Rovno amber

[3] The two formations total between 2–7 m (6.6–23.0 ft) in thickness, both containing interbeds or mixtures of brown coals and carbonized vegetation.

[6] Small amounts of rough, partially worked, and fully shaped amber have been recovered from Paleolithic and Neolithic sites in the Dnieper area.

Dating of the site ranges between 13,300 and 10,500 B.C., when the regions of Baltic amber deposits in Kaliningrad and Lithuania were still covered with ice-sheets.

[3] As such, before the 1990s amber recovery wasn't overseen by the Ukrainian government, with small amounts found after rains and thaws and during well construction and while the Kyiv-Kovel rail line was being built.

[2] Small scale collecting of the amber started to gain momentum in the 1950s when granite deposits in the Klesiv area were beginning to be developed.

[3] Following an increase in the amber for jewelry production in Kyiv, Lithuania, and Poland, during the 1970s investigation and eventual start of the Pugach quarry in Klesiv culminated in 1991.

[8] The majority of Rivne amber is mined from the lower part of the aforementioned Formation, with the most notable locality being the Pugach Quarry in Klesiv.

[10] There are a number of arthropod taxa, ranging from planthoppers, such as Alicodoxa, and ants to mites and spiders that are shared between Rivne and Baltic amber.

[2] There are several hundred families of arthropods identified from Rovno amber, with major reviews being compiled by Perkovsky et al (2003, 2007, 2010).
