New Insects (Insecta: Trichoptera,Reculida, Eoblattida) from the Mesozoic of Asia

New caddisflies, reculid and eoblattid insects from the Mesozoic of Asia are described. Caddisflies of the families Philopotamidae (Mesoviatrix paradoxa gen. et sp. nov. and Kempia piotri gen. et sp. nov.) and Polycentropodidae (Polylongevus eskovi gen. et sp. nov.) from the Upper Jurassic–Lower Cretaceous of the Kempendyai locality in Yakutia are described.

(Eoblattida: Blattogryllidae) from Iya locality (Middle Jurassic of Russia) are described.     

Structure of the inflorescence and flower ofPetalonyx linearis (Loasaceae)

Fossil chloranthoid androecia,Chloranthistemon endressii gen. et spec. nov. are described from the Upper Cretaceous (Upper Santonian or Lower Campanian) of Scania, southern Sweden. They are three-lobed and dorsiventrally flattened with all pollen sacs borne laterally and inclined toward the presumed adaxial surface. The central lobe bears two pairs of pollen sacs, the lateral lobes a single pair each. The morphology, anatomy and valvate dehiscence of the fossil androecia is very similar to that seen in extant species ofChloranthus andSarcandra, but the in situ pollen differs from that of all extantChloranthaceae in being spiraperturate. A single chloranthoid androecium from the Lower Cretaceous (Upper Albian) of Maryland, North America has a more generalized structure thanChloranthistemon endressii. It consists of three stamens that are fused at the base, and each stamen bears two pairs of oppositely positioned pollen sacs. Combined with anatomical information from recentChloranthus the Lower Cretaceous specimen suggests that the androecium in the living genus has arisen by fusion and other modifications of three separate stamens each with a normal complement of four pollen sacs. The structure of both the Upper and Lower Cretaceous androecia suggest that these fossilChloranthaceae were insectpollinated. Macrofossil evidence combined with information from dispersed pollen indicates that theChloranthaceae diversified early in angiosperm fossil history and were an important component of Mid-Cretaceous plant communities.     

The earliest known Salamanders (Amphibia,Caudata):A record from the Middle Jurassic of England

Marmorerpeton gen. nov. represented by M. kermackisp. nov. and M. freemani sp. nov., is the earliest known genus of fossil salamander from the Upper Bathonian, Middle Jurassic of Kirtlington, Oxfordshire, England. Marmorerpeton is more primitive than any other known salamander in the absence of intravertebral spinal nerve foramina in the atlantal centrum, but in other features it resembles members of the family Scapherpetontidae, neotenous salamanders otherwise known from the Upper Cretaceous and Palaeocene. The Kirtlington herpetofauna is a unique freshwater assemblage of Middle Jurassic small amphibians and reptiles, several of which represent the earliest known occurrences of their respective groups.     

The family Phryganeidae (Insecta,Trichoptera) from the Mesozoic and Cenozoic of Asia (with a brief worldwide overview of the fossil caddisfly fauna)

The following new taxa of the family Phryganeidae are described: Proagrypnia sinitsae gen. et sp. nov. from the Upper Jurassic or Lower Cretaceous of Russia (Chernovskie Kopi locality) and Baissophryganoides popovi sp. nov. from the Lower Cretaceous of Mongolia (Anda-Khuduk locality). A larval case of Folindusia (Acrindusia) phryganoides sp. nov. from the Paleocene of Russia (Arkhara–Boguchan brown coal field) is described. A worldwide overview of the records of fossil adult insects and larval cases of Phryganeidae is presented.     

Scandianthus gen.nov., Angiosperm Flowers of Gaxifragalean Affinity from the Upper Cretaceous of Southern Sweden

Structurally preserved angiosperm flowers are described fromthe Upper Cretaceous of southern Sweden. They are found in fluviatiledeposits dated, on palynological evidence, as Upper Santonianor Lower Campanian. The material studied includes two speciesof Scandianthus gen.nov. and one unnamed, related taxon. Thefossil flowers represent the best-preserved Cretaceous floralstructures available and the preservation permits detailed studyof organization and arrangement of parts. Comparison with flowersof extant angiosperms indicates a close relationship with membersof the Saxifragales. Scandianthus gen.nov. fossil angiosperm, Upper Cretaceous     

Margin feeding damage on the leaves of conifers and ginkgoales from the Mesozoic of Transbaikalia

A new approach to the formal classification of arthropod margin feeding plant damage is proposed. Several types of margin feeding traces on the leaves of Pityophyllum sp. and Ginkgoites sp. from the Upper Jurassic-Lower Cretaceous Chernovskie Kopi locality, Transbaikalia, are described as five new species in the genus Pinovulnus gen. nov.     

