Late Paleozoic microfaunas in the pebbles of the Podlipoglav conglomerate, Central Slovenia
Abstract The Paleozoic conglomerate at Podlipoglav in the transitional area between the External and Internal Dinarides of Slovenia contains limestone pebbles that have been examined micropaleontologically. The recovered conodont faunas are marked by the obvious absence of shallow-water taxa. The Lower to Middle Devonian faunas are characterized by relatively abundant polygnathids that are assigned to the Emsian and early Eifelian excavatus-nothoperbonus, laticostatus and costatus Zones. The Pennsylvanian conodont faunas contain relatively deep-water Neolochriea or gondolellids indicating an early Bashkirian and Moscovian age. A presence of the radiolarian species Pseudoalbaillella nodosa s…
There is no general model for occlusal kinematics in conodonts
Knowledge of conodont element function is based largely on analysis of morphologically similar P-1 elements of few comparatively closely related species known from abundant articulated remains. From these, a stereotypical pattern of rotational occlusion has been inferred, leading to the suggestion that this may represent a general model for ozarkodinin P-1 elements at the very least. We test the generality of this occlusal model through functional analysis of Pseudofurnishius murcianus P-1 elements which, though superficially similar to homologous elements in gnathodids, evolved their platform morphology independently, through a different mode of morphogenesis, and in a different topologica…
