Peirosaurus
''Peirosaurus'' is an extinct genus of peirosaurid crocodylomorph known from the Late Cretaceous period (late Maastrichtian stage) of Minas Gerais, southern Brazil. It contains a single species, ''Peirosaurus torminni''. It is the type genus of the family Peirosauridae. Discovery ''Peirosaurus'' is known from the holotype DGM 433-R, fragmentary skull (left premaxilla bearing five teeth, isolated maxillary and dentary teeth and left palpebral bone) and partial postcranial skeleton including radius, ulna, left pubis and ischium, some presacral and a single caudal vertebrae, ribs, haemal arches and dermal plates. It was collected by Llewellyn Ivor Price in 1947-1949 at the Price Quarry 3, Peirópolis Site near Uberaba, in the Serra de Galga Member of the Marília Formation (Bauru Group), dating to the late Maastrichtian stage of the Late Cretaceous, about 68-66 million years ago. A partial skull and several postcranial elements such as vertebrae and dermal plates from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peirosaurid
Peirosauridae is a Gondwanan family of mesoeucrocodylians that lived during the Cretaceous period. It was a clade of terrestrial crocodyliforms that evolved a rather dog-like form, and were terrestrial carnivores. It was phylogenetically defined in 2004 as the most recent common ancestor of ''Peirosaurus'' and Lomasuchinae and all of its descendants. Lomasuchinae is a subfamily of peirosaurids that includes the genus ''Lomasuchus''. Lomasuchinae was defined in the same 2004 study as the most recent common ancestor of ''Lomasuchus'' and Mahajangasuchini and all of its descendants. Mahajangasuchini, also constructed in the study, was defined as the most recent common ancestor of ''Mahajangasuchus'' and ''Uberabasuchus'' and all of its descendants. However, all more recent phylogenetic analyses placed ''Mahajangasuchus'' within its own family, Mahajangasuchidae, along with the newly named ''Kaprosuchus''.

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger 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, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palpebral (bone)
The palpebral bone is a small dermal bone found in the region of the eye socket in a variety of animals, including crocodilians and ornithischian dinosaurs. It is also known as the adlacrimal or supraorbital, although the latter term may not be confused with the supraorbital in osteichthyan fishes. In ornithischians, the palpebral can form a prong that projects from the front upper corner of the orbit. It is large in heterodontosaurids, basal ornithopods such as ''Thescelosaurus'' (as ''Bugenasaura'') and ''Dryosaurus'', and basal ceratopsians such as '' Archaeoceratops'';You Hailu and Dodson, Peter. (2004). Basal Ceratopsia. In: Weishampel, David B.; Dodson, Peter; and Osmolska, Halszka (eds.) ''The Dinosauria'' (2nd Edition). Berkeley: University of California Press. p. 478–493. in these animals, the prong is elongate and would have stuck out and over the eye like a bony eyebrow. As paleoartist Gregory S. Paul has noted, elongate palpebrals would have given their owners fierc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebrae
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the vertebral column, backbone), and on the other with phylogenetic differences among the vertebrate taxon, taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Million Years Ago
The abbreviation Myr, "million years", is a unit of a quantity of (i.e. ) years, or 31.556926 teraseconds. Usage Myr (million years) is in common use in fields such as Earth science and cosmology. Myr is also used with Mya (million years ago). Together they make a reference system, one to a quantity, the other to a particular place in a year numbering system that is ''time before the present''. Myr is deprecated in geology, but in astronomy ''Myr'' is standard. Where "myr" ''is'' seen in geology it is usually "Myr" (a unit of mega-years). In astronomy it is usually "Myr" (Million years). Debate In geology a debate remains open concerning the use of ''Myr'' (duration) plus ''Ma'' (million years ago) versus using only the term ''Ma''. In either case the term '' Ma'' is used in geology literature conforming to ISO 31-1 (now ISO 80000-3) and NIST 811 recommended practices. Traditional style geology literature is written The "ago" is implied, so that any such year number "X Ma" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bauru Group
The Bauru Group is a geological group of the Bauru Sub-basin, Paraná Basin in Minas Gerais, São Paulo, General Salgado, Itapecuru-Mirim, Mato Grosso, Brazil whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. Subdivisions According to a 2016 study: The Bauru Basin covers an area of approximately 379.362 km2 located almost exclusively in Brazil.., with selected outcrops in Northeastern Paraguay (Fúlfaro, 1996). This Cretaceous sedimentary succession reflects changing nonmarine environments, such as eolian, lacustrine, fluvial and alluvial fans. The Bauru Group was divided by Fernandes and Coimbra (1996) in four formations, namely Adamantina, Uberaba, Araçatuba and Marília. In 1998, Fernandes revised the group and recognize six formations, Uberaba, Vale do Rio do Peixe, Araçatuba, São José do Rio Preto, Presidente Prudente and Marília. The Adamantina Formation was divided in Vale do Rio do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uberaba
Uberaba () is a city in the state of Minas Gerais, southeast Brazil. It is located in the Brazilian Highlands at above sea level on the Uberaba River, and away from the state capital, Belo Horizonte. The city status was granted in 1856, and its name comes from the Tupi language meaning "bright water". As of 2021 the population was 340,277 inhabitants. History The history of Uberaba begins in 1810 when capt. Major Eustaquio founded a settlement in the vicinity of the ancient route of Anhanguera (also known as the 'Goyazes road') to serve as a stopping point for locals and travelers during the 19th century. Given the strategic location of the village and as a crossroads, local farmers started to cultivate crops and domesticate cattle for commerce which led the establishment of a strong livestock network for that region. The territory of Uberaba was part of the Captaincy of Goias until 1816, being annexed to the Captaincy of Minas Gerais in the same year. It was raised to pari ...

Ischium
The ischium () forms the lower and back region of the (''os coxae''). Situated below the ilium and behind the pubis, it is one of three regions whose fusion creates the . The superior portion of this region forms approximately one-third of the acetabulum. |
Pubis (bone)
In vertebrates, the pubic region ( la, pubis) is the most forward-facing (ventral and anterior) of the three main regions making up the coxal bone. The left and right pubic regions are each made up of three sections, a superior ramus, inferior ramus, and a body. Structure The pubic region is made up of a ''body'', ''superior ramus'', and ''inferior ramus'' (). The left and right coxal bones join at the pubic symphysis. It is covered by a layer of fat, which is covered by the mons pubis. The pubis is the lower limit of the suprapubic region. In the female, the pubic region is anterior to the urethral sponge. Body The body forms the wide, strong, middle and flat part of the pubic region. The bodies of the left and right pubic regions join at the pubic symphysis. The rough upper edge is the pubic crest, ending laterally in the pubic tubercle. This tubercle, found roughly 3 cm from the pubic symphysis, is a distinctive feature on the lower part of the abdominal wall; important ...
