[HTML][HTML] Diversity and paleoenvironmental implications of an elasmobranch assemblage from the Oligocene–Miocene boundary of Ecuador
The occurrence and diversity of elasmobranchs from the Oligocene–Miocene boundary from
Tropical America is poorly known in comparison with the paleodiversity from younger
Neogene intervals of the region. Here we describe a new elasmobranch assemblage from
the rich fossil site of Montañita-Olón (Dos Bocas Formation, Santa Elena, Ecuador), where
other vertebrates have already been described: for example, sea turtles and cetaceans. We
report a total of 27 elasmobranch taxa, 19 of which are new fossil records for Ecuador, 10 …
