DOI: 10.1080/02724634.2017.1366916
Abstract: ABSTRACT Odontocetes first appear in the fossil record during the early Oligocene and soon after show a near-worldwide distribution. However, little is still known of their early diversity, especially in the North Pacific Region. A… read more here.

DOI: 10.4202/app.00287.2016
Abstract: “Halitherium” bellunense is exclusively known from a single individual from upper Oligocene glauconitic sandstone near Belluno, northern Italy. According to a review of its morphological basis, which consists of associated cranial elements, some vertebrae and… read more here.
