The extinct giant shark Otodus megalodon is the last member of the predatory megatoothed
lineage and is reported from Neogene sediments from nearly all continents. The timing of …

The stratigraphy, age, lithology, and vertebrate fauna of all 56 pre-Pleistocene fossil
Cetacea-bearing localities in Australia are reviewed. The majority of these localities occur in …

The taxonomic origin of the white shark, Carcharodon, is a highly debated subject. New
fossil evidence presented in this study suggests that the genus is derived from the broad …

The Subclass Elasmobranchii is widely considered nowadays to be the sister group of the
Subclass Holocephali, although chimaeroid fishes were originally classified as …

Fossil bioapatite may yield biogeochemical signals of paleoenvironments captured by living
organisms. Bioapatite may be diagenetically altered, however, with ions added or removed …

The early evolution of toothless baleen whales (Chaeomysticeti) remains elusive, despite a
robust record of Eocene–Oligocene archaeocetes and toothed mysticetes. Eomysticetids, a …

A diverse vertebrate fauna, dominated by elasmobranch taxa, was collected from the upper
Oligocene (Chattian) Chandler Bridge Formation in Summerville, Dorchester County, South …

Otodontids include some of the largest macropredatory sharks that ever lived, the most
extreme case being Otodus (Megaselachus) megalodon. The reasons underlying their …

We studied the feasibility of using laser ablation inductively coupled plasma mass
spectrometry (LA–ICPMS) for U-Pb dating of vertebrate and invertebrate apatite fossils. Two …

The teeth of two megatooth macro-predatory shark species (Carcharocles chubutensis and
Carcharocles megalodon; Otodontidae, Chondrichthyes) occur within the Miocene …
