“…The Late Pleistocene layers also contain the remains of bony fish, sharks, rays and marine reptiles as reworked elements from the Late Cretaceous carbonate rock forming the walls and ceiling of the cave (Hontecillas et al, 2015).…”

“…A collection of 10 isolated vertebrae and 16 teeth was discovered in the Calvero de la Higuera complex, near the village of Pinilla del Valle, northwest of Madrid, Spain (Hontecillas et al, 2015). The complex is a series of cave deposits known for Pleistocene mammals and hominids.…”

“…The reptile remains (which are found in association with the teeth of chondrichthyans and osteichthyans) are within Late Cretaceous dolomites and sandstones with dolomitic cement (Peréz-González et al, 2010). Based on correlation with other Late Cretaceous outcrops in the surrounding area, they are assigned to the Santonian (Alonso, 1981;Hontecillas et al, 2015). The squamate material was assigned to Carentonosaurus mineaui, which greatly extends the range of this genus, which was previously only known from the Cenomanian.…”

“…Despite these factors, recent finds have dramatically altered traditional views of the stratigraphic distribution and global range of the dolichosaurs (e.g., Haber and Polcyn, 2005;Hontecillas et al, 2015;Paparella et al, 2018). These new occurrence data indicate that our understanding of the evolution of dolichosaurs needs to be reevaluated.…”

Non-ophidian ophidiomorphs, colloquially referred to as 'dolichosaurs,' are small-bodied aquatic lizards that lived in shallow seaways, rivers, and reef environments during the Late Cretaceous. Preservational, geographic, and taphonomic biases in this group make trends in biodiversity difficult to assess. This is exemplified by the fact that the majority of the described species are monotypic and known only from single specimens, imparting very little information on morphological or spatial variation. Here we present a revision of the spatial and temporal distributions of non-ophidian ophidiomorph lizards ('dolichosaurs') from Cretaceous sediments worldwide. The fossil record of dolichosaurs begins in the Valanginian (Early Cretaceous). The late Early Cretaceous records are sparse but suggest a wide geographic distribution spanning the Tethys and Western Pacific. This is followed by a dense Cenomanian record from Tethyan and British deposits, and rarer specimens from North America. Though there is a substantial drop in the number of specimens recorded from the Turonian-Maastrichtian, these rare occurrences represent the largest geographical distribution of dolichosaurs: spanning Europe, North America, and South America before going extinct during the end-Cretaceous mass extinction. These occurrences indicate that ophidiomorphs most likely originated in the Jurassic Tethys and continued to radiate spatially and phylogenetically until the end of the Mesozoic, showing much more temporally and environmentally diverse patterns than previously indicated.

“…For example, reworked remains are exhumed from their original sediment and reburied in a new layer (Fernández López, 1991;Donovan et al, 2010). Examples of this kind of finds are numerous in the specialized literature (i.e., Donovan et al, 2010;Hontecillas et al, 2015;Crespo et al, 2016). Within those examples, the karstic reactivation recorded in the central Mediterranean area around 6 ka BP (Northgrippian, Holocene) has been related to erosive events in numerous sites of the region (Fumanal, 1986(Fumanal, , 1995, requiring the conduction of taphonomic analysis to avoid erroneous biochronological conclusions.…”

The small-vertebrates' assemblage recovered comes from Units I to IV from El Salt site (Alcoi, Spain). The sample is composed by nearly 310 remains, and includes one toad (Epidalea calamita), two lizards (Lacertidae indet. and Chalcides cf. bedriagai), two snakes (Coronella cf. girondica and cf. Coronella sp.), two insectivores (Crocidura sp. and Sorex sp.), one lagomorph (Oryctolagus cuniculus) and seven rodent taxa (Arvicola sapidus, Microtus sp., M. arvalis, M. cabrerae, M. duodecimcostatus, Apodemus sylvaticus, and Eliomys quercinus). All the species described in the present work are consistent with a Late Pleistocene-Holocene RESUMEN El conjunto de pequeños vertebrados recuperado procede de las Unidades I a IV del yacimiento de El Salt.
