A botanical view of the ‘Baltic amber forest’: new evidence from seed plants, lichens and fungi
Baltic amber forms the largest amber deposit on earth and it is particularly well-known for the plethora of arthropod inclusions. The floristic composition, habitat types and climate of its Eocene source area, however, are still controversial. The differing suggestions range from early Eocene tropical to late Eocene temperate environments, and from lowland to montane forests. We screened a large number of inclusions from historic collections and from recently discovered amber pieces and found many inclusions of seed plants, lichens and microfungi that provide important insights into habitat structure and climate.Peer reviewe
Osmyloberotha, an unusual new genus of beaded lacewings (Neuroptera: Berothidae) from Burmese amber
Khramov, Alexander V. (2021): Osmyloberotha, an unusual new genus of beaded lacewings (Neuroptera: Berothidae) from Burmese amber. Zootaxa 5060 (2): 245-249, DOI: https://doi.org/10.11646/zootaxa.5060.2.
Sciadopitys cladodes from Eocene Baltic amber
The Baltic amber deposit represents the largest accumulation of any fossil resin worldwide and hundreds of thousands of entrapped arthropods have been recovered so far. The source plants of Baltic amber, however, are still controversial, and the botanical composition of the Baltic amber forest' remains poorly studied. Here, we provide the first unequivocal Baltic amber inclusions of the umbrella pine Sciadopitys (Sciadopityaceae), a genus that has been suggested as the source of succinite (the main variety of Baltic amber) based on chemical analyses. As previously suggested sciadopitoid inclusions must be reconsidered as being notional, representing angiosperm leaves instead, the new fossils are the first unambiguous macrofossil evidence of Sciadopitys from the Baltic amber forest', and the first pre-Oligocene macrofossil record of Sciadopitys from Europe. The fossil Sciadopitys cladodes provide new insights into the conifer diversity of the Baltic amber forest' and broaden the picture of its palaeoecology, indicating the presence of humid swamp to raised bog habitats.

Graminids from Eocene Baltic amber
We report the first bona fide graminid spikelet inclusions found in Eocene Baltic amber. The most informative anatomically preserved specimen is assigned to the genus Rhynchospora Vahl (Cyperaceae), whereas two others show affinities with sedges (Cyperaceae) or grasses (Poaceae). Examination of historic descriptions of putative graminid inclusions from Baltic amber suggests that one is of coniferous origin, while the affinities of the other fragmentary specimens remain uncertain as they have been lost. The graminid inclusions described here challenge previous notions of the Baltic amber source area being a dark, close canopy forest and rather indicate at least some open and light habitats with swampy and wet areas within the 'Baltic amber forest', and thus enlighten its hitherto obscure palaeoenvironment and floristic composition.

The fossil hornwort described from Dominican amber is an angiosperm flower
Hornworts (Anthocerotophyta) are a main lineage of land plants but they are exceedingly rare as fossils. The only fossil hornwort described from amber has been interpreted as the best preserved fossil of this group. Reinvestigation of this fossil revealed that this Miocene amber inclusion represents a poorly preserved flower that shows some features of the Caesalpinioideae subfamily of the Fabaceae.
