The biota lasted for about 10 million years, divided into two phases： the Bathonian-Callovian Daohugou phase （about 168-164 million years ago） and the Oxfordian Linglongta phase （164-159 million years ago）. The Yanliao fossils are often taphonomically exceptional （many vertebrate skeletons, for example, are complete and accompanied by preserved integumentary features）, and not only are taxonomically diverse but also include the oldest known representatives of many groups of plants, invertebrates, and vertebrates. These fossils have provided significant new information regarding the origins and early evolution of such clades as fleas, birds, and mammals, in addition to the evolution of some major biological structures such as feathers, and have demonstrated the existence of a complex terrestrial ecosystem in northeast China around the time of the Middle-Late Jurassic boundary.展开更多

It has been described as a critical link between feathered dinosaurs and birds. Recent studies, including those of Anchiornis, Xiaotingia, Eosinopteryx and Aurornis, challenged Archaeopteryx as the most basal bird. The new Anchiornis huxleyi specimens that are described in this paper show some minor different characters compared to previously reported Anchiornis specimens, which has revised the character list of Anchiornis and indicates a different phylogenetic point from former opinions.展开更多

文摘瘦魔蜂属(Leptephialtites Rasnitsyn,1975)是哈萨克斯坦晚侏罗世卡拉套生物群中魔蜂科魔蜂亚科的一个分异度比较高的类群,也曾报道于我国内蒙古宁城地区中-晚侏罗世道虎沟生物群,但没有描述和图示。本文对产自宁城道虎沟村中-上侏罗统道虎沟化石层的一块雌蜂标本进行了描述,将其归入瘦魔蜂属并建立了一新种:张氏瘦魔蜂(Leptephialtites zhangi Ding and Zhang,sp.nov.)。该新种区别于卡拉套生物群中瘦魔蜂属的所有种:前翅1-Rs脉长为其与翅痣基部距离之半(后者1-Rs脉不长于其与翅痣基部的距离),横脉1r-rs完整(后者1r-rs残存或完全消失);腹部纺锤状,最宽处在其中部(后者腹部最宽处位于其端半部)。本文还提供了瘦魔蜂属所有已知种的检索表。另外,瘦魔蜂属仅存在于卡拉套生物群和道虎沟生物群,证实了这两个生物群具有密切的关系。
