Geologica Balcanica, 1994 Tithonian marine sediments from 34 boreholes and one outcrop in North Bulgaria have been palynologically examined. They contain rich anа commonly well preserved dinocyst assemblages. This paper includes brief comments on morphology, taxonomy, geographic and stratigraphic distribution of 56 dinocyst taxa and 2 acritarch species which start ill this ...

Integrative Zoology, EarlyView.This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

CALCAREOUS NANNOPLANKTON OF THE TITHONIAN OF THE EASTERN CRIMEA
Collection of Scientific Works of the Institute of Geological Sciences of the NAS of Ukraine, 2009 Впервые установлен видовой состав известкового нанопланктона в титоне восточного Крыма. Нанофоссилии встречаются редко и имеют малое видовое разнообразие. Полученные данные не дают возможности разделить титон, но позволяют проводить его границы: нижнюю – по исчезновению Stephanilithion bigoti; верхнюю – по расцвету Nannoconus.

Middle – Late Jurassic (Late Bathonian – Tithonian) Palynomorphs
Journal of Micropalaeontology, 1985 Abstract. INTRODUCTIONJurassic palynomorph assemblages have been recovered in numerous wells in northeast Libya. Jurassic rocks reflect changing sedimentary environments which have greatly influenced the composition of the palynological assemblages.In the northernmost area, Jurassic sediments unconformably overlie the Palaeozoic or Triassic and show a ...

On the Origin of the Tingidae (Insecta, Heteroptera)
Zoologica Scripta, EarlyView.ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...
