摘要
比利时Bernissart的Barremian-Aptian(白垩纪)地区发现了多种放光翼类动物。其中,胸膜属(Pleuropholis germinalis n. sp.), 20世纪初被Traquair称为Pleuropholis sp.。本文对P. germinalis n. sp.进行了修订和完整的描述,并确定了它属于胸膜科植物。该新种具有一系列新的特征,即粗壮的前叶柄,其水平肢与垂直肢一样宽和高,前叶柄的后缘完全光滑,前叶柄的前叶柄与前叶柄腹侧分支的背侧和腹侧边界的距离相等(P. germinalis n. sp.的自异形),短而上翘的上颌骨,短而上翘的齿状体中部背侧的一个瘦形缺口。位于眶前方的方下颌关节,以及侧鳞片光滑的后缘。
Pleuropholis germinalis n. sp., a new Pleuropholidae (Neopterygii, Teleostei) from the Early Cretaceous of Bernissart, Belgium
ABSTRACT The Barremian–Aptian (Cretaceous) locality of Bernissart, Belgium, yielded an assemblage of various actinopterygians. Among them, is the pleuropholid Pleuropholis germinalis n. sp., initially described as Pleuropholis sp. by Traquair at the beginning of the 20th century. Here, P. germinalis n. sp. is revised and fully described, and its assignment to pleuropholids confirmed. This new species is supported by a novel combination of characters, i.e. a robust preopercle with the horizontal limb as wide and high as the vertical limb, an entirely smooth posterior edge of the preopercle, a preopercular canal at equal distance from the dorsal and ventral borders of the preopercle ventral branch (autapomorphy of P. germinalis n. sp.), a short and upturned maxilla, a leptolepid notch in the median-dorsal part of the dentary, the quadrato-mandibular articulation lying anteriorly to the orbit, and a smooth posterior edge of flank scales.
