The Khuren Dukh Formation, also known as the Khukhtyk Formation, Khukhteeg Formation, or Hühteeg Svita, (, ), is a geological Formation (geology), formation in Mongolia whose strata date back to the Aptian–Albian ages of the Early Cretaceous.Nichols et al., 2006 Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel et al., 2004, pp.563-570 Vertebrate paleofauna Dinosaurs The earliest record of Pachycephalosauridae, Pachycephalosauria.https://vertpaleo.org/wp-content/uploads/2023/10/2023_SVP_Program-Final-10032023.pdf Choristoderes See also * List of dinosaur-bearing rock formations References Bibliography * * * * {{DEFAULTSORT:Huhteeg Svita Geologic formations of Mongolia Lower Cretaceous Series of Asia Cretaceous Mongolia Albian Stage Sandstone formations Mudstone formations Lacustrine deposits Paleontology in Mongolia Dornogovi Province, Formations ...

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 (geology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
