How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]
J AnatThis 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.

Global Assessment of Marine Reptiles and Mammals Using a Taxonomic Distinctness Tool: Implications for Their Conservation. [PDF]
Ecol EvolThis study examines the global distribution of marine reptiles and mammals, revealing contrasting biogeographic patterns shaped by their distinct evolutionary histories. Marine mammals exhibit non‐random distributions with elevated taxonomic distinctness in the Arctic and North Pacific, whereas marine reptiles show phylogenetic clustering in tropical ...

Iterative evolution of sympatric seacow (Dugongidae, Sirenia) assemblages during the past ~26 million years. [PDF]
PLoS ONE, 2012 Extant sirenians show allopatric distributions throughout most of their range. However, their fossil record shows evidence of multispecies communities throughout most of the past ∼26 million years, in different oceanic basins.
