The northward-flowing Humboldt Current hosts perpetually high levels of productivity along
the western coast of South America. Here, we aim to elucidate the deep-time history of this …

The diversity of the dolphin family was established during a short window of time. We
investigated delphinid skull shape evolution, mapping shapes on an up-to-date nuclear …

Several aspects of the fascinating evolutionary history of toothed and baleen whales
(Cetacea) are still to be clarified due to the fragmentation and discontinuity (in space and …

The hyoid apparatus is essential for underwater feeding in marine tetrapods, but it is unclear
whether this complex has evolved as convergently as other traits, such as dentition or …

Toothed whales (odontocetes) emit high-frequency underwater sounds (echolocate)—an
extreme and unique innovation allowing them to sense their prey and environment. Their …

All extant toothed whales (Cetacea, Odontoceti) are aquatic mammals with homodont
dentitions. Fossil evidence from the late Oligocene suggests a greater diversity of tooth …

Studies involving anatomical description and taxonomy of fossil odontocetes offer insights
into their evolutionary history and diversity. This study analyses tusk-like teeth in …

The modern sperm whales Kogia and Physeter (superfamily Physeteroidea) represent
highly disparate, relict members of a group of odontocetes that peaked in diversity during the …

Herein we describe a new finding of a medium-sized sperm whale from the Burdigalian
(Lower Miocene) of the Pietra leccese formation (southern Italy) on the basis of a partly …

The moderately rich past diversity of the superfamily Inioidea (Cetacea, Odontoceti) in both
the Atlantic and Pacific oceans contrasts with the present survival of a single genus (Inia …
