New finds of unreworked fossils of Xiphiacetus cristatus (Eurhinodelphinidae) in the middle Tortonian Diest Formation in Belgium (9.54–8.8 Ma) allow for the documentation of the survival of a hyper-longirostrine dolphin into the early late Miocene. An extensive dataset of the rostral index (calculated as the ratio between rostral length and condylobasal length) of Neogene and extant odontocetes is compiled and presented here, which facilitates discussion of evolutionary trends of rostrum proportions during a time period spanning 23 million years. Of interest, the iterative survival into the late Miocene of a single different species of hyper-longirostrine dolphins in a number of paleogeographic regions (North Sea Basin, Atlantic Coastal Plain, and probably the southeastern Pacific) is noted, whereas hyper-longirostrine morphologies only seem to re-appear by the late Messinian in the Northeastern Pacific. A correlation between this pattern and a decrease in habitat size for coastal to estuarine dolphins linked to a major sea level drop is tentatively proposed; such a process may also have played a role in the ecological shift in several dolphin families to freshwater habitats.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Late Miocene survival of a hyper-longirostrine dolphin and the Neogene to recent evolution of rostrum proportions among odontocetes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Xiphiacetus cristatus; Eurhinodelphinidae; Tortonian; Hyper-longirostry; Extinction; North Sea","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-06-29","DateCreate":"2022-06-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000711280200001","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s10914-021-09573-6"},"refs":null,"anarec":{"AnaID":353102,"PubliDate":2022,"Pagination":"99-111","XtraPublOfAnaID":null,"ISBN":null,"Volume":"29","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":272471,"SerRR":"Journal of Mammalian Evolution.
