瑞士新生代鸟类的化石骨骼记录相当糟糕，尽管已经在20个轨迹点描述了鸟类的踪迹。我们回顾了瑞士骨骼鸟类化石，重点介绍了巴塞尔自然历史博物馆藏品中发现的新材料。该标本包括两种新的猫头鹰(条形)，一种来自戈斯根运河的晚始新世裂缝，另一种来自穆姆利斯维尔晚渐新世。始新世猫头鹰标本由部分的、远端的踝跖骨组成，因此保存得太不完整，不能允许关于其分类亲缘关系的可靠假说。然而，它确实显示出类似于已灭绝的古狗科成员的特征。渐新世标本暂时归属于少条线虫属，是已灭绝的原线虫属中最年轻的代表。根据该科首次发现的完整的足跖骨，我们建立了一个新种--贝氏寡头。这两个标本代表了瑞士首次发现的猫头鹰化石。
The fossil skeletal record of birds from the Cenozoic of Switzerland is rather poor, despite the fact that avian tracks have been described from twenty tracksites. We review the Swiss fossil skeletal avifauna with emphasis put on new material discovered in the collection of the Natural History Museum Basel. This material includes two new owls (Strigiformes), one from a Late Eocene fissure filling from the Gösgen canal, and another from the Late Oligocene of Mümliswil. The Eocene owl specimen consists of a partial, distal tarsometatarsus, and is therefore too incompletely preserved to allow for reliable hypotheses concerning its taxonomic affinities. It does, however, display features resembling members of the extinct family Palaeoglaucidae. The Oligocene specimen is tentatively attributed to the genusOligostrix, and it is the youngest representative of the extinct family Protostrigidae. Based on the first complete tarsometatarsus for this family, we erect a new species,?Oligostrix bergeri. These two specimens represent the first record of fossil owls from Switzerland.
