I am Roberta Martino and I work on European hippopotamoids. Through state of the art, 3D data acquisition and Geometric Morphometrics (GM) coupled with advanced R statistical proxies I will update Anthracotheriidae-Hippopotamidae systematics while identifying the evolutionary trends and the morphological variability followed by these hippopotamoids.
The revision of the giraffid material stored at the Museu Geológico (Lisbon, Portugal) using current analytical tools and methods leads us to the first identification in Portugal of a member of the Samotheriinae-Sivatheriinae clade. The material consists of a metacarpal from Casais da Formiga, Azambuja (MG 5733, later Middle Miocene, MN 7: 13-12.5...
The genus Hippopotamus dispersed from Africa to Europe during the Pleistocene and the taxon is testified from different Italian localities. Despite the large number of available specimens, Hippopotamus is mainly documented by fragmentary remains and detailed stratigraphic and/or geographic data are often absent or uncertain. In Italy, hippopotamuse...
The first dispersal of Hippopotamidae out of Africa is recorded around 6 Ma, but this event is documented only in a few European localities. Among them, the uppermost Miocene deposits of Gravitelli in Sicily yielded particularly abundant hippopotamid remains. These specimens, published at the beginning of the 20th century, went lost during the 1908...
Hippopotamidae are a group of large-sized mammals of interest for testing evolutionary traits in time and space. Variation in skull shape within Hippopotamidae is here investigated by means of shape analysis (Ge-ometric Morphometrics) and modern statistical approaches. Two-dimensional shape analysis is applied to dorsal and lateral views of extant...
Variations in body-size of Bos primigenius during the Pleistocene and Holocene were reported by several authors. According to them the auroch was generally charaterized by a relative increase in size during the Middle Pleistocene and a decrease in size during the late Late Pleistocene and in particular during the Holocene. In this research several...
The present research examines Late Pleistocene small mammals from the Mora Cavorso Cave (Latium, central Italy), a multi-tunnel karst cave, located at 715 m above sea level, on the eastern slopes of the Simbruini Mountains, c. 150 m above the upper Aniene River valley. The layer studied (L. 5) comprises a silty, pale reddish-brown palaeosoil, with...
