Abstract. The family Eschrichtiidae is presently only represented by Eschrichtius robustus, a relict species from the North Pacific. Because of the scarcity of fossil records of the Eschrichtiidae, their evolutionary history is not well understood. A finely preserved mysticete skeleton was recovered from the Lower Pleistocene (1.77–1.95 Ma) of Tokyo, Japan, in 1961. The fossil consists of a cranium, mandibles, cervical, thoracic, lumbar and caudal vertebrae, chevrons, ribs, and forelimb bones… 
A PLIOCENE GRAY WHALE ( ESCHRICHTIUS SP.) FROM THE EASTERN NORTH ATLANTIC
The gray whale Eschrichtius robustus, the only living member of the eschrichtiid lineage, currently inhabits only the North Pacific. Interestingly, however, the holotypes of both E. robustus and the
A large Late Miocene cetotheriid (Cetacea, Mysticeti) from the Netherlands clarifies the status of Tranatocetidae
TLDR
It is suggested that both groups of cetotheriids and tranatocetids should be reintegrated into the single family Cetother iidae, supported by a large phylogenetic analysis.

TLDR
Hondeklip Bay is a Zanclean, early Pliocene, locality in the Northern Cape Province of South Africa that shares a seal and cetacean taxon with Langebaanweg, which is 430 km to the south and has the first balaenid described from South Africa.
New fossil remains of the commensal barnacle Cryptolepas rhachianecti provide evidence of gray whales in the prehistoric South Pacific
Abstract. We report the finding of two partial specimens of Cryptolepas rhachianecti (Cirripedia, Coronulidae), a coronulid barnacle known only to inhabit the skin of gray whales (Eschrichtius
Recent dating of extinct Atlantic gray whale fossils, (Eschrichtius robustus), Georgia Bight and Florida, western Atlantic Ocean
TLDR
The hypothesis for the decline of the Atlantic gray whale in the late Pleistocene and the late Holocene is supported and the findings of the Eastern Atlantic Basin are augmented to better incorporate the Western Atlantic Basin into a pan-ocean understanding for the species.

Morphology and phylogenetic relationships of a new eschrichtiid genus (Cetacea: Mysticeti) from the Early Pliocene of northern Italy
TLDR
The recognition of this new eschrichtiid genus suggests that the Mediterranean trophic web of the Early Pliocene was more complex than at present and that the Neogene mysticete family-level biodiversity of the Mediterranean was higher than that currently observed in this basin.
THE OLDEST ESCHRICHTIID MYSTICETE AND A NEW MORPHOLOGICAL DIAGNOSIS OF ESCHRICHTIIDAE (GRAY WHALES)
TLDR
The morphology of the dentary is used here to emend the diagnosis of the family Eschrichtiidae and for including the above Italian specimens in this family, which allows the establishment of the new genus Archaeschrichtius from the Late Miocene of Apulia, which represents the oldest eschichtiid mysticete to be formally described up to now.
THE OLDEST RECORD OF ESCHRICHTIIDAE (CETACEA: MYSTICETI) FROM THE LATE PLIOCENE, HOKKAIDO, JAPAN
Abstract A new eschrichtiid mysticete was recovered from the Late Pliocene Yuchi Formation, Teshio Town, Hokkaido, Japan. The specimen is relatively well preserved, comprising a posterior part of the
Taxonomic revision of Isocetus depauwi (Mammalia, Cetacea, Mysticeti) and the phylogenetic relationships of archaic ‘cetothere’ mysticetes
TLDR
A basal position of the genus Parietobalaena is supported in the radiation of Miocene ‘cetotheres’, the monophyly of Balaenoidea (Neobalaenidae and Balaenidae), Baloenopteroidea, and Cetotheriidae, and the paraphyly of ‘ cetothetes’s’.
A New Baleen Whale (Mysticeti: Cetotheriidae) from the Earliest Late Miocene of Japan and a Reconsideration of the Phylogeny of Cetotheres
TLDR
A new, well-preserved mysticete fossil is described and diagnosed here as Joumocetus shimizui, and it is suggested that the Isanacetus-group is a paraphyletic taxon that includes the ancestors of two clades, Balaenopteridae + Eschrichtiidae and the Cetotheriidae sensu stricto.

TLDR
A parsimony analysis of 101 morphological characters of the skull, auditory area and dentary tested on 23 taxa confirms the paraphyly of the Cetotheriidae as traditionally defined and suggests that six of the studied fossil baleen mysticetes constitute a clade.

Balaenopteroids (Balaenopteridae + Eschrichtiidae) are a diverse lineage of living mysticetes, with seven to ten species divided between three genera (Megaptera, Balaenoptera and Eschrichtius).
