摘要树木化石树脂在微观上保真地保存了大量的动物、植物、真菌和微生物。保存在一块琥珀中的化石生物在地球历史上生活在同一时间，甚至大多生活在相同的栖息地，但它们不一定是同一相互作用的群落的一部分。在这里，我们报道了一块中新世多米尼加琥珀的原位保存的皮质群落，这块琥珀由一片地衣、一片苔藓和三种多叶地钱组成。该种地衣隶属于金缕梅科(Ramalinaceae，Lecanorm)叶霉属(Phyllopsora)，定名为P.Magna Kaasalainen，Rikkinen&A.R.Schmidt sp.11月苔藓，Aptychellites fossilis Schäf.-Verw.，HedenäS，Ignatov&Heinrichs gen.&sp.Nov.，与金雀花科现存属Aptychella相似。这三种叶地钱包括已灭绝的Lejeuneaceae Cheillejeunea antiqua(Groll)Ye&朱，2010和Lejeunea miocenica Heinrichs，Schäf.-Verw.，M.A.M.Renner&G.E.Lee sp.。11月和已灭绝的Radulaceae种Radula intecta M.A.M.Renner，Schäf.-Verw.和海因里希(Heinrichs sp.)11月5个相关的已灭绝隐花植物物种的存在，其中4个属于现存属，进一步证实了自中新世早期以来加勒比地貌类型多样性停滞不前的概念，但物种有一定的更替。
ABSTRACT Fossil tree resins preserve a wide range of animals, plants, fungi and microorganisms in microscopic fidelity. Fossil organisms preserved in an individual piece of amber lived at the same time in Earth history and mostly even in the same habitat, but they were not necessarily parts of the same interacting community. Here, we report on an in situ preserved corticolous community from a piece of Miocene Dominican amber which is composed of a lichen, a moss and three species of leafy liverworts. The lichen is assigned to the extant genus Phyllopsora (Ramalinaceae, Lecanoromycetes) and is described as P. magna Kaasalainen, Rikkinen & A. R. Schmidt sp. nov. The moss, Aptychellites fossilis Schäf.-Verw., Hedenäs, Ignatov & Heinrichs gen. & sp. nov., closely resembles the extant genus Aptychella of the family Pylaisiadelphaceae. The three leafy liverworts comprise the extinct Lejeuneaceae species Cheilolejeunea antiqua (Grolle) Ye & Zhu, 2010 and Lejeunea miocenica Heinrichs, Schäf.-Verw., M. A. M. Renner & G. E. Lee sp. nov. and the extinct Radulaceae species Radula intecta M. A. M. Renner, Schäf.-Verw. & Heinrichs sp. nov. The presence of five associated extinct cryptogam species, four of which belong to extant genera, further substantiates the notion of a stasis in morphotype diversity, but a certain turnover of species, in the Caribbean since the early Miocene.
