最近的发现确立了缅甸的Albian-Cenomanian琥珀（缅甸琥珀）是中生代隐花植物的重要来源。在这里，我们描述了一个包含在缅甸琥珀作为原frullania cornigera gen. et sp. nov.在现存的家庭Frullaniaceae（Porellales，Jungermanniopsida）。诊断特征包括其孵化叶由一个背叶和一个腹侧小叶组成，形成一个水囊，和带状，突出的下叶产生一个假根束从长，窄盘的最上部部门。树皮碎片连接到一些假根束提供的证据表明，化石是一种附生植物。(C)2017爱思唯尔有限公司版权所有
Recent findings established the Albian-Cenomanian amber of Myanmar (Burmese amber) as an important source of Mesozoic cryptogams. Here, we describe an inclusion within Burmese amber as Proto-frullania cornigera gen. et sp. nov. in the extant family Frullaniaceae (Porellales, Jungermanniopsida). Diagnostic characters include its incubous leaves consisting of a dorsal lobe and a ventral lobule forming a watersac, and strap-shaped, prominent underleaves producing a rhizoid bundle from the uppermost sector of the long, narrow disc. Bark fragments connected to some of the rhizoid bundles provide evidence that the fossil was an epiphyte. (C) 2017 Elsevier Ltd. All rights reserved.
