A critical revision of the fossil record, stratigraphy and diversity of the Neogene seal genus Monotherium (Carnivora, Phocidae) [PDF]

open access: yesRoyal Society Open Science, 2018
Historically, Monotherium had been one of the few genera of extinct Phocidae (true seals) that served as a wastebin taxon. Consequently, it did neither aid in understanding phylogenetic relationships of extinct Phocidae, nor in understanding seal ...

The Neogene: Part 2 Neogene geochronology and chronostratigraphy

open access: yesGeological Society, London, Memoirs, 1985
SummaryWe present a revised Neogene geochronology based upon a best fit to selected high temperature radiometric dates on a number of identified magnetic polarity chrons (within the late Cretaceous, Paleogene, and Neogene) which minimizes apparent accelerations in sea-floor spreading.

Remarks on the Oligo-Miocene extensional episode(s) in InnerDinarides: Towards the tectonic constraints of the origin of intra-montagne basins [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2022
The ongoing interest in the complex geology of the Dinaric orogen, in particular, its immediate, post-orogenic evolution (post-Lutetian), has produced a number of the tectonic solutions, proposing either extensional stage followed by the subsidence ...
