I resti fossili, più o meno frammentari, sono preservati entro i sedimenti della Formazione a Colombacci che ricolmavano numerose fessure paleocarsiche caratterizzanti la sottostante F.ne Gessoso-solfifera, il tutto sigil- lato da peliti marine della F.ne Argille Azzurre; un assetto geologico di questo tipo ha permesso di vincolare cronologicamente la paleofauna alla parte terminale del Messiniano, circa 5,4 milioni di anni fa. L’associazione fossile del Monticino è rappresentata da 58 diverse specie di vertebrati ter- restri e cioè 19 taxa tra anfibi e rettili (ad esempio coccodrillo, varano, boa delle sabbie, ecc.) e 39 taxa di mammiferi (ad esempio scimmia, oritteropo, rinoceronte, ecc.): tra questi ultimi si segnala- no ben 5 specie nuove per la Scienza, quali lo ienide Plioviverrops faventinus, il canide Eucyon mon- ticinensis, il bovide Samotragus occidentalis nonché i roditori Stephanomys debruijni e Centralomys benericettii. L’analisi ecologica della paleofauna ha permesso di ipotizzare un antico ambiente con clima di tipo temperato-caldo o sub-tropicale. Parole chiave: Fossili, Vertebrati continentali, Formazione a Colombacci, Messiniano terminale, Italia. Abstract The Monticino gypsum quarry (now converted into a geo-park), located near the town of Brisighella (Ravenna, Northern Italy), at the Eastern margin of the Vena del Gesso romagnola, is one of the most important paleontological sites with continental vertebrates in the Late Miocene of Italy.

A review of the Pliocene Hipparion crassum Gervais Group and other finds (Mammalia, Equidae) † Ann FORSTEN Finnish Museum of Natural History, PB 17, FIN-00014 Helsinki (Finland) Forsten A. 2002. — Latest Hipparion Christol, 1832 in Europe. A review of the Pliocene Hipparion crassum Gervais Group and other finds (Mammalia, Equidae). Geodiversitas 24 (2) : 465-486. ABSTRACT The mainly late Miocene equid genus Hipparion Christol, 1832 still occurred in the early and middle Pliocene of Eurasia. Known European finds are here reviewed; most are referred to a “H. crassum Group”, chiefly because of their common dental morphology, but also on their limb bone proportions KEY WORDS when known. The group may comprise more than one species, as indicated Mammalia, by metapodial proportions, but new taxa are not formally described, because Equidae, of the paucity of the material mostly consisting of isolated teeth. Some other Hipparion crassum Group, Pliocene, finds from the same period, sometimes referred to H. crassum Gervais, 1859 Europe. but of uncertain relationship, are discussed. RÉSUMÉ Les derniers Hipparion Christol, 1832 en Europe. Examen du Groupe Hipparion crassum Gervais du Pliocène et autres découvertes (Mammalia, Equidae). Le genre Hipparion Christol, 1832, qui date principalement du Miocène supérieur, est encore présent dans le Pliocène de l’Eurasie. Les découvertes européennes connues sont examinées ici ; la plupart se réfèrent au « Groupe H. crassum », principalement en raison de leur morphologie dentaire, mais MOTS CLÉS aussi des proportions des os de leurs membres. Certaines autres découvertes Mammalia, de la même époque, parfois se référant à H. crassum Gervais, 1859 mais dont Equidae, les affinités sont incertaines, sont discutées.