Sur quelques sélaciens nouveauxdu Crétacé supérieur de Bolivie: Amérique du Sud

The locality of Torotoro (Puca Group, Upper Cretaceous of Bolivia) has yielded a small shark-fauna including a new genus and five new species: Pucabatis hoffstetteri nov. gen., nov. sp., Ischyrhiza hartenbergeri nov. sp., Dasyatis branisai nov. sp., D. molinoensis nov. sp. et D. schaefferi nov. sp. The genus Pucapristis, previously described on rostral teeth, is represented by numerous oral teeth unknown until this day. The occurence of the genus Schizorhiza, already pointed out, allows to attribute the El Molino formation to maestrichtian.     

The tiny horned dinosaur Gobiceratops minutus gen. et sp. nov. (Bagaceratopidae, Neoceratopsia) from the Upper Cretaceous of Mongolia

A new horned dinosaur, Gobiceratops minutus gen. et sp. nov. (Bagaceratopidae, Neoceratopsia), from the Upper Cretaceous Baruungoyot Formation of the Khermin Tsav locality (southern Mongolia) is described based on a 3.5-cm-long skull. The nasal included in the orbital border suggests relationship between the new taxon and Bagaceratops rozdestvenskyi. It is proposed that, unlike other neoceratopsian families, the family Bagaceratopidae is of Paleoasiatic origin.     

Desertiguana gobiensis gen. et sp. nov., a new lizard (Phrynosomatidae, Iguanomorpha) from the Upper Cretaceous of Mongolia

A new lizard, Desertiguana gobiensis gen. et sp. nov., is described based on a left mandibular fragment from the Upper Cretaceous of Mongolia. Comparative analysis of mandibular structures shows that it belongs to the family Phrynosomatidae sensu Frost et Etheridge, 1988. Some questions of relationships of this family with other Iguanomorpha (Iguanidae sensu lato) are discussed.     

Pollen Organs and Seeds with Eucommiidites Pollen

The characteristic Mesozoic pollen genus Eucommiidites is described from pollen organs and seeds recovered in Cretaceous strata of North America and Europe. The pollen organs are from the lowermost Upper Cretaceous (Cenomanian) of Texas and are referred to Erdtmanitheca texensis gen. et sp. nov. They are spherical heads, composed of numerous, densely crowded, radiating pollen sacs that contain abundant well-preserved pollen. Combined LM, SEM and TEM investigations show that the pollen grains each have a distinct distal colpus flanked by two lateral colpi in an equatorial position. Pollen wall ultrastructure is gymnospermous with a thick lamellate inner layer (endexine) and an outer layer (ektexine) composed of a granular inner part and a homogeneous outer part. The endexine is thickened in the region of the colpi. Small seeds from the Lower Cretaceous (upper Berriasian to Valanginian) of Bornholm, Denmark contain abundant Eucommiidites pollen in their micropyles. The seeds are referred to Erdtmanispermum balticum gen. et sp. nov. They are ovoid, and weakly triangular in transverse section and gradually taper at the apex into an elongated tube. The megaspore membrane is granular and well developed, and apparently surrounded by three separate tissues interpreted as nucellus, a thin inner integument and a sclerified outer envelope. Eucommiidites pollen in the micropyles of the seeds has a laminated endexine and an ektexine comprising two homogeneous parts separated by a granular layer. Réévaluation of other seeds known to contain Eucommiidites pollen indicates that they share significant similarities with Erdlmanispermum and that they may have been produced by closely related plants. Comparison of “Eucommiidites plants” with other seed plants suggests that they are probably most closely related to the anthophytes comprising Bennettitales, Pentoxylales, Gnetales and angiosperms.
