Sacisaurus
''Sacisaurus'' (" Saci lizard") is a silesaurid dinosauriform from the Late Triassic ( Norian) Caturrita Formation of southern Brazil. The scientific name, ''Sacisaurus agudoensis'', refers to the city where the species was found, Agudo in the Rio Grande do Sul state, whereas ''Sacisaurus'' refers to Saci, a famous one-legged creature from Brazilian mythology, because among the dozens of fossil material unearthed, 35 right femora were collected whereas only 1 left femur was found. Characteristics ''Sacisaurus'' was approximately long and high, based on the largest femoral specimen. Some elements that were originally mentioned in the description study were reassigned to other taxa afterwards. Its long and strong legs indicate that it was a fast animal. The biggest teeth of the genus were just long. The well-preserved jaw indicates that ''Sacisaurus'' was an herbivore, and there is a process at the tip that resembles the ornithischian predentary bone. Further research ...

Diodorus (genus)
''Diodorus'' is a genus of silesaurid dinosauriforms (relatives of dinosaurs) from the Late Triassic (Carnian - Norian) Timezgadiouine Formation of the Argana Basin of Morocco. Discovery The first fossils of this taxon were discovered by a team from Harvard University in the northeastern Argana Basin, east of Imziln, Morocco, with support from the National Geographic Society and permission from the Moroccan Ministry of Energy and Mines. The remains were found in a quarry at of the Irohalene Mudstone Member of the Timezgadiouine Formation, as part of a layer of disarticulated specimens that included fossils of phytosaurs, prolacertiforms, fish, and temnospondyls. In 2012, the paleontologists Christian F. Kammerer, Sterling J. Nesbitt, and Neil H. Shubin scientifically described the remains, and identified them as representing the first body fossil record of the group Silesauridae from northern Africa. Based on these fossils, they named the new genus and species ''Diodorus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caturrita Formation
The Caturrita Formation is a geological formation, rock formation found in Rio Grande do Sul, Brazil. Its sediments were deposited in the Paraná Basin. The formation is from the Upper Triassic and forms part of the Santa Maria Supersequence in the upper section of the Rosário do Sul Group. Etymology The formation received this name, because Caturrita is a neighbourhood (barrio) of Santa Maria, Rio Grande do Sul, Santa Maria. In Portuguese ''caturrita'' also refers to the monk parakeet. Stratigraphy The sediments of the Caturrita Formation belong to the second unit of the Santa Maria Supersequence and overlie the Alemoa Member of the Santa Maria Formation. The clayey sediments of the Alemoa Member gradually give way to the more sandy, rarely conglomeratic, Caturrita Formation, which finishes with an unconformity. After this erosional event follow the Rhaetian sediments of the Mata Sandstone, the third unit of the Santa Maria Supersequence. The Caturrita Formation was once re ...

Silesauridae
Silesauridae is an extinct family of Triassic dinosauriforms. It is most commonly considered to be a clade of non-dinosaur dinosauriforms, and the sister group of dinosaurs. Some studies have instead suggested that most or all silesaurids comprised an early diverging clade or a paraphyletic grade within ornithischian dinosaurs. Silesaurids have a consistent general body plan, with a fairly long neck and legs and possibly quadrupedal habits, but most silesaurids are heavily fragmentary nonetheless. Furthermore, they occupied a variety of ecological niches, with early silesaurids (such as '' Lewisuchus'') being carnivorous and later taxa (such as ''Kwanasaurus'') having adaptations for specialized herbivory. As indicated by the contents of referred coprolites, '' Silesaurus'' may have been insectivorous, feeding selectively on small beetles and other arthropods. Classification Silesauridae is typically considered the sister group to Dinosauria. The group was named in 2010 by Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saci (Brazilian Folklore)
Saci ( ) is a character in Brazilian folklore. He is a one-legged black man, who smokes a pipe and wears a magical red cap that enables him to disappear and reappear wherever he wishes (usually in the middle of a Dirt devil). Considered an annoying prankster in most parts of Brazil, and a potentially dangerous and malicious creature in others, he nevertheless grants wishes to anyone who manages to trap him or steal his magic cap. However, his cap is often depicted as having a bad smell. Most people who claimed to have stolen this cap say they can never wash the smell away. The legend says that a person can trap a Saci inside a bottle when he is in the form of a dust devil. There are several variants of the myth, including: Saci-pererê (), black as coal; Saci-trique (), bi-racial and more benign; Saci-saçurá (), with red eyes. Powers, weaknesses, and habits An incorrigible prankster, the Saci causes no major harm, but there is no little harm that he won't do. He hides childre ...

Dinosauriformes
Dinosauromorpha is a clade of avemetatarsalian archosaurs (reptiles closer to birds than to crocodilians) that includes the Dinosauria (dinosaurs) and some of their close relatives. It was originally defined to include dinosauriforms and lagerpetids, with later formulations specifically excluding pterosaurs from the group. Birds are the only dinosauromorphs which survive to the present day. Classification The name "Dinosauromorpha" was briefly coined by Michael J. Benton in 1985. It was considered an alternative name for the group "Ornithosuchia", which was named by Jacques Gauthier to correspond to archosaurs closer to dinosaurs than to crocodilians. Although "Ornithosuchia" was later recognized as a misnomer (since ornithosuchids are now considered closer to crocodilians than to dinosaurs), it was still a more popular term than Dinosauromorpha in the 1980s. The group encompassed by Gauthier's "Ornithosuchia" and Benton's "Dinosauromorpha" is now given the name Avemetatar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agudo, Rio Grande Do Sul
Agudo is a municipality in Rio Grande do Sul, the southernmost state of Brazil. Location Agudo is 83 meters above sea level. The total area is 553,1 km² and the population was estimated at 16,401 in 2020. The municipality contains part of the Quarta Colônia State Park, created in 2005. The municipality contains part of the hydroelectric Dona Francisca Dam on the upper Jacuí River. History Archeological evidence indicates that this area was settled by humankind as far back as 8,000 years ago. The first Europeans to come into the area were Jesuit priests who in the 16th century began establishing the so-called ''Reductions'' or '' Missions'' as they also were named in the wider region (i.e. Brazil, Argentina and Paraguay). At a later date with the expulsion of the Jesuit order by both the Spanish and Portuguese crowns from South America left the area inactive as far as European activities were concerned. The local indigenous population suffered attacks by Paulistas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predentary
Ornithischia () is an extinct order of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. The name ''Ornithischia'', or "bird-hipped", reflects this similarity and is derived from the Greek stem ' (), meaning "of a bird", and ' (), plural ', meaning "hip joint". However, birds are only distantly related to this group as birds are theropod dinosaurs. Ornithischians with well known anatomical adaptations include the ceratopsians or "horn-faced" dinosaurs (e.g. ''Triceratops''), the pachycephalosaurs or "thick-headed" dinosaurs, the armored dinosaurs (Thyreophora) such as stegosaurs and ankylosaurs, and the ornithopods. There is strong evidence that certain groups of ornithischians lived in herds, often segregated by age group, with juveniles forming their own flocks separate from adults. Some were at least partially covered in filamentous (hair- or feather- like) pelts, and there is much debate over whether these filaments fou ...

Fossils Of Brazil
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''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolut ...

Triassic Brazil
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 archosaur ...