  • Isotopic Dietary Reconstructions of Pliocene Herbivores at Laetoli: Implications for Early Hominin Paleoecology ⁎ John D
    Palaeogeography, Palaeoclimatology, Palaeoecology 243 (2007) 272–306 www.elsevier.com/locate/palaeo Isotopic dietary reconstructions of Pliocene herbivores at Laetoli: Implications for early hominin paleoecology ⁎ John D. Kingston a, , Terry Harrison b a Department of Anthropology, Emory University, 1557 Dickey Dr., Atlanta, GA 30322, United States b Center for the Study of Human Origins, Department of Anthropology, New York University, 25 Waverly Place, New York, NY 10003, United States Received 20 September 2005; received in revised form 1 August 2006; accepted 4 August 2006 Abstract Major morphological and behavioral innovations in early human evolution have traditionally been viewed as responses to conditions associated with increasing aridity and the development of extensive grassland-savanna biomes in Africa during the Plio- Pleistocene. Interpretations of paleoenvironments at the Pliocene locality of Laetoli in northern Tanzania have figured prominently in these discussions, primarily because early hominins recovered from Laetoli are generally inferred to be associated with grassland, savanna or open woodland habitats. As these reconstructions effectively extend the range of habitat preferences inferred for Pliocene hominins, and contrast with interpretations of predominantly woodland and forested ecosystems at other early hominin sites, it is worth reevaluating the paleoecology at Laetoli utilizing a new approach. Isotopic analyses were conducted on the teeth of twenty-one extinct mammalian herbivore species from the Laetolil Beds (∼4.3–3.5 Ma) and Upper Ndolanya Beds (∼2.7–2.6 Ma) to determine their diet, as well as to investigate aspects of plant physiognomy and climate. Enamel samples were obtained from multiple localities at different stratigraphic levels in order to develop a high-resolution spatio-temporal framework for identifying and characterizing dietary and ecological change and variability within the succession.

Khan and 3Abdul Ghaffar 1Zoology department, Quaid-e-Azam campus, Punjab University, Lahore, Punjab, Pakistan 2Zoology Department, GC University, Faisalabad, Punjab, Pakistan 3Department of Meteorology, COMSATS Institute of Information Technology (CIIT), Islamabad ABSTRACT Fossil site Dhok Bun Ameer Khatoon (32o 47' 26.4" N, 72° 55' 35.7" E) yielded a significant amount of mammalian assemblage including two families of even-toed fossil mammal (Giraffidae, and Bovidae) and one family of odd-toed (Rhinocerotidae) of the Late Miocene (Samiullah, 2011). This newly discovered site has well exposed Chinji and Nagri formation and has dated approximately 14.2-9.5 Ma. This age agrees with the divergence of different mammalian genera. Sedimentological evidence of the site supports that this is deposited in locustrine or fluvial environment, as Chinji formation is composed primarily of mud-stone while the Nagri formation is sand dominated. Palaeoenvironmental data indicates that Miocene climate of Pakistan was probably be monsoonal as there is now a days. Mostly the genera recovered from this site resemble with the overlying younger Dhok Pathan formation of the Siwaliks while the size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site to add additional information in the field of Palaeontology. A detailed study of fossils mammals found in Miocene rocks exposed at Dhok Bun Ameer Khatoon was carried out.

ABSTRACT - The Pliocene fossil record of hipparionine horses in the Indian Subcontinent is poorly known. Historically, only one species, “Hippotherium” antelopinum Falconer & Cautley, 1849, was described from the Upper Siwaliks. Here, we present the frst evidence of Eurygnathohippus Van Hoepen, 1930, a lineage hitherto only known from Africa, in the Upper Siwaliks during the late Pliocene. Morphologically, the South Asian Eurygnathohippus is most similar to Eurygnathohippus hasumense (Eisenmann, 1983) from Afar, Ethiopia, a species with a similar temporal range.

This locality has been recently calibrated at the Pliocene/Pleistocene boundary (2.6 ± 0.2 Ma) and therefore it is of interest for the first appearance of the genus Equus and last appearance of hipparionine horses. The Roca-Neyra equid sample, re- analyzed herein using morphological, morphometrical, and statistical analyses, has revealed the co-occurrence of Plesio- hipparion cf. ?P. rocinantis and Equus cf. E. livenzovensis. The analysis undertaken on several European, African, and Asian “Hipparion” sensu lato species from late Miocene to Early Pleistocene has revealed different remnant Hipparion lineages in the Plio-Pleistocene of Europe: Plesiohipparion, Proboscidippaion, and likely Cremohipparion.

Each group is distinct in its occlusal enamel pattern. These patterns have been compared qualitatively but rarely quantitatively. The processes controlling the evolution of these occlusal patterns have not been thoroughly investigated with respect to phylogeny, tooth position, and climate through geologic time. I investigated two methods of quantitative analysis, Occlusal Enamel Index for shape and fractal dimensionality for complexity.
