After collecting calcareous corpuscles from plerocercoid of Spirometra mansoni (sparganum), we evaluated the antigenic values of calcareous corpuscles binding proteins obtained from the cyst fluid of Taenia solium metacestodes. Immunoblot analysis revealed that cysticercosis patient sera strongly recognized 10 and 95 kDa calcareous corpuscles binding proteins. This result demonstrated that calc...

The oldest rocks within the Kachchh Basin belong to the sediments of Kaladongar Formation exposed in Kuar Bet, Pachchham Island (western India). The Formation’s lowest unit, the Dingi Hill Member has yielded a moderately diversified calcareous nannofossil assemblage that includes the marker species of Lotharingius contractus and Triscutum sullivanii of late Early Aalenian age associated with re...

The Cape Roberts Project was successfully completed in the austral spring of 1999 with drilling of the 939.42-m CRP-3 drillhole, located 2-km west of the CRP-2/2A drillhole. The CRP-3 core comprises a 790-m Cenozoic (glacio-) marine sequence separated from underlying Devonian basement rocks by a c. 30-mthick dolerite conglomerate of undetermined age. Here, we present the results of a palaeomagn...

The variations in assemblages of calcareous nannofossils are tracked the Dakhla and Tarawan Formations exposed at Gebel Nezzazat (central Sinai, Egypt). Five nannofossil biozones, namely NP2/3, NP4, NP5, NP6, NP7/8 identified. A distinct marker bed related to Latest Danian Event (LDE) occurs within Fm. earliest representative fasciculiths, Lithoptychius schmitzii, first just below LDE is follow...

Reticulofenestra pseudoumbilicus is a Neogene calcareous nannofossil species whose highest stratigraphic occurrence (Top) reliable biohorizon in the Pliocene, calibrated at 3.82 Ma. The present record from least Middle Miocene, within an interval around Top Sphenolithus heteromorphus, 13.53 Ma, but its lower distribution range not precisely delineated. study of assemblages sediment cores Integr...

Petrological, geochemical, and biostratigraphical investigations have been conducted on seventy-nine samples from four selected sections in Jordan to understand the factors that influenced enrichment deposition of massive phosphorite deposits. The calcareous nannofossil marker species Broisonia parca constrica Reticulofenestra bisecta, assigned 1 2 (Hawar Al Dhahikiyya), were indicative Campani...

The Late Miocene-Early Pliocene Biogenic Bloom (∼9–3.5 Ma) was a paleoceanographic phenomenon defined by anomalously high accumulations of biological components at multiple open ocean sites, especially in certain regions the Indian, and Pacific oceans. Its temporal spatial extent with available information leaves fundamental questions about driving forces responses unanswered. In this work, we ...
