“…Early Neogene marine elasmobranch assemblages known from the Americas are summarized in Figure 15 and include North America (Purdy et al, 2001;Visaggi and Godfrey, 2010), Southern South America (Suarez et al, 2006;Cione et al, 2011) and Tropical America (Leriche, 1938;Casier, 1966;MacPhee et al, 2003;Alván et al, 2006;Portell et al, 2008;Costa et al, 2009;Aguilera and Lundberg, 2010;Pimiento et al, 2013b, Laurito et al, 2014Carrillo-Briceño et al, 2016). From these assemblages the Uitpa Formation (Colombia) has been referred to the Aquitanian (Carrillo-Briceño et al, 2016), while the Calvert and Pungo River formations in North America (Purdy et al, 2001; Visaggi and Godfrey, 2010) and the Cantaure (in this work) and Castillo (Rincón et al, 2014) formations in Venezuela, have been referred to the Burdiga- lian. The remaining formations ( Figure 15) have been assigned to an unresolved early Miocene age.…”

The Cantaure Formation (Burdigalian to ?early Langhian) is located in the Falcón Basin, North Western Venezuela, and includes one of the most diverse Neogene teleostean and benthonic invertebrate faunas in Tropical America. The paleoenvironmental preferences of the members of this fauna, as well as published paleogeographic reconstructions, suggest that the Cantaure Formation was deposited in a highly-productive shallow water environment, associated with coastal upwelling. We documented a paleodiversity of 39 shark and ray species, including 15 previously unreported taxa for Venezuela and six for Tropical America. We performed a bathymetric analysis of the fossil assemblage based on the distribution of closely-related extant chondrichthyan relatives of fossil taxa and discuss the ecological role and stratigraphic significance of the latter. Our results support the hypothesis that the Cantaure Formation was deposited in an insular inner-middle shelf environment. The elasmobranch fauna is characterized by a predominance of benthopelagic sharks with piscivorous feeding preferences (e.g., †Paratodus, Galeorhinus, Hemipristis, Rhizoprionodon, Carcharhinus, Isogomphodon, Negaprion, †Physogaleus and Sphyrna) followed by durophagous/cancritrophic feeders (e.g., Heterodontus, Nebrius, Mustelus, Rhynchobatus, Pristis, Dasyatis, cf. Pteroplatytrygon, cf. Taeniurops, Aetobatus, Aetomylaeus and Rhinoptera). Filter (e.g., Mobula and †Plinthicus), eurytrophic/sarcophagous (e.g., †Carcharocles and Galeocerdo) and teuthitrophic (e.g., Alopias) feeder species were also found. Teeth of Carcharocles megalodon found in Burdigalian sediments of the Cantaure Formation support the presence of this species already in the early Miocene. Some taxa (Nebrius, Carcharhinus cf. C. macloti and Rhynchobatus) are absent from the extant Caribbean and Western Atlantic fauna, but were present in the region before the closure of the Central American Seaway.

“…In contrast, the extirpation of the kitefin shark Dalatias and the sawshark Pristiophorus from EP at the end of the Neogene is intriguing. Pristiophorus had a wider distribution in the American continent during Miocene and Pliocene times ( Carrillo-Briceño et al, 2016a ); however, only one extant species ( Pristiophorus schroederi ) with a reduced distribution, inhabits the northern most part of the TNWA province, living over continental and insular slopes between 400 and 1,000 m ( Kiraly, Moore & Jasinski, 2003 ). In the reference to Dalatias , the extant species prefers deep-water environments near the continental slope, although also it has been referred in shallower waters ( Carrillo-Briceño et al, 2016a , fig.…”

