first described the genus in a monograph published in ''ZooKeys'' in 2009 along with other Saharan crocodyliformes such as '' Anatosuchus'' and '' Kaprosuchus''. The type species is ''L. thaumastos'' (meaning 'the astonishing pancake crocodile' from Greek θαυμαζω, ''thaumazo'' "I astonish" in reference to its unusual form) from the Cenomanian-age Echkar Formation in Niger, holotype MNN IGU13. A second species, ''L. maghrebensis'' (making a reference to the place of discovery), is known from the Kem Kem Beds in Morocco, which are also Cenomanian in age; its ho ...

Prehistoric Pseudosuchian Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Taxa Described In 1925
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Taxa Named By Ernst Stromer
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenomanian Genera
The Cenomanian is, in the International Commission on Stratigraphy's (ICS) geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...
