The early Miocene charadriiform bird Becassius charadriioides De Pietri and Mayr, 2012, from the Saint-Gérand-le-Puy area in France, was originally described as a member of uncertain affinities within the shorebird clade Scolopaci (jacanas, seedsnipe, painted-snipe, sandpipers, and allies). Following a re-assessment of the material attributed to this taxon and in the context of a larger comparative sample of extinct and extant charadriiform birds, we conclude that it is a member of the Glareolidae (pratincoles and coursers). We also demonstrate that certain elements, such as the coracoid, which were only tentatively referred to B. charadriioides, are very likely to belong to this taxon. We describe for the first time a tarsometatarsus that we tentatively attribute to this species. Based on the morphology of the humerus and other elements, it is not possible to associate Becassius charadriioides with any extant lineage within Glareolidae; it displays a combination of morphological features that can be presumed to be ancestral to Glareolidae based on outgroup comparisons and on the distinctiveness of B. charadriioides among other glareolids. The referral of Becassius charadriioides to Glareolidae bridges a gap in the evolutionary history of the clade, attesting to the presence of members of this clade in Europe during the earliest Miocene. Additionally, we provide a review of the fossil record of Glareolidae and re-assess some of the oldest fossils to have been attributed to this group.

Becassius charadriioides，一种来自法国的中新世早期类普拉提康洛尔鸟：评述了Glareolidae的早期进化史（Aves，Charadriiformes）

来自法国Saint-Gérand-le-Puy地区的中新世早期畸形鸟Becassius charadriioides De Pietri和Mayr，2012年，最初被描述为the鸟科Scolopaci进化枝中的亲和力不确定的成员（美洲印第安人，种子刺，画刺，矶pi和盟友）。在重新评估归因于该分类单元的材料之后，并在更大范围的已灭绝和现存charadriiform鸟类的比较样本的背景下，我们得出结论，它是Glareolidae（pr科和course行者）的成员。我们还证明了某些元素，例如喙突，仅被暂时称为B. charadriioides，很可能属于这个分类单元。我们首次描述了暂定归因于该物种的酒石ta。基于肱骨和其他元素的形态，不可能将Becassius charadriioides与Glareolidae内任何现存的谱系联系起来。它显示了多种形态特征的组合，这些形态特征可以根据群体比较和B. charadriioides在其他油囊中的独特性，推测为Glareolidae的祖先。推荐的Becassius charadriioides到Glareolidae的进化枝弥合了进化枝进化史上的空白，这证明了中新世最早出现在欧洲的该进化枝的成员。此外，我们提供了Glareolidae的化石记录的回顾，并重新评估了一些归因于该类的最古老的化石。
