Tremp Formation
The Tremp Formation (, ), alternatively described as Tremp Group (), is a geological Formation (geology), formation in the comarca Pallars Jussà, Lleida Province, Lleida, Spain. The formation is restricted to the Tremp-Graus Basin, Tremp or Tremp-Graus Basin (), a piggyback basin, piggyback foreland basin in the Catalonian Pre-Pyrenees. The formation dates to the Maastrichtian to Thanetian,Pujalte & Schmitz, 2005, p.82 thus the formation includes the Cretaceous-Paleogene boundary that has been well studied in the area, using paleomagnetism and carbon and oxygen isotopes. The formation comprises several lithologies, from sandstone, conglomerate (geology), conglomerates and shales to marls, siltstones, limestones and lignite and gypsum beds and ranges between in thickness. The Tremp Formation was deposited in a continental to marginally marine fluvial-lacustrine environment characterized by estuary, estuarine to river delta, deltaic settings. The Tremp Basin evolved into a sedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphagesauridae
Sphagesauridae is a Gondwanan family of mesoeucrocodylians that lived during the Late Cretaceous. It was a clade of terrestrial crocodilians that evolved very mammal-like teeth and jaws.MARINHO, T.S. & CARVALHO, I.S. Revision of the Sphagesauridae KUHN, 1968 (Crocodyliformes, Mesoeucrocodylia).

Caipirasuchus
''Caipirasuchus'' is an extinct genus of sphagesaurid notosuchians known from the Late Cretaceous of northern São Paulo State and western Minas Gerais State, southeastern Brazil. The type species, ''C. paulistanus'', was named in 2011. A second species, ''C. montealtensis'', was referred to ''Caipirasuchus'' in 2013 after having been named in 2008 as a species of '' Sphagesaurus''. A third species, ''C. stenognathus'', was described in 2014. A fourth species, ''C. mineirus'', was described in 2018. A fifth species, ''C. attenboroughi'', was named in 2021 in honour of David Attenborough, and a sixth species, ''C. catanduvensis'', was described in 2024, with a distinct chamber associated with the airways, possibly used in vocalization. Discovery and naming ''Caipirasuchus'' was first named by Fabiano V. Iori and Ismar S. Carvalho in 2011 and the type species is ''C. paulistanus''. The generic name is derived from Tupi word ''Caipira'' which refers to the traditional inhabit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skull Of Aplestosuchus Sordidus
The skull, or cranium, is typically a Bone, bony enclosure around the brain of a vertebrate. In some fish, and amphibians, the skull is of cartilage. The skull is at the head end of the vertebrate. In the human, the skull comprises two prominent parts: the neurocranium and the facial skeleton, which evolution, evolved from the first pharyngeal arch. The skull forms the frontmost portion of the axial skeleton and is a product of cephalization and brain vesicle, vesicular enlargement of the brain, with several special senses structures such as the eyes, ears, nose, tongue and, in fish, specialized touch, tactile organ (biology), organs such as barbel (zoology), barbels near the mouth. The skull is composed of three types of bone: cranial bones, facial bones and ossicles, which is made up of a number of fused flat bone, flat and irregular bones. The cranial bones are joined at firm fibrous junctions called suture (joint), sutures and contains many foramina, fossa (anatomy), fos ...

Baurusuchidae
Baurusuchidae is a Gondwanan family of mesoeucrocodylians that lived during the Late Cretaceous. It is a group of terrestrial hypercarnivorous crocodilians from South America (Argentina and Brazil) and possibly Pakistan. Baurusuchidae has been, in accordance with the PhyloCode, officially defined as the least inclusive clade containing '' Cynodontosuchus rothi, Pissarrachampsa sera,'' and '' Baurusuchus pachecoi.'' Baurusuchids have been placed in the suborder Baurusuchia, and two subfamilies have been proposed: Baurusuchinae and Pissarrachampsinae. Genera Several genera have been assigned to Baurusuchidae. ''Baurusuchus'' was the first, being the namesake of the family. Remains of ''Baurusuchus'' have been found from the Late Cretaceous Bauru Group of Brazil in deposits that are Turonian - Santonian in age. In addition to ''Baurusuchus'', five other South American crocodyliforms have been assigned to Baurusuchidae: '' Campinasuchus'', '' Cynodontosuchus'', '' Pissarrachampsa ...

Adamantina Formation
The Adamantina Formation is a geological Formation (geology), formation in the Bauru Basin of western São Paulo (state), São Paulo state in southeastern Brazil. Its strata date back to the Late Cretaceous epoch of the Cretaceous, Cretaceous Period, during the Mesozoic Era. The formation is part of the Bauru Group in the northeastern Paraná Basin. Geology Dinosaur remains are among the fossils that have been recovered from the Adamantina Formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, South America)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 600-604. . According to some studies, the Adamantina Formation dates from the Turonian to the Santonian stage (90-83.5 million years ago) of the late Cretaceous, other studies have found a much younger age - Campanian to Maastrichtian (83.5-66 million years ago) of the late Cretaceous. More recent studies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aplestosuchus
''Aplestosuchus'' is an extinct genus of baurusuchid mesoeucrocodylian known from the Late Cretaceous Adamantina Formation of São Paulo, southern Brazil. It contains a single species, ''Aplestosuchus sordidus''. ''A. sordidus'' is represented by a single articulated and nearly complete skeleton, preserving the remains of an unidentified sphagesaurid crocodyliform in its abdominal cavity. The specimen represents direct evidence of predation between different taxa of crocodyliforms in the fossil record. Discovery ''Aplestosuchus'' is known solely from the holotype LPRP/USP 0229a, an articulated and nearly complete skeleton including the skull, housed at the Laboratório de Paleontologia, Universidade de São Paulo. Additionally, isolated teeth and skull bones of an unidentified sphagesaurid crocodyliform were preserved in the abdominal cavity of LPRP/USP 0229a, and assigned to the specimen number LPRP/USP 0229b. The find represents direct evidence of predation between differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
