Selenocara
''Selenocara'' is an extinct genus of mastodonsauroid temnospondyl. The type species is ''Selenocara groenlandica'', described by Gunnar Säve-Söderbergh in 1935 on the basis of skull bones from the Lower Triassic Wordie Creek Formation of Greenland. Säve-Söderbergh originally described it as a new species of ''Wetlugasaurus''. The original material was redescribed in 1997 by Hans C. Bjerring, who transferred ''Wetlugasaurus groenlandicus'' to the separate genus named ''Selenocara''. Bjerring listed the quadrate condyles which were about level with the occipital condyles (both transversally and horizontally), the orbitofacial openings wholly visible through the orbitopalatine openings when viewed ventrally, and the long axes of each orbitofacial opening directed toward the ipsilateral auditive incisure as the characters justifying the exclusion of ''S. groenlandica'' from the genus ''Wetlugasaurus''. Bjerring stated that the generic name is derived from the Greek words ''se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the in ...

Triassic Temnospondyls Of Europe
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archosaurs ...

Capitosaurs
Capitosauria is an extinct group of large temnospondyl amphibians with simplified stereospondyl vertebrae. Mainly living as piscivores in lakes and rivers, the Capitosauria and its sister taxon Trematosauria were the only major labyrinthodonts that existed during the Mesozoic in ecological niches broadly similar to those of modern crocodiles, and some grew to very large sizes. At 6 meters in length, the Mid-Triassic '' Mastodonsaurus giganteus'' is not only thought to have been the largest capitosaur, but possibly also the largest amphibian to have lived. The latest known remains are from the Rhaetian of Germany and are referred to ''Cyclotosaurus''. Capitosauria was first named by Schoch and Milner (2000) and further described by Yates and Warren (2000), who assigned ''Lydekkerina'' and Mastodonsauroidea to it. It was described by Damiani (2001) under the name Mastodonsauroidea. In their phylogenetic analysis of temnospondyls, Ruta ''et al.'' (2007) placed ''Lydekkerina'' and it ...

Eigil Nielsen (paleontologist)
Eigil Hans Aage Nielsen (16 August 1910 – 8 December 1968) was a Danish paleontologist, who specialized in fossil vertebrate anatomy, particularly of Triassic bony fish. Life Eigil Nielsen was born in Copenhagen on 16 August 1910, to engineer Hans Peder Nielsen and his wife Ellen Nielsen (née Pedersen). He attended Sorø Akademi gymnasium. Already at young age, he collected fossils from different paleontological sites in Denmark. He later studied in Copenhagen, and received his Master's degree in 1935 and his doctorate degree in 1942. He studied especially fossil vertebrate faunas from Greenland, which were collected during multiple expeditions. In 1957, he became professor of paleontology in Copenhagen and curator at the Geological Museum in Copenhagen. He had been a member of the Royal Danish Academy of Sciences and Letters since 1965. He died in Gentofte on 8 December 1968 after a long illness. Research Nielsen is mostly known for his in-depth monographs on Triassic ray-fi ...

Occipital Bone
The occipital bone () is a neurocranium, cranial dermal bone and the main bone of the occiput (back and lower part of the skull). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum. At the base of skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord. Like the other cranial bones, it is classed as a flat bone. Due to its many attachments and features, the occipital bone is described in terms of separate parts. From its front to the back is the basilar part of occipital bone, basilar part, also called the basioccipital, at the sides of the foramen magnum are the lateral parts of occipital bone, lateral parts, also called the exoccipitals, and the back is named as the squamous part of occipital bone, squamous part. The basilar part is a thick, somewhat quadrilateral piece in front of the foramen magnum and directed towards the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
