摘要

由于有用的材料很少，我们对侏罗纪短爪龙的蜕皮过程的了解非常少。来自波兰和德国的新标本，加上以前已知的标本，让我们进一步研究蜕皮过程。Laeviprosopon laeve的标本显示了以前不知道的特征。在背甲壳上，有模式种L. laeve、L. laculatum和L. fraasi三种Laeviprosopon的蜕皮线。这就产生了关于Laeviprosopon的系统地位的问题，我们在此将其重新归入同门总科中的同门科。另外，有2个原属属的标本被转移到属属

A new approach to the systematics of Laeviprosopon (Brachyura: Homolidae), with remarks on molting process of the early brachyurans

Our understanding of the molting process in the Jurassic brachyurans is very scarce because useful material is rare. New specimens from Poland and Germany, in addition to previously known specimens, let us further investigate the molting process. Specimens of Laeviprosopon laeve reveal characters not known before. On the dorsal carapace, molting lines are confirmed in three species of Laeviprosopon : the type species L. laeve , L. laculatum and L. fraasi . This brought questions about the systematic position of Laeviprosopon , which we here reassign to Homolidae within Homoloidea. Furthermore, two specimens ascribed previously to L. sublaeve are transferred to L. fraasi

期刊介绍： Founded in 1997, Palaeontologia Electronica (PE) is the longest running open-access, peer-reviewed electronic journal and covers all aspects of palaeontology. PE uses an external double-blind peer review system for all manuscripts. Copyright of scientific papers is held by one of the three sponsoring professional societies at the author''s choice. Reviews, commentaries, and other material is placed in the public domain. PE papers comply with regulations for taxonomic nomenclature established in the International Code of Zoological Nomenclature and the International Code of Nomenclature for Algae, Fungi, and Plants.
