“…Beaked whales (Ziphiidae) are a successful family of echolocating toothed whales, whose many medium to largesized extant species are known to feed on deep water oceanic squid and fish that they capture via suction in meso-to benthopelagic regions worldwide (Heyning & Mead, 1996;Tyack et al, 2006;McLeod, 2018). While no extant beaked whale can be considered a permanent resident of the shallow southern North Sea (McLeod et al, 2006), a surprisingly high number of extinct ziphiid species are recorded from Neogene continental shelf deposits of the North Sea, in Belgium (Cuvier, 1823;Melville, 1851;du Bus, 1868;Abel, 1905;Bianucci & Post, 2005;Lambert, 2005;Lambert & Louwye, 2006;Lambert & Louwye, 2016), the Netherlands (Bosselaers, 2014; Olivier LAMBERT D.O.

“…Consequently, despite such an increasingly rich fossil record, it remains difficult to properly assess the evolution of the diversity of this highly successful cetacean family through time, the lack of temporal resolution preventing from adequately testing proposals for radiation events and extinctions. Nevertheless, new developments including the in situ discovery of additional specimens (Bosselaers et al, 2004;Ramassamy, 2016), isotopic analyses of fossil bones and attached minerals ( 187 Os/ 188 Os; Nozaki et al, 2017;14 C;Lambert et al, 2018), and palynological analyses of sediment associated with fossil remains (Lambert & Louwye, 2006;Lambert & Louwye, 2016;Miján et al, 2017) provide directions for future improvements. Focusing on the southern North Sea, recent works suggest that ziphiids occupied this region in a time interval ranging from the Middle Miocene to the Early Pliocene.…”

Extant beaked whales (family Ziphiidae) are deep diving suction feeders and none of them can be considered as a permanent resident of the shallow southern North Sea. The rich fossil record of ziphiids from Neogene deposits of this area is thus surprising. However, chronostratigraphic intervals of most recorded taxa remain poorly constrained, preventing from assessing the evolution of their local diversity. In this work, we describe a new ziphiid cranium from the Neogene of Antwerp (north of Belgium), which is attributed to Caviziphius aff. C. altirostris. Sediment samples were extracted from 15 fossil ziphiid cranial remains from this area (including the one described herein), referred to eight species. The samples were analysed for their palynological content, leading to improved chronostratigraphic ranges for several species. Seven to eight ziphiid species from the southern North Sea, all from the Messapicetus clade, are proposed to originate from a Serravallian to Tortonian (late Middle to early Late Miocene) interval, and three to six more precisely from the mid- to late Tortonian. Added to the fossil record of other regions, these results point to a Late Miocene radiation of members of the Messapicetus clade, possibly related to the synchronous worldwide decline of several hyper-longirostrine dolphin clades.

“…The family Ziphiidae is a clade among Odontoceti (Cetartiodactyla, Cetacea) represented by 23 extant species [ 1 , 2 ] and almost the same number of extinct species [ 3 , 4 ]. Although extant ziphiids have a cosmopolitan distribution, they are among the most mysterious groups of whales because of their deep-diving behaviour.…”

The oldest fossil record of the extant genusBerardius(Odontoceti, Ziphiidae) from the Middle to Late Miocene boundary of the western North Pacific

A new species of a beaked whale that belongs to the extant genus Berardius is described from the Middle to Late Miocene boundary age Tsurushi Formation ( ca 12.3–11.5 Ma) on the Sado Island, Niigata Prefecture, Japan. The new species, Berardius kobayashii sp. nov. represents the oldest record of this genus and provides a minimum age for the emergence of this extant genus. Berardius kobayashii sp. nov. has the following generic characters: the ratio between the width of the premaxillary crests and the width of the premaxillary sac fossae is 1.0–1.25, nodular frontals make isolated protuberance on the posterior part of the vertex. Among the species within the genus, B. kobayashii sp. nov. shares a unique character with B. minimus : the apices of the left and right hamular processes of the pterygoids contact medially, forming together a posteriorly directed medial point. In addition, B. kobayashii sp. nov. displays a unique combination of the following characters: it is extremely small in size, and the nasals are short, the ratio between the length of the medial suture of nasals on the vertex and the maximum width of nasals is less than 0.4. Berardius kobayashii sp. nov. fills the gap between the origin of the genus and later diversifications of the extant species. This discovery is also key to elucidate the process of the emergence and dispersal of the genus during the Middle to Late Miocene. Based on the distributional patterns of the fossil and extant species of the genus, the western North Pacific including the Sea of Japan may have been one of the areas for the evolution and radiation of this genus at the time before 11 Ma.

The finding of significant vertebrate remains inside commercial stone blocks is relatively rare. Here we describe a fossil cetacean skull discovered inside two slabs cut from a limestone block of Tortonian (i.e., early late Miocene) age from Menorca (Balearic Islands, Spain); this find represents the third record of a fossil cetacean from this island, as well as the best preserved. Unlike similar cases in the past, the Menorca skull was not extracted mechanically from the stone matrix, being rather imaged by means of computed tomography. The resulting 3D reconstruction of the skull allows us to refer the studied skull to the extant odontocete family Ziphiidae (beaked whales) and sheds light on the morphology of very delicate structures (e.g., the thin pterygoid hamuli and the mesorostral cartilage) that would likely have been destroyed during traditional mechanical preparation. This non-invasive investigation permits detailed osteoanatomical comparisons between the Menorca specimen and other extinct ziphiids, leading to the referral of the former to the stem beaked whale Messapicetus cf. longirostris. We then review the geographic distribution of fossil remains of Messapicetus, which include other occurrences from Tortonian shelf deposits of southeastern Italy, southern Peru, and Maryland (eastern USA). Early branching beaked whales (including basal members of the so-called "Messapicetus clade") likely dispersed via the Central American Seaway, which allowed a direct communication between the Pacific and Atlantic oceans (including the Mediterranean cul-de-sac) throughout the Miocene.
