Allaeochelys libyca, a new carettochelyine turtle from the middle miocene (Langhian) of Libya

Fossil carettochelyine turtles are well known from the Paleogene of Europe (Allaeochelys), North America and Asia (Anosteira); however, the previously known Neogene fossil record is highly fragmentary and was therefore unsuitable for taxonomic analysis. In this work, we present a new carettochelyine taxon, Allaeochelys libyca, from the Middle Miocene (Langhian) of Gebel Zelten (Libya) based on an incomplete skull and disarticulated postcranial elements. The new taxon is diagnosed relative to the extant Carettochelys insculpta based on the placement of the foramen posterius canalis carotici interni close to the fenestra postotica, the horizontal orientation of the tubercula basioccipitalis, the substantial contribution of the opisthotic to the base of the tubercula basioccipitalis, the presence of a triangular pterygoid fossa, the arrangement of the mandibular condyles along a plane and the presence of an extremely well-developed fossa at the base of the processus mandibularis. A phylogenetic analysis of pancarettochelyids confirms the monophyly of Carettochelyidae and Carettochelyinae but resulted in a paraphyletic taxon, Allaeochelys. For the sake of nomenclatural stability, we provisionally retain the genus Allaeochelys as paraphyletic relative to the extant Carettochelys insculpta

A review of the fossil record of turtles of the clade Pan-Carettochelys

Turtles of the total clade Pan-Carettochelys have a relatively poor fossil record that extends from the Early Cretaceous. The clade is only found in Asia during the Cretaceous, but spreads to Europe and North America during the Eocene. Neogene finds are restricted to Europe, Africa and Australia, whereas the only surviving species, Carettochelys insculpta, lives in New Guinea and the Northern Territories of Australia. The ecology of fossil pan-carettochelyids appears similar to that of the extant C. insculpta, although more primitive representatives were likely less adapted to brackish water. Current phylogenies only recognize three internested clades: Pan- Carettochelys, Carettochelyidae and Carettochelyinae. A taxonomic review of the group concludes that of 25 named taxa, 13 are nomina valida, 7 are nomina invalida, 3 are nomina dubia, and 2 are nomina nuda

Individualism, Rights and Development

The Rights Based Approach (RBA) of development, suggesting duty-bearers should be held to account through Human Rights, has recently gained prominence. This study will evaluate the philosophical and societal underpinnings of this theory, developing an alternative method of development based on the criticisms of RBA. By using methods and theories from political philosophy this thesis will provide an original conception of the weakness of RBA’s as a theory. In addition to other societal concerns, this research will first and foremost reveal individualism to be the central weakness of RBA and hence will build a theory of development based on community building. The study will conclude that the social nature of the individual needs to be central to any method of development, which additionally needs to take into account the urban reality of the 21st century, without condoning violent upheaval. Furthermore, showing that rights are less useful in the field of development and that RBA has been instrumentalized to absolve northern countries of their historical responsibilities towards development, finally concluding that liberalism in general conflicts with a more communal lifestyle inherent to the Global South. These deductions will instigate the conceptualisation of the Big Table, a method of conciliatory development including all present stakeholders accompanied by neutral facilitators
