“…4) is consistent with the closing of the Isthmus of Panama, which most likely took place between 3.1 and 2.8 Mya (Coates et al, 2003;Coates and Obando, 1996). This event created a permanent separation between East Pacific and Atlantic mobulids as is the case for many marine species (Lessios, 2008) including various elasmobranchs (Daly-Engel et al, 2012;Keeney and Heist, 2006;Schultz et al, 2008;Stelbrink et al, 2010).…”

a b s t r a c tManta and devil rays are an iconic group of globally distributed pelagic filter feeders, yet their evolutionary history remains enigmatic. We employed next generation sequencing of mitogenomes for nine of the 11 recognized species and two outgroups; as well as additional Sanger sequencing of two mitochondrial and two nuclear genes in an extended taxon sampling set. Analysis of the mitogenome coding regions in a Maximum Likelihood and Bayesian framework provided a well-resolved phylogeny. The deepest divergences distinguished three clades with high support, one containing Manta birostris, Manta alfredi, Mobula tarapacana, Mobula japanica and Mobula mobular; one containing Mobula kuhlii, Mobula eregoodootenkee and Mobula thurstoni; and one containing Mobula munkiana, Mobula hypostoma and Mobula rochebrunei. Mobula remains paraphyletic with the inclusion of Manta, a result that is in agreement with previous studies based on molecular and morphological data. A fossil-calibrated Bayesian random local clock analysis suggests that mobulids diverged from Rhinoptera around 30 Mya. Subsequent divergences are characterized by long internodes followed by short bursts of speciation extending from an initial episode of divergence in the Early and Middle Miocene (19-17 Mya) to a second episode during the Pliocene and Pleistocene (3.6 Mya -recent). Estimates of divergence dates overlap significantly with periods of global warming, during which upwelling intensity -and related high primary productivity in upwelling regions -decreased markedly. These periods are hypothesized to have led to fragmentation and isolation of feeding regions leading to possible regional extinctions, as well as the promotion of allopatric speciation. The closely shared evolutionary history of mobulids in combination with ongoing threats from fisheries and climate change effects on upwelling and food supply, reinforces the case for greater protection of this charismatic family of pelagic filter feeders.

The fossil record of angel sharks is reviewed with special focus on skeletal remains. A new family †Pseudorhinidae is established for two species based on complete specimens from the Late Jurassic and a possible third species based on isolated teeth. This clade is a member of the stem lineage of Squatiniformes. Squatinidae represents the crown with a reliable fossil record extending back into the Aptian based on a partial skeleton displaying characteristic morphological traits of Squatina. We also present revised morphological descriptions of the skeletal remains of †Squatina baumbergensis (Campanian of Germany) and †Squatina sp. (Miocene of Japan). In this study, we used reliable skeletal remains and a modified approach to establish the origin and divergence of the Squatiniformes and the Squatinidae. Isolated teeth are considered to be unreliable because of the poor knowledge of squatiniform dental character traits and their evolution. We estimate a 'hard' minimum age constraint of 156.2 Ma and a 'soft' maximum age constraint of 181.74 Ma for the origin of the Squatiniformes. For the crown represented by the Squatinidae, we estimate a 'hard' minimum age constraint of 114 Ma and a 'soft' maximum age constraint of 157.59 Ma. These age constraints most likely designate the timing of the origin of identifiable squatiniform and squatinid characters as currently understood rather than the origin of the Squatiniformes or the divergence between the †Pseudorhinidae and the Squatinidae. The lack of pre-Late Jurassic pseudorhinids and pre-Cretaceous squatinids probably represents an artefact because characteristic squatiniform tooth morphologies, which generally provide only a restricted set of diagnosable features, might not have yet been fully developed. Consequently, skeletal remains of neoselachians from the Early and Middle Jurassic are crucial for establishing reliable characters of stem-lineage representatives and to avoid misinterpretations resulting from transferring morphological traits of the crown to fossil groups with unresolved interrelationships, as well as sister-group relations.http://zoobank.org/urn:lsid:zoobank.org:pub:5A5FA554-C834-48E3-AE44-6F92DE9CB5F1

“…Subsequently, the emergence of the Panama Isthmus isolated the American Atlantic and the American Pacific (Musick et al, 2004;Schultz et al, 2008). Second, local speciation (Lim et al, 2010;Stelbrink et al, 2010), where amphi-American genera with species endemic to the neotropics (e.g. Sphyrna tudes vs. Sphyrna media, Squatina dumeril vs. Squatina californica) follow a geminate species pattern likely split by the Isthmus of Panama.…”

In order to investigate zoogeographical patterns of the marine elasmobranch species of Colombia, species richness of the Pacific and Caribbean and their subareas (Coastal Pacific, Oceanic Pacific, Coastal Caribbean, Oceanic Caribbean) was analyzed. The areas shared 10 families, 10 genera and 16 species of sharks, and eight families, three genera and four species of batoids. Carcharhinidae had the highest contribution to shark richness, whereas Rajidae and Urotrygonidae had the greatest contribution to batoid richness in the Caribbean and Pacific, respectively. Most elasmobranchs were associated with benthic and coastal habitats. The similarity analysis allowed the identification of five groups of families, which characterize the elasmobranch richness in both areas. Beta diversity indicated that most species turnover occurred between the Coastal Pacific and the two Caribbean subareas. The difference in species richness and composition between areas may be due to vicariant events such as the emergence of the Isthmus of Panama. It is unlikely that the Colombian elasmobranch diversity originated from a single colonization event. Local diversification/speciation, dispersal from the non-tropical regions of the Americas, a Pacific dispersion and an Atlantic dispersion are origin possibilities without any of them excluding the others.Para conocer los patrones zoogeográficos de los elasmobranquios marinos de Colombia, la riqueza de especies de Pacífico y Caribe y sus subáreas (Pacífico costero, Pacífico oceánico, Caribe costero y Caribe oceánico) fue analizada. Las áreas compartieron 10 familias, 10 géneros y 16 especies de tiburones y ocho familias, tres géneros y cuatro especies de batoideos. Carcharhinidae tuvo la mayor contribución a la riqueza de tiburones mientras que Rajidae y Urotrygonidae tuvieron la mayor contribución a la riqueza de batoideos en el Caribe y el Pacífico, respectivamente. La mayoría de los elasmobranquios estuvieron asociados con hábitats bénticos y costeros. El análisis de similitud permitió la identificación de cinco grupos de familias que caracterizan la riqueza de elasmobranquios en ambas áreas. La diversidad beta indicó que el mayor recambio de especies se produjo entre el Pacífico costero y las dos subáreas del Caribe. La diferencia en la riqueza y composición de especies entre las áreas puede ser debida a eventos vicariantes tales como el surgimiento del Istmo de Panamá. Es poco probable que la diversidad de elasmobranquios en Colombia se originara de un único evento de colonización. Eventos locales de diversificación/especiación, dispersión desde las regiones templadas de América, del Pacífico y del Atlántico son orígenes posibles que no se excluyen entre sí.
