How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Astrocyte properties in cetacean cortices. [PDF]
Abstract Cetacean neurons are far more extensively studied in the scientific literature than the other principal cell type of the central nervous system—glia. To help address this knowledge gap, the current study profiled astrocytes in five cetacean species—Tursiops truncatus (Tt), Orcinus orca (Oo), Ziphius cavirostris (Zc), Pseudorca crassidens (Pc),

Cellular Composition of the Brain of a Northern Minke Whale. [PDF]
Avelino‐de‐Souza et al. show that the minke whale has 3.2 billion neurons in the cerebral cortex, as predicted for a generic cetartiodactyl species, which places it and other cetaceans between monkeys and great apes in a ranking of mammal and bird species by total numbers of neurons in the pallium/cerebral cortex.

A new archaic baleen whale Toipahautea waitaki (early Late Oligocene, New Zealand) and the origins of crown Mysticeti [PDF]
A new genus and species of extinct baleen whale †Toipahautea waitaki (Late Oligocene, New Zealand) is based on a skull and associated bones, from the lower Kokoamu Greensand, about 27.5 Ma (local upper Whaingaroan Stage, early Chattian).
