Studenicia is a genus of Ediacaran fauna which is approximately 635-545 million years old. All Ediacaran fauna are considered to be invertebrate Metazoans or multicellular organisms with no backbone.
Description
[edit]The fossils are made of small casts of the body. Studenicia is a small round organism (plan view) approximately 1-2 centimeters in diameter, and flat (side view). It is distinguished from other Ediacaran genera such as Nemiana by the presence of the central tubercle and Studenicia has a simpler structure (lacking rings) than Tirasiana.[1]
Diversity
[edit]Gureev only documented one species of Studenicia which is known as Studenicia galeiforma.[1]
Discovery
[edit]
Studenicia was discovered in the Studenitsa formation of the Dniester river, near Studenitsa village, Podolia, Ukraine. The fossil was discovered by Y. Gureev and first cataloged in 1983.[2][3]
Distribution
[edit]Studenicia has only been found in the Studenitsa formation of the Dniester river, near Studenitsa village, Podolia, Ukraine.
Ecology
[edit]Studenecia was a sedentary organism that lived on lower plane stratification.[1] The Studenitsa Formation outcrops are composed of grey sandstones, siltstones, and mudstones, with units of multi-grained sandstones. The outcrops have a total thickness of up to 60m in certain areas.[1]
