Lago Colhué Huapí Formation
The Lago Colhué Huapí Formation is a Late Cretaceous geologic formation of the Chubut Group in the Golfo San Jorge Basin in Patagonia, Argentina. The formation, named after Lake Colhué Huapí, is overlain by the Salamanca Formation of the Río Chico Group and in some areas by the Laguna Palacios Formation.Casal ''et al.'', 2015 The strata of the Lago Colhué Huapé Formation were thought to pertain to the Bajo Barreal Formation, but are now recognized as a distinct stratigraphic unit in their own right.Clyde ''et al.'', 2014 Vertebrate paleofauna Taxa recovered from the Lago Colhué Huapí Formation include the sauropods '' Aeolosaurus colhuehaupiensis'', ''Argyrosaurus'', and ''Elaltitan'', as well as the hadrosaurid ''Secernosaurus'' and the probable elasmarian ornithopod '' Sektensaurus''.Martínez ''et al.'', 2016Casal ''et al.'', 2007Mannion & Otero, 2012 The dubious possible ceratopsian ''Notoceratops'' was also present.

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Argyrosaurus
''Argyrosaurus'' ( ) is a genus of titanosaurian sauropod dinosaur that lived about 70 million years ago, during the Late Cretaceous Period of what is now Argentina. Discovery and naming The type species, ''Argyrosaurus superbus'', was formally described by Richard Lydekker in 1893. The holotype specimen of ''Argyrosaurus superbus'' is a huge left forelimb, MLP 77-V-29-1. found at Chico River, a Campanian/Maastrichtian horizon in the Lago Colhué Huapi Formation. The material includes the humerus, ulna, radius, and all five metacarpals. Recent stratigraphic information from the Lago Colhue Huapi Formation has the area that the holotype was collected from being a more probable early late Maastrichtian age instead of early Coniacian. When discovered, the forelimb was apparently a part of a complete skeleton, however, during excavation the rest of the remains were completely destroyed. In the same publication, Lydekker assigned a partial left femur from Chubut Province, MLP 21, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Journal Of Vertebrate Paleontology
The ''Journal of Vertebrate Paleontology'' is a bimonthly peer-reviewed scientific journal that was established in 1980 by Jiri Zidek (University of Oklahoma).

Megaraptora
Megaraptora is a clade of carnivorous Tetanurae, tetanuran theropod dinosaurs with controversial relations to other theropods. Its Derived (phylogenetics), derived members, the Megaraptoridae are noted for their elongated hand claws and proportionally large arms, which are usually reduced in size in other large theropods. Megaraptorans are incompletely known, and no complete megaraptoran skeleton has been found. However, they still possessed a number of unique features. Their forelimbs were large and strongly built, and the Glossary of dinosaur anatomy#ulna, ulna bone had a unique shape in members of the Family (biology), family Megaraptoridae, a subset of megaraptorans which excludes ''Fukuiraptor'' and ''Phuwiangvenator''. The first two fingers were elongated, with massive curved claws, while the third finger was small. Megaraptoran skull material is very incomplete, but a juvenile ''Megaraptor'' described in 2014 preserved a portion of the snout, which was long and slender. Le ...

Notoceratops
''Notoceratops'' (meaning "southern horned face") is a dubious genus of extinct ornithischian dinosaur based on an incomplete, toothless left dentary (now lost) from the Late Cretaceous of Patagonia (in Argentina), probably dating to the Campanian or Maastrichtian. It was most likely a ceratopsian and it was found in the Lago Colhué Huapi Formation. Discovery and naming In 1918, palaeontologist Augusto Tapia (1893–1966) discovered the genus holotype. He also named the type species, ''N. bonarellii'' (originally spelt as ''Notoceratops Bonarelli''), in 1918. The generic name is derived from Greek ''notos'', "the south", ''keras'', "horn" and ''ops'', "face". The specific name honours Guido Bonarelli (1871-1951), who advised Tapia in his study of the find. By present conventions the epithet is spelled ''bonarellii'', thus without a capital B. In many later publications the specific name is misspelled "bonarelli", with a single "i", from the incorrect assumption it would be de ...
