An extraordinarily well-preserved autochthonous angiosperm herbaceous community is described from the Lower Cretaceous deposits of the Frentsevka Formation, southern Primorye, Far East of Russia. The locality Bolshoy Kuvshin is situated on the coast of the Ussuri Bay on the Bolshoy Kuvshin Cape near the town of Bolshoy Kamen. The plant-bearing layer was determined to be early - middle Albian in age. The angiosperm assemblage includes six species: Achaenocarpites capitellatus Krassilov et Volynets, Ternaricarpites floribundus Krassilov et Volynets, Jixia pinnatipartita S.X.Guo et G.Sun, Asiatifolium elegans G.Sun, S.X.Guo et Shao L.Zheng and two new undetermined species. The majority of specimens are represented by fragments of branching stems with attached leaves or fruits or by almost complete plants. Two species (Jixia pinnatipartita and Asiatifolium elegans) are also in the angiosperm assemblage from the Chengzihe Formation (eastern Heilongjiang, China). The angiosperm remains are accompanied by the fern Onychiopsis psilotoides which is represented by almost entire young plants. The plant fossils were buried during a single flooding event and remained very close to their original location. They formed a pioneer open herbaceous community, consisting of ferns and angiosperms with a predominance of the latter and adapted to colonize fresh sediments in periodically flooded areas.

A New Species

A new fern Birisia mandshurica, sp. nov. (Dicksoniaceae) from the lower–middle Albian Frentsevka Formation of southern Primorye, Far East of Russia is described. This species is characterized by short-creeping rhizomes with closely spaced stipes and bipinnate fronds with narrow linear pinnules. A reconstruction of B. mandshurica is proposed. It comes from the autochthonous locality of ferns and herbaceous angiosperms and was a part of pioneer open community, which occupied low flat plains between river channels. Revision of ferns, described as Acanthopteris gothanii Sze from China, shows, that these ferns belongs to Birisia alata (Prynada) Samylina. The name Acanthopteris Sze should be abandoned, due to absence of spore-bearing pinnules and poor preservation of sterile pinnules in type specimens. Based on Chinese and Russian material of good preservation, we provide emended diagnoses of the genus Birisia Samylina and its type species B. alata. Re-examination of various species of the genus Birisia revealed that this genus was widely distributed in the Cretaceous floras (from the Barremian to the Coniacian) of Eastern Siberia, New Siberian Islands, North-East and Far East of Russia, China, Japan, Alaska and Western Canada. B. alata is the most widespread species.

Holocene Sediments

The ecological structure of diatoms communities was researched from sediments of the First Razdolnaya river terrace (Southern Primorye). The obtained data allowed to establish climatic rhythmics and the related transgression-regression cycles, are typical for the area of researches. The analysis of the replacement lagoon-marine diatoms complexes by lacustrine, alluvial and marsh ones allow us to establish the amplitudes of the Japan Sea fluctuations and ingression penetration into river valley. The maximum of the ingression penetration (up to 23 km from sea-shore) toward river-valley corresponds to Holocene climatic optimum. The sea level could exceed modern on +3m at this time and influenced on the coastline formation.

Cretaceous Deposits

Highly ordered mixed-layer formations of chlorite–smectite (corrensite) and mica–smectite (rectorite) were found in the volcanogenic–sedimentary rocks of Southern Primorye. They have shown a rather narrow “living” time interval (Cretaceous–Paleogene). The associations of corrensite and rectorite with chlorite, mica, kaolinite, and laumontite have great value in labeling. Their study would determine the time and thickness parameters of sedimentation conditions, the nature of the transformation stages, the physicochemical and climatic parameters of the accumulation of the depositional material, and the geological history and stratigraphic construction of Mesozoic–Cenozoic volcanogenic–sedimentary rocks of the Primorye Region.

Tersilochines of South, Southeast and East Asia (excluding Mongolia and Japan) have been studied. Eight genera and 60 species are recorded in the region: Allophrys (2 species), Barycnemis (5 species), Diaparsis (29 species), Phradis (2 species, including 1 unidentified species), Probles (12 species, including 1 unidentified and 6 undescribed species), Sathropterus (2 species), Slonopotamus gen. nov. (2 species) and Tersilochus (6 species, including one species of the obscure status). One genus and 26 species are described as new: Allophrys bruneiensis sp. nov. (Brunei), A. occipitata sp. nov. (Vietnam, India), Diaparsis absista sp. nov. (Brunei), D. bannapeana sp. nov. (Laos), D. bolikhamsaica sp. nov. (Laos, Thailand), D. brunnea sp. nov. (Brunei), D. crenulator sp. nov. (Brunei), D. dediticia sp. nov. (Vietnam, Brunei), D. hilaris sp. nov. (Vietnam), D. karnatakana sp. nov. (India), D. labiensis sp. nov. (Brunei), D. mandibulator sp. nov. (Laos), D. minuta sp. nov. (Vietnam), D. monstrosa sp. nov. (Brunei), D. morleyi sp. nov. (Sri Lanka), D. propodeator sp. nov. (Brunei, Sarawak State of Malaysia, southern Indonesia, Laos), D. pulchra sp. nov. (South Korea), D. sarawakiensis sp. nov. (Sarawak and Pahang states of Malaysia), D. viela sp. nov. (Vietnam, Laos), D. vietnamica sp. nov. (Vietnam), D. zispina sp. nov. (Vietnam), Probles vietnamica sp. nov. (Vietnam, probably East China and south of Far East of Russia), Sathropterus secundus sp. nov. (Vietnam), Slonopotamus elephantoides sp. nov. (Laos), S. indianus sp. nov. (India) and Tersilochus granulatus sp. nov. (South Korea). Generic assignment of two species are changed: Barycnemis sanctijohanni (Rao & Kurian, 1951), new combination, and Probles (Microdiaparsis) caudate (Morley, 1913), new combination. Barycnemis dissimilis and B. tobiasi from Nepal, Diaparsis convexa from Vietnam, D. niphadoctona from Laos, and Sathropterus pumilus from India and Nepal are newly recorded from the countries. The genus Diaparsis comprises almost half of species of the tersilochine fauna of the studied region (29 species, 48%), and is a dominant genus in the Oriental Region. Keys to genera and species of Tersilochinae of South, Southeast and East Asia (excluding Mongolia and Japan) are provided.
