The Karstic Habitat of Spelaeogriphaceans from the Las Hoyas Fossil Site (Upper Barremian, Serranía de Cuenca, Spain)
Fossil remains of spelaeogriphaceans (Family Acadiocarididae) are common in Las Hoyas Konservat-Lagerstätte (upper Barremian, La Huérguina Formation, southwestern Iberian Basin), although they belong to an extremely rare group in the fossil record. They have been interpreted as having inhabited karstic environments as do their contemporaneous equivalents; however, this interpretation has not been clearly proven. Based on tectonic, sedimentological, geochemical, and palaeontological data, the aim of this work is to explore the evidence for active karst processes contemporaneous with Barremian sedimentation in order to support the palaeoecological hypothesis, and to shed further light on the reconstruction of the palaeogeographical evolution of the basin.
