The review presents methods that are used frequently for multi-analytical study of fossil
resins. The preliminary characterization relies on physical methods such as microhardness …

Fossil resins are the one of several fossil tree products, together with leaves, wood, seeds,
or pollen. As an emanation of organic matter, resins are made of organic compounds …

Amber exquisitely preserves the delicate organs of fossil flowers for millions of years.
However, flower inclusions can be rare and usually do not exceed 10 mm in size. Here we …

Abstract Extant cicada (Hemiptera: Cicadoidea) includes widely distributed Cicadidae and
relictual Tettigarctidae, with fossils ascribed to these two groups based on several distinct …

For social insects such as ants, the internal organs are likely important in understanding
their eusocial behavior and evolution. Such organs, however, are rarely preserved on …

A non-biting midge of the cosmopolitan family Chironomidae (Podonominae) is recorded in
amber from the Anglesea Coal Measures, southeastern Australia. The new morphotype is …

As the only direct records of the history of evolution, it is critical to determine the geological
source of biota-bearing fossils. Through the application of synchrotron-radiation micro …

Amber first became relatively abundant and widespread in the geological record during the
Cretaceous period. It originated often as copious resin production by a variety of …

Premise Molecular studies based on chloroplast markers have questioned the monophyly of
