Unexpected palaeodiversity of omaliine rove beetles in Eocene Baltic amber (Coleoptera, Staphylinidae, Omaliinae) [PDF]
ZooKeys, 2019 Fossil records of the subfamily Omaliinae are fragmentary and most of them are less informative compression fossils. Baltic amber from the mid-Eocene of northern Europe is one of the most important sources of insect fossils, but only two reliably placed ...

A two‐photon fluorescence micro‐spectroscopy method for chemotaxonomic characterization of fossil resins [PDF]
Appl Plant SciAbstract Premise Amber, a fossilized chemical defensive exudate, is important for understanding ancient plant–insect/pathogen interactions, yet its botanical origins, especially for Cretaceous amber, remain enigmatic. Here, we develop and apply a fluorescence micro‐spectroscopy approach within the context of a larger study on the provenance of amber ...
