Uhangri Formation
The Uhangri Formation (), located at the Haenam County, Haenam, South Jeolla Province, Jeollanam-do, South Korea is a non-marine geological Formation (geology), formation known with epiclastic fluvio-lacustrine sequence with minor volcaniclastics. Ichnofossils are found in the upper part of the Uhangri Formation, and they are associated with ripple marks, indicating the part of the formation was the shallow lake margin. Fossil contents Ichnofossils Pterosaur, dinosaur, and bird tracks are preserved in situ, nearby the Haenam Uhangri Dinosaur Museum. Unnamed tracks of theropods, sauropods and ornithopods are known from the Uhangri Formation. Star-shaped dinosaur trackway with an unknown trackmaker has been discovered and described. It is unsure whether it represents manus-only trackway made by a sauropod trackmaker during swimming, or undertracks made by an ornithopod trackmaker.

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] |
