Diversity, 2023 The early diverging, dolphin-sized, cetacean clade Xenorophidae are a short-lived radiation of toothed whales (Odontoceti) that independently evolved two features long thought to be odontocete synapomorphies: the craniofacial and cochlear morphology ...

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT In 2024, an expedition was conducted off northwestern Baja California, México, to find and identify the beaked whale species that produced the BW43 echolocation pulse previously recorded in this area and elsewhere in the North Pacific. There were five Mesoplodon sightings and 21 BW43 acoustic detections on both a towed array and drifting pole ...

Review of the tetrapod skull–neck boundary: implications for the evolution of the atlas–axis complex
Biological Reviews, Volume 100, Issue 6, Page 2435-2470, December 2025.ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

Frontiers in Ecology and Evolution, 2023 Teeth are often the first structures that anatomists and paleontologists examine to understand the ecology and morphology of feeding, both because teeth are highly specialized structures that provide precise information, and because they are among the ...

Comparative Anatomy of the Bony Labyrinth (Inner Ear) of Placental Mammals. [PDF]
PLoS ONE, 2013 BACKGROUND:Variation is a naturally occurring phenomenon that is observable at all levels of morphology, from anatomical variations of DNA molecules to gross variations between whole organisms. The structure of the otic region is no exception.

Molecular Ecology, Volume 34, Issue 24, December 2025.ABSTRACT The marine environment comprises vast regions without physical barriers to movement, making the understanding of population isolation and the evolution of diversity challenging. This is especially the case for highly mobile marine species.

Experimental Physiology, Volume 110, Issue 12, Page 1917-1927, December 1, 2025.Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...

Phylogeny and adaptive evolution of the brain-development gene microcephalin (
BMC Evolutionary Biology, 2011 Background Representatives of Cetacea have the greatest absolute brain size among animals, and the largest relative brain size aside from humans. Despite this, genes implicated in the evolution of large brain size in primates have yet to be surveyed in ...

Rivista Italiana di Paleontologia e Stratigrafia, 1997 An incomplete skull of Hemisyntrachelus sp. (Cetacea, Delphinidae) is described from the Piacenzian clayey marls of Rio Stramonte (Piacenza, Italy). The new find confirms the abundance of Hemisyntrachelus in the peri-Adriatic area during the Pliocene.
