Background The best European locality for complete Eocene mammal skeletons is Grube Messel, near Darmstadt, Germany. Although the site was surrounded by a para-tropical rain forest in Eocene, primates are remarkably rare there, and only eight fragmentary specimens were known until now. Messel has now yielded full primate skeleton. specimen an unusual history: it privately collected sold two parts, with lesser part previously known. second part, which just come to light, shows skeleton be...
Worn enamel surfaces of the cheek teeth in fossil and recent rhinoceroses are characterized by fine, parallel ridges aligned perpendicular to enamel-dentin interface. We show that these result from an unusual ultrastructure which a primitively horizontal layering prisms has become vertical. The new structure apparently appeared between early middle Eocene, at time when superfamilies perissodactyls were rapidly diverging. Similar modifications occurred certain parts tapiroids,...
Protocetidae are middle Eocene (49-37 Ma) archaeocete predators ancestral to later whales. They found in marine sedimentary rocks, but retain four legs and were not yet fully aquatic. Protocetids have been interpreted as amphibious, feeding the sea returning land rest.Two adult skeletons of a new 2.6 meter long protocetid, Maiacetus inuus, described from early Habib Rahi Formation Pakistan. M. inuus differs contemporary archaic whales having fused mandibular symphysis, distinctive astragalus...
Morphology and schmelzmuster of rootless cheek teeth 25 extant rodent genera were studied in relation to jaw movement. A differentiation between leading trailing edges is observed regularly enamel thickness schmelzmuster. Similarities antagonists are interpreted as ‘functional symmetries’. Differences the thickness, orientation cutting controlled by functional phylogenetic constraints. The heterogenous sample allows discrimination these two most obvious constraint leads almost regular...
Four different Hunter-Schreger Band (HSB) configurations were observed in the teeth of fossil and extant Perissodactyla.This variability exceeds that Artiodactyla or Proboscidea.The four HSB represent two evolutionary pathways.Transverse found many mammalian taxa outside Perissodactyla represents most primitive configuration.It occurs several perissodactyl families is retained Palaeotheriidae Equidae.Curved evolved from transverse Tapiridae, Helaletidae, Lophiodontidae, as well Ancylopoda...
Abstract Gondwanatherians are an enigmatic group of extinct non-therian mammals apparently restricted to some the western Gondwanan continents (Late Cretaceous-early Palaeocene South America, and Late Cretaceous Madagascar India). They developed rodent-like incisors earliest known hypsodont cheek-teeth among mammals. Recently, a small dentary fragment was recovered from middle Eocene beds on Antarctic Peninsula, preserving part incisor; both incisor enamel structure mandibular morphology...
Abstract. Die von Jánossy für Ungarn erarbeitete Gliederung der Kleinsäugerfaunen wird auf Grund in jüngster Zeit bearbeiteten die Verhältnisse Deutschland übertragen. Dabei ist es möglich, zwischen Cromer- und Eem-Interglazial vier Faunentypen auszugliedern, durch Vergesellschaftung verschiedener Arten gekennzeichnet sind. „Mimomys savini Fauna" vertritt das Cromer einen Teil des Elster (= Mindel) Glazials. „Arvicola Fauna, Typ 1" entspricht weitgehend dem Glazial. 2" umfaßt Holstein...
Many types of wear facets can be found in mammalian teeth. Some are related to the initial surface, others use cross-section enamel as main tool. In primary occlusal surfaces mark gradual wear, that a relatively late ontogeny. Facets teeth with secondary surfaces, however, represent specific arrangements crests and dentine. Such require some become fully functional. The tooth morphology guarantees such effective for long period time. Therefore they discriminated specialized facets. From...
