“…Within the context of overall decreasing compressive tectonic activity at the central and western-central basin margins, the upward sequence from distal alluvial deposits to lacustrine carbonate sediments recorded by units T5 and T6 in the study area is consistent with a transition to a more humid climate during the deposition of the studied succession. This interpretation is supported by studies of charophytes (González-Pardos, 2012), ostracods (Martínez-García et al, 2014) and micromammals (Larrasoaña et al, 2006;Murelaga, 2000;Murelaga et al, 2002;Ruiz-Sánchez et al, 2013) in the nearby Pico del Fraile and Loma Negra sections ( Figs. 6; 15).…”

“…Regional studies indicate that the sedimentary infill of the Ebro Basin is arranged into eight stratigraphic genetic units (Tectosedimentary Units or TSUs, named T1 to T8;Muñoz et al, 2002;Pardo et al, 2004). The ages of these TSUs have been determined from vertebrate fossil assemblages (data summarized in Agustí et al, 2011;Murelaga et al, 2008;Pardo et al, 2004;Ruiz-Sánchez et al, 2013;Suarez-Hernando, 2017) and, more recently, by means of magnetostratigraphic studies on Oligocene and Miocene sediments (Barberà et al, 2001;Larrasoaña et al, 2006;Oliva-Urcia et al, 2019;Pérez-Rivarés et al, 2018;Valero et al, 2014).…”

“…1B; 6) using the biostratigraphic data provided by Martínez-García et al (2014), and considering the boundary T5/T6. In micromammal fossil sites in close areas (LN-64a, PF2, SA5 and SA6; summarized in Suarez-Hernando, 2017), the presence of Vasseuromys cristinae (Ruiz-Sánchez et al, 2013;Suarez-Hernando, 2017) has been attributed to the middle Aragonian, in local zone D and European land Mammal unit MN5 (Daams and Freudenthel, 1988;Van der Meulen et al, 2012). Located at the base of section Pico del Fraile, fossil site PF1 was attributed by Larrasoaña et al (2006) and Ruiz-Sánchez (2012) to the local zone A.…”

Stratigraphic and sedimentological study of distal alluvial and lacustrine deposits in the Plana de la Negra-Sancho Abarca area (western-central Ebro Basin, NE Iberia) within the early and middle Miocene allows five main lithofacies to be characterized and mapped within two tectonosedimentary units, construction of a sedimentary facies model and discussion on allogenic controls on sedimentation. In this area, the boundary between tectonosedimentary units T5 and T6 appears to be conformable and is marked by the change from dominant clastics to carbonates. Correlation of the studied outcrops with nearby sections that already had magnetostratigraphic and biostratigraphic data allows the studied succession to be dated from C5Dr to C5Cn (Burdigalian-Langhian), placing the boundary T5/T6 at ca.16.1-16.05Ma. Seven vertical facies sequences document deposition of distal alluvial clastics and palustrine and lacustrine carbonates. Sandstones and mudstones represent low-sinuosity channels and lateral and terminal splays by unconfined flows runnig across the alluvial plain, associated to the Pyrenean-derived Luna fluvial system. The carbonates contain charophytes, ostracods, bivalves and gastropods, indicating deposition in 2-4m deep lakes. Laminated carbonate facies record reworking of shore carbonates and the influx fine-siliciclastic sediment offshore. Abundant bioturbation and desiccation features indicate episodic submergence and subaerial exposure. Four main episodes of alluvial and associated palustrine/lacustrine facies belt shifts are identified. Alluvial deposition in the studied T5 unit is related to low lake level conditions, rather than to a Pyrenean uplift. The maximum extent of the freshwater carbonates occur at the base of unit T6. This is consistent with conditions of increasing humidity of the Middle Miocene Climatic Optimum.

“…Paradoxically, even if also rare in the fossil record, Myxomygale extends on the whole Europe (Austria, Czech Republic, Serbia, Greece and especially Germany); more frequent and abundant in northern Europe (Ziegler 2003(Ziegler , 2006(Ziegler , 2012. It extends even to Spain during the Early/to Middle Miocene (Ruiz-Sanchez et al 2012;van den Hoek Ostende et al 2016), possibly linked to the extension of humid environments (Daams et al 1988). New studies in the last fifty years made it possible to better understand the phylogenetic relationships between the different taxa, especially at generic level (Schwermann & Thompson 2015).…”

New material recovered in the Oligocene locality St-Martin-de-Castillon (Vaucluse, France; MP24) provides a better knowledge of the characteristics of the species vauclusensis in its type-locality, hitherto assigned to the genus Myxomygale (Talpinae, tribe Urotrichini). In Europe, the species assigned to Myxomygale range from Late Eocene/Early Oligocene to the end of the Middle Miocene (MN 7/8). However noticeable differences can be observed in mandibles of these taxa, sometimes even coexisting in the same localities. We propose for the plesiomorphic branch (including M. vauclusensis and M. minor) a new genus, Percymygale, closely related to Myxomygale. Percymygale is consequently also assigned to the tribe Urotrichini. Today, the tribe Urotrichini (American and Japanese shrew-moles) is composed of terrestrial, semi-fossorial species, not well adapted to digging but able to climb small bushes, and foraging in grasslands, forests and covered landscapes. As a result, their limbs protrude laterally from the body (unlike in moles) and their humeri are usually longer with very limited adaptations to digging. Humeri are poorly known for Myxomygale and only fragmentary humeri are known for Percymygale n. gen. making comparisons difficult. However the muzzle development in Percymygale and Myxomygale suggests that Myxomygale was perhaps a better burrower than Percymygale.http://www.zoobank.org/urn:lsid:zoobank.org:pub:E0BDC0FC-ABA2-4A84-AE76-06B3433B432E http://www.zoobank.org/urn:lsid:zoobank.org:act:17E4DD37-24A4-4C7A-A7FEB421CF90F89C
