Repedea Hill Fossil Site

Repedea Hill Fossil Site is a nature reserve located 9 km south of Iași, in the historical region of Moldavia, Romania. Repedea Hill is part of the Iași Ridge, at the contact between the Central Moldavian Plateau and the Jijia Plain.

History

First studies of the zone were in 1862, when Grigore Cobălcescu, professor at the University of Iași, published the "Repedea's Limestone" research article. These scientific studies, describing the fossil fauna, are considered to be the birth document of the Romanian geology.
In 1953, the perimeter was declared a reserve, being the first geological reserve in Romania. The total area of 44.3 ha consists of the proper scientific area of 5.8 ha, and a buffer zone of 38.5 ha.

Geology

The fossils and the limestone discovered in the area were part of the former Paratethys (Sarmatic) Sea. The scientific area includes the limestone walls, the former quarries, the caves and an area of the structural plateau. Many Basarabian lithological outcrops are protected within the scientific reserve and contain a rich and important Sarmatian fossil deposit, representative for the Moldavian Platform. The buffer zone is largely located on the Repedea structural plateau, which represents a reversed cuesta.
