Abstract A new genus and species of planthopper, Lanlakawa changdaensis gen. et sp. nov., is described based on a well-preserved specimen from mid-Cretaceous Kachin (Burmese) amber. This is the ninth genus of the extinct family Perforissidae and the sixth genus of the subfamily Cixitettiginae. The new genus mainly differs from the five previously described genera in tegmen venation and the number of teeth in tibial pectens. Previous researches of sensory pits and wing-coupling apparatus are brie...

Abstract Calpionellids are a group of planktonic microfossils usually occuring in large numbers in pelagic deposits from the upper lower Tithonian to upper Valanginian, and showing a fairly uniform stratigraphic distribution all over the Tethysian Realm and in the southeastern Pacific margin. A preliminary calpionellid scheme was first proposed by Jurgen Remane in 1963 and 1971 consisting of five zones and six subzones informally named: A (A1, A2 and A3), B, C, D (D1, D2 and D), and E. This bioz...

Abstract Caenagnathids were oviraptorosaur theropods characterized by elongate hind limbs that are proposed as adaptations for either wading or enhanced cursoriality. A lack of well preserved pelvic material, however, has thus far prevented reconstruction of both the hind limb and girdle for verification of these hypotheses. Here we describe an abundance of new caenagnathid pelvic material from the Dinosaur Park Formation of Alberta, Canada. These new specimens reveal more of the anatomy of the ...

ABSTRACT Enaliosuchus macrospondylus Koken, 1883 was one of the first thalattosuchian taxa from the Cretaceous to be described. The type series includes an atlas-axis complex, remnants of three post-axial cervical vertebrae, several dorsal vertebrae, a caudal vertebra, an incomplete femur and a fragmentary sacral rib from the upper Valanginian of northern Germany. Additionally, two isolated, non-thalattosuchian, tooth crowns from the uppermost Valanginian to lowermost Hauterivian of different lo...

Abstract New material and the investigation of old collections provided some 150 specimens of Early Cretaceous brachiopods from the Mecsek Mountains, Hungary. Taxonomic evaluation resulted in the identification of some species previously unknown from Hungary and confirmed the presence of some previously described species, too. In this paper Fortunella cf. fortunae Calzada, 1985, Lacunosella hoheneggeri (Suess, 1858), Monticlarella remesi Nekvasilova, 1977, Moutonithyris moutoniana (d’Orbigny, 18...

Abstract Genus Mesotipula (Limoniidae) has been recorded to date only from Jurassic localities. This paper presents results of investigation of the Asiatic species of the genus. New fossil finds from the Lower Cretaceous of Asia increase our knowledge about the evolution and distribution of this genus and prolong its history to the mid-Cretaceous. A new subgeneric classification is proposed and a new subgenus Mesotipula (Irenatipula) is hereby established. Three fossil species are described as n...

Abstract A new genus and species of basal teleost, Kradimus asflaensis gen. et sp. nov., is described from the Cenomanian/early Turonian Akrabou Formation of Morocco. Uniquely, it possesses greatly hypertrophied pectoral and dorsal fins, with the pectoral fins longer than the body. Morphological similarities with Crossognathiformes, particularly the pachyrhizodontoid Notelops, suggest crossognathiform and possibly pachyrhizodontoid affinities. A phylogenetic analysis demonstrates that its placem...

Abstract The Kamitaki Locality in the Albian Ohyamashimo Formation in the eastern Hyogo Prefecture of southwestern Japan is among the richest Lower Cretaceous fossil egg sites in the world. So far, eggshells of five different ootaxa, one ornithopod and four theropods, have been identified from the Kamitaki Bonebed Quarry. Although previous discoveries of egg remains were limited to isolated eggshell fragments, here we report on the discovery of a nearly complete egg, several partial eggs, as wel...

Abstract The beetle species Zygadenia liui (Coleoptera: Cupedidae: Ommatinae) is found in the materials collected in the Sinuiju Formation from Paekto-dong, Sinuiju City, North Pyongan Province, Democratic People’s Republic of Korea (DPRK). This discovery extends the geographic distribution of Zygadenia in the Mesozoic.

Abstract We describe Parababinskaia douteaui sp. nov., first representative of its genus in the ‘mid’-Cretaceous Burmese amber. This genus was only known after a compression fossil from the Brazilian Crato Formation. The five other Burmese amber genera of Babinskaiidae are currently endemic to this area. This early Cretaceous antlion family remains unrecorded after the Cenomanian.
