Lucianovenator Scale
''Lucianovenator'' is an extinct genus of coelophysidae, coelophysid Theropoda, theropod dinosaur which lived in Argentina during the Triassic. The genus name ''Lucianovenator'' translates to "Luciano's hunter", in reference to Don Luciano Leyes, who first reported the remains. The species name ''bonoi'' refers to Tulio del Bono, a local scientific authority who collaborated on the describers' research. It is one of the few Neotheropoda, neotheropods known from South America. Discovery The holotype (PVSJ 906) of ''Lucianovenator bonoi'' was found in the "Quebrada del puma" locality of the Quebrada del Barro Formation in Argentina, which is estimated to be from the late Norian to Rhaetian in age, approximately 210 to 202 million years ago. PVSJ 906 represents an articulated vertebral sequence from the third Cervical vertebrae, cervical to fourth dorsal vertebra, as well as a sacrum and a partial pelvis. In addition, three more specimens were referred to ''Lucianovenator''. These in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Pelvis
The pelvis (plural pelves or pelvises) is the lower part of the trunk, between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis, or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs (sex organs) and the rectum, while the pelvic f ...

2017 In Archosaur Paleontology
The year 2017 in archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is the scientific study of those animals, especially as they existed before the Holocene Epoch began about 11,700 years ago. The year 2017 in paleontology included various significant developments regarding archosaurs. This article records new taxa of fossil archosaurs of every kind that have been described during the year 2017, as well as other significant discoveries and events related to paleontology of archosaurs that occurred in the year 2017. General research * A study on the evolution of forelimb anatomy, musculature and joint ranges of motion from early archosaurs to sauropodomorph dinosaurs based on data from ''Mussaurus patagonicus'' and extant freshwater crocodile is published by Otero ''et al.'' (2017). Pseudosuchians Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timeline Of Coelophysoid Research
This timeline of coelophysoid research is a chronological listing of events in the History of paleontology, history of paleontology focused on the coelophysoids, a group of primitive theropod dinosaurs that were among Earth's dominant predators during the Late Triassic and Early Jurassic epochs. Although formally trained scientists didn't discover coelophysoid fossils until the late : 19th century in paleontology, 19th century, Native Americans in the United States, Native Americans of the modern southwestern United States may have already encountered their fossils. Navajo people, Navajo creation mythology describes the early Earth as being inhabited by a variety of different kinds of monsters who hunted humans for food. These monsters were killed by storms and the heroic Monster Slayers, leaving behind their bones. As these tales were told in New Mexico not far from bonebeds of ''Coelophysis'', this dinosaur's remains may have been among the fossil remains that inspired the story. ...

Taphonomic Bias
Taphonomy is the study of how organisms decay and become fossilized or preserved in the paleontological record. The term ''taphonomy'' (from Greek , 'burial' and , 'law') was introduced to paleontology in 1940 by Soviet scientist Ivan Efremov to describe the study of the transition of remains, parts, or products of organisms from the biosphere to the lithosphere. The term taphomorph is used to describe fossil structures that represent poorly-preserved, deteriorated remains of a mixture of taxonomic groups, rather than of a single one. Description Taphonomic phenomena are grouped into two phases: biostratinomy, events that occur between death of the organism and the burial; and diagenesis, events that occur after the burial. Since Efremov's definition, taphonomy has expanded to include the fossilization of organic and inorganic materials through both cultural and environmental influences. This is a multidisciplinary concept and is used in slightly different contexts througho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
