Comparative Anatomy, Phylogeny, and Systematics of the Miocene Giraffid Decennatherium pachecoi Crusafont, 1952 (Mammalia, Ruminantia, Pecora): State of the Art

The systematics of Decennatherium are reassessed, including its potential relationship with the second Iberian giraffid, the early Turolian Birgerbohlinia Crusafont, 1952, by means of the first cladistic analysis of the Giraffidae that includes DecENNatherium together with the most relevant African and Eurasian taxa, both fossil and extant.

First comprehensive morphological analysis on the metapodials of Giraffidae

Giraffids are a group of relict pecoran ruminants with only two living taxa. During the Miocene, however, this group was much more diverse, with more than 20 different species showing a wide range of

A New Species of Prolibytherium (Ruminantia, Mammalia) from Pakistan, and the Functional Implications of an Atypical Atlanto-Occipital Morphology

The approximation of the occipital condyles to a convergent state in two giraffids (Giraffokeryx punjabiensis and Schansitherium tafeli), each of which possesses multiple pairs of ossicones, presumably necessitating a strengthened atlanto-occipital joint.

Dead ossicones, and other characters describing Palaeotraginae (Giraffidae; Mammalia) based on new material from Gansu, Central China

The morphological data used in ruminant phylogenetics is reviewed, and it is shown even many of the less obviously functional features are subject to homoplasy and variation, especially when fossil taxa are included.

Sequence Stratigraphy of the Lower Miocene Moghra Formation in the Qattara Depression, North Western Desert, Egypt

There is no doubt that today, perhaps more than ever before, humanity faces a myriad of complex and demanding challenges. These include natural resource depletion and environmental degradation, food

This study investigates the evolutionary history of two of the archipelagos' older vertebrate taxa, the endemic Galápagos marine and land iguana (genera Amblyrhynchus and Conolophus) and strengthens the hypothesis that extended speciation times in the GaláPagos are possible.

Hoplitomerycidae fam. nov. (Ruminantia, Mammalia) from Neogene fissure fillings in Gargano (Italy) Part 1: The cranial osteology of Hoplitomeryx gen. nov. and a discussion on the classification of pecoran families

It is concluded that the endemic Ruminantia from the Late Miocene island-fauna of Monte Gargano (Italy) originated from antlerless Cervidae, and the presence of horncores justifies the classification of the Gargano ruminants in a separate family: Hoplitomerycidae fam.

African Land Mammal Ages

ABSTRACT We define 17 African land mammal ages, or AFLMAs, covering the Cenozoic record of the Afro-arabian continent, the planet's second largest land mass. While fossiliferous deposits are absent
