The Ribota site (Ágreda, Soria, Spain) is a new locality in the Matute Formation (Tithonian–Berriasian) composed of several carbonate layers, outstandingly rich in macrovertebrate remains. Fossils show an unusual replacement of the original bioapatite by quartz, and are found as positive reliefs protruding from lacustrine limestone beds. This type of conservation has allowed the identification of around one hundred vertebrate bone accumulations in an outcrop of more than 10 hectares. Osteichthyans (articulated partial skeletons, cranial material, and isolated postcranial bones and scales), crocodylomorphs (disarticulated cranial material, isolated teeth, vertebrae and osteoderms), turtles (partial carapaces and plastra, but also isolated plates) and pterosaurs (cranial and appendicular elements) have been identified. Around 80 specimens have been collected and a preliminary study of part of the collection (35 specimens) has allowed the identification of at least 5 different taxa: Halecomorphi indet., Neoginglymodi indet., Goniopholididae indet., Testudinata indet., and Pterodactyloidea indet. This new site represents one of the few sites from this time interval preserved in a fully lacustrine environment, so these vertebrate assemblages are unique and composed of different animals that presumably lived around and within the lake. They are dominated by aquatic and amphibian vertebrates and was formed by attrition in this lacustrine environment, possibly far from the lake shoreline. These macrovertebrate assemblages provide new data about the diversity in the faunal ecosystems from the Jurassic/Cretaceous transition of the Iberian Basin Rift System.

The Exceptional Fossil Site of Las Hoyas (SPAIN) from an Educational Perspective

International audienceThe paleontological heritage of the fossil site of Las Hoyas (Early Cretaceous of Cuenca, Spain) is becoming a relevant part of the sociocultural identity of Castilla-La Mancha autonomous community in general, and of Cuenca province in particular. The most recent scientific advances, including several fossil findings that have had high scientific impact, have made Las Hoyas to regularly be the center of attention in the local, national, and international media, especially since the reinterpretation of the paleoecosystem represented by the locality published in 2010. These results have led to a renaissance of the interest of the society for this unique site. As a consequence, Las Hoyas has been declared Site of Cultural Interest by the regional government, in the form of paleontological zone. This recognition, which grants the locality with the highest level of protection, sets a legal framework for the educative initiatives developed at this locality, which can be categorized as non-formal education, formal education, and Social Paleontology

Evolutionary time best explains the latitudinal diversity gradient of living freshwater fish diversity

The latitudinal diversity gradient is Earth’s foremost biodiversity pattern, persistent across clades and geologic time. Several recent studies have shown that diversification rates are similar among latitudes, and therefore cannot explain the latitudinal diversity gradient. An alternative explanation is that the tropics were colonized earlier than the temperate zone, allowing more time for speciation to build richness. Here we test the diversification-rate and colonization time hypotheses in freshwater ray-finned fishes, a group comprising nearly a quarter of all living vertebrate species and with a longer evolutionary history than other vertebrates. To build a global timeline for colonization and diversification, we performed ancestral area reconstructions on a time-calibrated phylogeny of all ray-finned fishes using occurrence records from over 3,000 freshwater habitats. We found that diversification rates are not systematically related to latitude, consistent with analyses in other groups. Instead, the timing of colonization to continental regions had 2–5 times more explanatory power for species richness than diversification rates. Earlier colonization explains high richness in the tropics, with the Neotropics in particular supporting the most diverse fauna for the past 100 million years. Most extratropical fish lineages colonized shortly after the end-Cretaceous mass extinction, leaving limited time to build diversity even in places where diversification rates are high. Our results demonstrate that evolutionary time, reflecting colonization and long-term persistence of lineages, is a powerful driver of biodiversity gradients.
