Abstract The Yola Sub-basin represents the lower portion of bifurcated Upper Benue Trough, whose origin has been linked to opening Atlantic Ocean in Mesozoic. sub-basin fill consists predominantly siliciclastic and carbonate deposits, ages which have remained controversial until now. This work employs field observations integrated with palynostratigraphy refine stratigraphy these Cretaceous dep...

Collections made by Máximo Ruiz de Gaona and Luis Via Boada between 1940 and 1982, from the Albian-Cenomanian reefal limestones at Monte Orobe (Navarra, northern Spain), now housed at the Museo Geológico del Seminario de Barcelona together with newly recovered material, have enabled the recognition of two new primitive crabs. A new genus, Viaia n. gen. (type: Viaia robusta n. sp.), is compared ...

A new genus and species of leptopodid bug, Grimaldinia pronotalis Popov & Heiss is described and illustrated from Burmese Middle Cretaceous (Albian-Cenomanian) amber originating from the northern Myanmar's Kachin State. This is the second finding of Leptosaldinae (Leptopodidae), after Poinar published on Palaeoleptus burmanicus from Burmese amber in 2009.

carbonate successions of the sarvak formation (late albian? to mid-turonian) together with the carbonate of the ilam formation formed the second important hydrocarbon reservoirs in sw iran and persian gulf. facies analyses were carried out on the upper parts of the sarvak formation in western part of the ahwaz oilfield (az-63 well) to interpret depositional environment. lithologically, the uppe...

the aitamir formation (albian- cenomanian) in the kopet- dagh basin consists of fine to medium grained sandstone, siltstone, shale and limestone. its lower contact with the sanganeh formation is gradual and its upper contact with the abderaz formation is unconformable. field and petrographic studies of the aitamir formation in artenj and ghorghoreh sections, located in bazangan area- east of ko...

The Cretaceous family Spathiopterygidae (Hymenoptera: Diaprioidea), containing five species in four genera, showed a wide distribution from the upper Barremian to Turonian. We describe two new representatives of Albian San Just outcrop eastern Iberian Peninsula that correspond Diameneura marveni gen. et sp. nov. Santer and Álvarez-Parra female member Mymaropsis turolensis Engel Ortega-Blanco, 2...

Ectaetia capdoliensis sp. n., first Cretaceous and oldest representative of the scatopsid subfamily Ectaetiinae, is described from the Late Albian / Early Cenomanian amber of southwestern France. This fossil demonstrates the remarkable morphological stability of these flies since at least the mid-Cretaceous. It suggests the presence of rotten wood under wet palaeoenvironment for the correspondi...
