摘要

我们研究了 Kuhn 在德国 Walbeck 地点发现的古新世(~MP 5)蜥蜴的至少部分原始材料。该采集物被认为已经遗失,但由于其重要性,在文献中一直被讨论。我们重新研究了aff.Parasauromalus paleocenicus 和 aff.Glyptosaurus walbeckensis。前者最初被归入Iguania,后者被归入Anguimorpha,尽管后来这些分类受到了一些学者的质疑。我们的研究表明,这两种动物的分类都是站不住脚的。我们认为 P. paleocenicus 这个名称是一个疑名。aff.的材料。G. walbeckensis后来被认为属于漆蜥科,也被认为是潜在的两栖类。虽然它与现代的两栖类不同,但它与一种假定的多角恐龙--Camptognathosaurus parisiensis--具有相同的特征。沃尔贝克型与该物种完全相同。由于沃尔贝克类群是在1940年描述的,根据优先原则,Camptognathosaurus parisiensis是库恩所立物种的初级异名。我们为这一形态提出了一个新的合称:Camptognathosaurus walbeckensis comb.Kuhn 所绘制的标本目前已经丢失,因此我们将其命名为来自 Walbeck 的新原型。然而,该分类群与 Polyodontobaena 有很大的不同,而且新的数据也使我们对将 Camptognathosaurus 归入 Amphisbaenia 的观点产生了怀疑。该分类群在此被暂时归入漆龙科,系统发生学分析进一步证实了这一点。此外还描述了Sincoidea的材料。

Roots of the European Cenozoic ecosystems: lizards from the Paleocene (~MP 5) of Walbeck in Germany
We studied at least part of Kuhnʼs original material of lizards from the Paleocene (~MP 5) of the Walbeck locality in Germany. The collection was considered to be lost but is consistently discussed in the literature due to its importance. We restudied the type material of aff. Parasauromalus paleocenicus and aff. Glyptosaurus walbeckensis described by Kuhn in 1940. The former was originally allocated to Iguania, the latter to Anguimorpha, though later on these identifications were questioned by several authors. We show such a classification of both cannot be upheld. P. paleocenicus resembles the morphology of lacertids showing their presence in Europe already around MP 5. We consider the name P. paleocenicus as a nomen dubium. The material of aff. G. walbeckensis was later suggested to belong to Lacertidae and also considered as a potential amphisbaenian. Although it differs from modern amphisbaenians, it shares features with one supposed polyodontobaenid – Camptognathosaurus parisiensis. The Walbeck form is identical to this species. Since the Walbeck taxon was described in 1940, the principle of priority makes Camptognathosaurus parisiensis a junior synonym of the species erected by Kuhn. We propose a new combined name for this form, Camptognathosaurus walbeckensis comb. nov. The specimen figured by Kuhn is currently lost, thus we designate a neotype from Walbeck. However, this taxon differs significantly from Polyodontobaena and new data doubt the attribution of Camptognathosaurus to Amphisbaenia. This taxon is tentatively assigned here to Lacertidae, as further confirmed by phylogenetic analyses. Material of Scincoidea is also described.

期刊介绍: Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
