Aspidopleura
''Aspidopleura'' is an extinct monotypic genus of parasitic wasp in the Eupelmidae subfamily Neanastatinae and at present, it contains the single species ''Aspidopleura baltica''. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe. History and classification ''Aspidopleura'' is known from only two fossils, the holotype and the paratype. The holotype, number "AMNH-JWJ-409", is a single female specimen preserved in a nearly flattened amber block in size. The paratype, number "AMNH-JWJ-410", is also a single female specimen and preserved in a nearly triangular amber block in size. Both amber blocks are currently residing in the American Museum of Natural History paleoentomology collections in New York City, USA. The specimens of ''Aspidopleura baltica'' were first studied by Gary A.P. Gibson, with his 2009 Type (biology), type description being published in the journal ''ZooKeys''. The genus, generic name wash coined by Gary Gib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Amber
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. Bitterfeld amber from the brown coal mines near Bitterfeld in Germany was previously thought to be redeposited Baltic amber, but is now known to be chemically distinct, though like with Ukrainian Rovno amber, it is thought to have been deposited around the same time as Baltic amber. Because Baltic amber contains from 3 to 8% succinic acid, it is also termed succinite. Geologic context ''In situ'' Balt ...