“…6). The Neogene fossil record of Dalatias and Pristiophorus in the Americas indicates that these taxa have been inhabitants of both shallow and deep-water environments ( Carrillo-Briceño et al, 2013 , 2015b , 2016a , and references therein), which could have allowed a high vagility to overcome aquatic barriers associated to sea level and habitat loss. The extirpation of Dalatias , Pristiophorus , as well other marine fauna from the EP ( Rivadeneira & Marquet, 2007 ; Villafaña & Rivadeneira, 2014 ), could be correlated with the expansion of upwelling areas and the cooling of surface waters during Pliocene–Pleistocene ( Ibaraki, 1997 ; Ravelo et al, 2004 ; Lawrence, Liu & Herbert, 2006 ; Dowsett et al, 2013 ).…”

“…These phenomena have not been studied in sharks and rays, in spite of the availability of direct empirical evidence—fossils—documenting their evolutionary history. Recent studies of the Neogene shark and ray fossil record of Tropical America documented the taxonomy and paleoecology of many assemblages ( Aguilera, 2010 ; Carrillo-Briceño, Aguilera & Rodríguez, 2014 ; Carrillo-Briceño et al, 2015a , 2015b , 2016a , 2016b ; Perez et al, 2017 ; Aguilera et al, 2017 ; Landini et al, 2017 , and references therein), making the region one of the best documented of the American continent ( Kruckow & Thies, 1990 ; Aguilera, 2010 ; Aguilera et al, 2011 , 2017 ; Carrillo-Briceño, Aguilera & Rodríguez, 2014 ; Carrillo-Briceño et al, 2015b , 2016a , and references therein).…”

We present the first comprehensive review of the present and past shark and ray diversity in marine waters of Tropical America, examining the patterns of distribution in the Eastern Central Pacific (EP) and Western Central Atlantic (WA) realms. We identified the major regions of diversity and of endemism, and explored the relations to physical variables. We found a strong relationship between shark and ray diversity with area and coastal length of each province. The Tropical Northwestern Atlantic Province is characterized by high diversity and greater occurrence of endemic species, suggesting this province as the hotspot of sharks and rays in Tropical America. The historical background for the current biogeography is explored and analyzed. Referential data from 67 geological units in 17 countries, from both shallow and deep-water habitats, across five time-clusters from the Miocene to the Pleistocene were studied. New data include 20 new assemblages from six countries. The most diverse Neogene and extant groups of shark and ray are Carcharhiniformes and Myliobatiformes, respectively. The differentiation between Pacific and Atlantic faunas goes to at least the middle Miocene, probably related with the increasing closure of the Central American Seaway acting as a barrier. The highest faunal similarity between the assemblages from the EP and the WA at the early Miocene could be related to the lack of a barrier back then, but increased sampling is needed to substantiate this hypothesis.

Elasmobranch remains are quite common in Miocene deposits and were the subject of numerous studies since the middle of the nineteenth century. Nevertheless, the taxonomic diversity of the Marine Molasse sharks, rays and skates is still largely unknown. Here, we describe 37 taxa from the lower Miocene of the Molasse Basin: 21 taxa could be identified at species level, whereas 15 taxa could only be assigned to genus and one taxon is left as order incertae sedis. The material was collected from deposits of the Auwiesholz Member of the Achen Formation (middle Burdigalian, middle Ottnangian age, ca. 17.8 Ma) exposed near Simssee, Upper Bavaria. This faunal assemblage is a mixture of shallow marine, near-coastal, pelagic and deep-water taxa. The fauna from Simssee displays different biogeographic dynamics at local and regional scales, possibly related to the intense climatic, oceanographic and tectonic events that occurred during the Eggenburgian–Ottnangian stages. The faunal relationships of the early Miocene chondrichthyan faunas from the Mediterranean Sea and Paratethys with others regions are established on the basis of qualitative (presence/absence) data. The beta diversity (Sørensen–Dice coefficient) of the Miocene Molasse elasmobranchs was used to characterize the taxonomic differentiation between localities and regions. According to our results, the fauna from Simssee shows close similarities with those from Switzerland, Austria, France and northern Germany. Faunal similarities and differences are mainly related to tectonic events and oceanographic variables (i.e. migration through seaway passages) or might represent collecting biases.
