Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014 and 400 tonnes in 2015. Baltic amber is also found in Poland, as well as the Baltic states.
Manobiomorpha is an extinct genus of flea beetles described from the late Eocene Rovno amber of Ukraine. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Manobiomorpha eocenica.
Psyllototus is an extinct genus of flea beetles described from the late Eocene Rovno amber of Ukraine, and from the Baltic amber of Russia and Denmark. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Psyllototus progenitor. In 2016, a newly described extant flea beetle genus from Bolivia, Chanealtica, was found to be most similar to Psyllototus, based on the characters available for observation.
Paleophaedon is an extinct genus of chrysomeline leaf beetle described from the late Eocene Rovno amber of Ukraine. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Paleophaedon minutus.
Epiborkhausenites is an extinct genus of moth in the concealer moth family Oecophoridae and containing a single species Epiborkhausenites obscurotrimaculatus. The species is known only from Middle Eocene, Bartonian stage, Baltic amber deposits near the town of Palanga in Lithuania.
Yantaromyrmex is an extinct genus of ants first described in 2013. Members of this genus are in the subfamily Dolichoderinae of the family Formicidae, known from Middle Eocene to Early Oligocene fossils found in Europe. The genus currently contains five described species, Y. constrictus, Y. geinitzi, Y. intermedius, Y. mayrianum and Y. samlandicus. The first specimens were collected in 1868 and studied by Austrian entomologist Gustav Mayr, who originally placed the fossils in other ant genera until the fossils were reviewed and subsequently placed into their own genus. These ants are small, measuring from 4 to 6 mm in length and can be characterized by their trapezoidal shaped head-capsules and oval compound eyes that are located slightly to the rear of the capsules midpoint, with no known ocelli present.
Bradoponera is an extinct genus of ant in the Formicidae subfamily Proceratiinae, and is one of four genera of the subfamily. The genus contains four described species Bradoponera electrina, Bradoponera meieri, Bradoponera similis, and Bradoponera wunderlichi. The species are known from several Middle Eocene amber fossils which were found in Europe.
Embolemidae is a family of small solitary parasitoid wasps with around 70 species in 2 genera distributed around the world. The few species whose biology is known are parasites on planthopper nymphs of the families Achilidae and Cixiidae. There is debate regarding the status of the genus named Ampulicomorpha by Ashmead in 1893, generally considered now to be a junior synonym of Embolemus (e.g.,), though some authorities dispute this (e.g.,)
Pachycondyla succinea is an extinct species of ant in the formicid subfamily Ponerinae described from fossils found in Europe. P. petrosa is one of three middle Eocene Pachycondyla species found in Baltic amber.
Rovno amber, occasionally called Ukrainian amber, is amber found in the Rivne Oblast and surrounding regions of Ukraine and Belarus. The amber is dated between Late Eocene and Early Oligocene, and suggested to be contemporaneous to Baltic amber. Major exploration and mining of the amber did not start until the 1990s.
Alicodoxa is an genus of extinct planthoppers in the family Dictyopharidae. It contains a single described species, Alicodoxa rasnitsyni, known from several Late Eocene fossils found in Europe.
Nylanderia pygmaea is an extinct species of formicid in the ant subfamily Formicinae known from fossils found in the Prussian Formation of the Baltic region.
Winnertziinae is a subfamily of gall midges and wood midges in the family Cecidomyiidae.
Proneuronema is an extinct genus of lacewings in the neuropteran family Hemerobiidae known from fossils found in amber. The genus currently contains three species, P. gradatum and P. minor from Baltic amber and P. sidorchukae from Rovno amber. A Ypresian fossil from Washington state was initially also placed within the genus, having been moved from its original placement as Cretomerobius wehri, but was subsequently moved to the separate genus Archibaldia by Vladimir Makarkin (2023).

Chaenothecopsis polissica is a species of fossilized pin lichen in the family Mycocaliciaceae that was discovered in 2021 by Vasyl Heluta and Maryna Sukhomlyn. The holotype was recovered from Rovno amber, which formed in Ukraine during the late Eocene.
The Prussian Formation, previously known as the Amber Formation, is a geologic formation in Prussia, today mostly Kaliningrad Oblast that dates to the Eocene. It holds 90% of the world's amber supply and Baltic amber is found exclusively in the Prussian Formation.
