俄罗斯远东滨海边疆区南部弗伦采夫卡组的下白垩纪沉积物中描述了一个保存极其完好的本土被子植物草本群落。大库夫辛 (Bolshoy Kuvshin) 地区位于大库夫辛海角 (Bolshoy Kuvshin Cape) 乌苏里湾沿岸，靠近大卡门 (Bolshoy Kamen) 镇。植物承载层的年龄被确定为早-中期阿尔布阶。被子植物组合包括 6 个种：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 和两个新的未确定种。大多数标本都是由附有叶子或果实的分枝茎碎片或几乎完整的植物代表的。两个物种（Jixia pinnatipartita 和 Asiatifolium elegans）也存在于城子河组（中国黑龙江东部）的被子植物组合中。被子植物遗骸中还伴随着蕨类植物 Onychiopsis psilotoides，其几乎以整个幼苗为代表。这些植物化石在一次洪水事件中被掩埋，并且仍然非常靠近原来的位置。它们形成了一个先锋开放草本群落，由蕨类植物和被子植物组成，后者占主导地位，并适应在周期性洪水地区的新鲜沉积物中定居。
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.
