TLDR
In this paper, a biochronological study of these sites based on an integrated study of the microfossil (calcareous nannoplankton and planktonic foraminifers) and macro-molluscs assemblages is presented.Abstract:
In the Estepona basin (Malaga, S Spain), the richest and the most diverse Pliocene sites of marine invertebrates (mostly molluscs) of the Mediterranean are found. Most of the species described up until now (~95% out of 892 identified species) occur at the Parque Antena and the Velerin Area (Velerin, Velerin-Carretera and Velerin-Antena) sites. Although molluscs are very well known, the age of these important sites is still controversial. In this paper, a biochronological study of these sites based on an integrated study of the microfossil (calcareous nannoplankton and planktonic foraminifers) and macrofossil (molluscs) assemblages is presented. The Parque Antena and Velerin-Carretera sites can be attributed to the late Zanclean (uppermost part of the early Pliocene) based on the presence of Globorotalia margaritae, Gr. puncticulata and Gr. group crassaformis (including Gr. crassaformis s.s.). Nannoplankton assemblages agree with this age, and can be attributed to the CN11b biozone of Okada & Bukry (1980) due to the presence of small Gephyrocapsa, Sphenolithus abies and Reticulofenestra pseudoumbilica. At the Velerin-Antena section, the bioindicators of the early Pliocene Gr. margaritae, Sphenolithus abies and Reticulofenestra pseudoumbilica are absent. The molluscs found in the studied sites correlate with the Mediterranean Pliocene Molluscan Unit 1 of Raffi & Monegatti (1993) (MPMU1). Finally, the coexistence of Gr. margaritae and Gr. group crassaformis in the Mediterranean domain is described for the first time.read more

Commensalism in the fossil record: Eunicid polychaete bioerosion on Pliocene solitary corals
Jordi Martinell,Rosa Domènech +1 more
TL;DR: In the fossil record, Sulcichnus occurs associated to shallow marine environments whereas their Recent counterparts are described on deep-marine corals, which is interpreted as a consequence of a change in the environmental requirements of the coral/worm pair.

TL;DR: Sanz de Galdeano and Pelaez as discussed by the authors have proposed a wide variety of tectonic models for this setting, most of them are related to delamination or to subduction with associated roll-back.

TL;DR: The assemblage provides insight into an autochthonous, Mesozoic, deep-water bivalve community, which was dominated by glass scallops and lived as epifaunal-reclining carnivores and preyed on various meiofauna, occupying a similar ecologic niche as their modern counterparts.

Oxygen isotope calibration of the onset of ice-rafting and history of glaciation in the North Atlantic region

TL;DR: The first major horizon of ice-rafting occurred at about 2.4 Myr, and was preceded by a minor pulse of icerafting at 2.5 Myr as discussed by the authors, and the carbon isotope record shows that the site has been bathed by a water mass of similar characteristics to present-day North Atlantic deep water at least since 3.5
