The Hama-Koussou Basin is one of the offset structures eastern end Benue Trough in Northern Cameroon. This sedimentary basin an asymmetrical syncline whose axis strongly shifted towards East, filled predominantly with Cretaceous deposits, has experienced at least three (3) phases sedimentation during its geological history: two (2) fluvial top and second bottom consisting conglomerate, micro-co...

An assemblage of large and robust pedunculate scalpellomorph cirripede barnacles from the Maastrichtian Kalaat Senan (Tunisia) is described, their stratigraphical position within Abiod El Haria formations noted. Four taxa are documented, three which confined to area, namely Pachyscalpellum heltzeli , Cretiscalpellum robaszynskii sp. nov. Diotascalpellum sp.; fourth, curvatum was previously reco...

Deposits spanning the Radotruncana calcarata Taxon Range Zone at the Postalm section, Northern Calcareous Alps (Austria) are examined quantitatively for foraminiferal assemblages, especially the planktonic group. This study focuses on establishing a high resolution record spanning an 800 ka long stratigraphic interval from the active continental margin of the Penninic Ocean. The Postalm section...

Body size is a useful character to unravel the biology of fossil taxa and, indirectly, palaeoenvironment in which they lived. However, reliability proxies debated, particularly among insular endemics large teeth relative body have been observed. To shed light on this issue, here we compute statistical models assess: (i) and long bone scaling (ii) dentition evolutionary dynamics anagenetic linea...

Objectives Palaeopathological analysis is key for characterising population health at the individual level and across large assemblages but rarely exploited to unite remains of disarticulated individuals. This study explores potential identification through differential diagnosis periosteal lesions in a commingled deposit, both ascertain number individuals represented provide diagnosis. Materia...
