摘要

摘要德国北部Langenberg采石场晚侏罗世（晚Kimmeridian）的一个上部“三齿齿”臼齿被认为是Morganucodonta的Storchodon cinggulatus gen.et sp.nov。磨牙的特征是连续的舌侧和颊侧扣带，以及相对较大的、向颊侧偏移的牙尖顶D，该牙尖顶未整合在颊侧扣带回中。这颗牙齿的长度为3.07毫米，比已知最大的臼齿——戴维斯Paceyodon davidi的下正模臼齿小不到10%。Langenberg morganucodontan可能代表了邻近古岛屿上岛屿巨人症的一个例子。

A Large Morganucodontan Mammaliaform from the Late Jurassic of Germany

Abstract An upper “triconodont” molar from the Late Jurassic (late Kimmeridgian) of the Langenberg Quarry in northern Germany is attributed to Storchodon cingulatus gen. et sp. nov. of Morganucodonta. The molar is characterized by continuous lingual and buccal cingula, and a relatively large, buccally-shifted cusp D which is not integrated in the buccal cingulum. With a length of 3.07 mm, the tooth is less than 10 % smaller than the lower holotype molar of Paceyodon davidi, the largest known morganucodontan. The Langenberg morganucodontan possibly represents an example of insular gigantism on an adjacent paleoisland.

期刊介绍： Fossil Imprint (formerly Acta Musei Nationalis Pragae, Series B – Historia Naturalis) is an international, open access journal, publishing original papers and reviews of any length from all areas of paleontology and related disciplines, such as palaeoanthropology, biostratigraphy, palynology, and archaeobotany/zoology. All taxonomic groups are treated, including plants, invertebrates, vertebrates, microfossils, and ichnofossils, with a special emphasis on terrestrial and post-Palaeozoic marine biota. We encourage the publication of international meetings as well as special thematic issues. The aim of the journal is to spread the scientific knowledge with no restrictions, and to allow access to it to any interested person. Each article includes information about the date of receiving, accepting and issue.
