Limited visual perception in aquatic environments has driven the evolution of diverse
sensory modalities in aquatic mammals. Dolphins largely use echolocation for prey capture …

Abstract During the Mesozoic, Crocodylomorpha had a much higher taxonomic and
morphological diversity than today. Members of one particularly successful clade …

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

Crocodylomorpha, which includes living crocodylians and their extinct relatives, has a rich
fossil record, extending back for more than 200 million years. Unlike modern semi‐aquatic …

Throughout their evolution, tetrapods have repeatedly colonised a series of ecological
niches in marine ecosystems, producing textbook examples of convergent evolution …

Marine amniotes have played many crucial roles in ocean ecosystems since the Triassic,
including predation at the highest trophic levels. One genus often placed into this guild is the …

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 …

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 …

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