Myrmeleontidae (antlions) is the most species-rich family of the holometabolous order Neuroptera. Evolutionary history of this diverse lacewing family remains largely unexplored. Here we report on three new genera and four new species of antlions from the mid-Cretaceous amber of Myanmar, namely Allopteroneura burmana Lu, Zhang & Liu gen. et sp. nov., Phylloleon elegans Lu, Wang & Liu gen. et sp. nov., Phylloleon stangei Lu, Ohl & Liu gen. et sp. nov. and Nanoleon wangae Hu, Lu & Liu gen. et sp. ...

Recent study of ophthalmosaurid ichthyosaurs has brought us a number of new taxa; however, the validity of several ophthalmosaurid taxa from the Volgian (Tithonian) of European Russia still remains unclear, complicating comparisons and in some cases affecting taxonomic decisions about new contributions. A revision of the type series of all three species of Undorosaurus, erected by Efimov in 1999, reveals the potential validity of two of them. This contradicts previous research, which concluded t...

Two new species, Daohugoa longa Wang, Rasnitsyn & Ren sp. nov. and D. bella Wang, Rasnitsyn & Ren sp. nov. are described from the latest Middle Jurassic Jiulongshan Formation in north-eastern China. The new fossil evidence indicates that Daohugoa retains numerous plesiomorphies of basal Hymenoptera: an enlarged first flagellomere, complete xyelid-like venation, detached and folded laterotergites, and a laterally flattened sword-like ovipositor. Based on the combination of fossil and extant taxa,...

Chroniosuchians were a clade of non-amniotic tetrapods known from the Guadalupian (middle Permian) to Late Triassic, mainly from Russia and China. The rarity of complete or articulated remains means that relatively little is known about this group in terms of its anatomy, palaeobiology or evolutionary history. Based on a nearly complete skull with a left hemimandible, we describe the first chroniosuchian from Laos from rocks preserving the Permian–Triassic boundary in the Luang Prabang Basin, wh...

The middle to late Miocene Friasian sensu stricto, Colloncuran and Mayoan South American Land Mammal Ages (SALMAs) were established based on the mammals recovered from the Rio Frias, Collon Cura and Rio Mayo formations, respectively (southern Argentina and Chile). Records of Interatheriinae (Notoungulata) from these sediments have been known since the first contributions of Ameghino and Roth, but most of this material has only been superficially revised or is almost unstudied. Based on these old...

As for many other ammonoid groups, the Hauterivian family Crioceratitidae has been traditionally approached from a strictly typological viewpoint, leading to considerable taxonomic oversplitting. Balearites angulicostatus (d’Orbigny, 1841) and Pseudothurmannia ohmi (Winkler, 1868) are two successive species within this lineage, which are used as index species in biostratigraphy. In order to clarify the taxonomic position of the two aforementioned species, the present study carries out morphometr...

Chancelloria australilonga sp. nov. is described from the Emu Bay Shale (Cambrian Series 2, Stage 4) of Kangaroo Island, South Australia. The new species has a typical sac-like body, equipped with a meshwork of dozens of distinctive rosette-like sclerites. Each sclerite comprises one central ray and six or seven lateral rays, and is characterized by a pair of remarkably long and subparallel adapical rays. Chancelloria australilonga is one of the few chancelloriid species preserved with an apical...

The ant-like stone beetle tribe Glandulariini harbours approximately 3700 species, representing more than 70% of the extant diversity of the subfamily Scydmaeninae. Fossil records of this large tribe are rare, and are mostly confined to Eocene to Miocene amber, whereas only four genera were known from Mesozoic deposits. Here we report a new Mesozoic taxon, Pangusyndicus excavatus Yin, Zhou & Cai gen. et sp. nov., from Cenomanian Burmese amber. For the first time the ventral cephalic structures o...

Unionid bivalves are a common and widely distributed group of freshwater mussels, presumably known since the Triassic. One peculiar trait is their life cycle, with brooding of eggs in portions of the gills and release of usually fish-parasitizing larvae. The morphology of these larvae (glochidia or lasidia) is an important character for unionid classification and hence for phylogenetic reconstructions. Dispersal capacity and success of unionids through geological times is assumed to be largely a...
