L'analyse sporopollinique de dépôts continentaux néogènes situés dans la zone de Belorado, province de Burgos,bordure NE du Bassin du Duero, suggère une végétation arborée associée à un tapis herbacé, qui constitue des ceintures autour d'aires aquatiques restreintes (environnements palustres, lacustres). Les caractéristiques des associations de palynomorphes permettent de définir un climat tempéré...
Amussiopecten baranensis (Almera & Bofill, 1896), of the Family Pectinidae, is widespread in Miocenemarine sediments from northeastern and southeastern Spain, ranging in age from Early Langhian to Middle Messinian. The shell consists of an outer homogeneous and foliated layer composed of low-magnesium calcite, a middle layer aragonitic, and an inner foliated layer of low-magnesium calcite. Both...
Bioerosion traces from six rocky shore localities in the Miocene Tarragona basin are described. The bioerosion affects Jurassic and Miocene carbonate substrates. The ichnotaxa include borings produced by bivalves (Gastrochaenolites and Phryxichnus), sponges (Entobia), annelids (Maeandropolydora) and sipunculids (Trypanites). Phryxichnus is recorded for the first time in the Miocene. Trace fossil assemblages,...
The stratigraphic sequence of fossil mammal localities in the type area of the Aragonian, as proposed by Daams et al. (1999) is analyzed and found to be incorrect. The sequence published by Daams et al. (1988) is the correct one, and the many new localities mentioned by Daams et al. (1999) should be placed in that sequence. The interpretation of the evolution of Democricetodon and Fahlbuschia by Van...
A new Miocene shrew from east Central Spain is described. The new form, named Turiasorex pierremeini nov. gen., nov. sp., was found in 13-10–Ma old sediments of the Calatayud-Daroca and Teruel basins. It is characterized by an extreme dental morphology consisting of elements with low length-width ratios, implying a relatively short snout. Such an adaptation could point to a hypogeal life style – using...
