The northernmost South American fossil record of Boa constrictor (Boidae,Boinae) from the Plio–Pleistocene of El Breal de Orocual (Venezuela)

Onary-Alves, S.Y., Hsiou, A.S. & Rincón, A.D., July 2016. The northernmost South American fossil record of Boa constrictor (Boidae, Boinae) from the Plio–Pleistocene of El Breal de Orocual (Venezuela). Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Boa constrictor is an extant boid widely distributed through the neotropical region, from the north of Central America to central Argentina. The fossil record of the species includes examples from several localities across the Americas that extend beyond the current distribution of the species. Here we report the first Plio–Pleistocene fossils of Boa from Monagas state, Venezuela. The material comes from El Breal de Orocual (Maturín municipality), which is an inactive tar seep deposit emplaced within the Mesa Formation. The specimens consist of two isolated anterior trunk vertebrae, an articulated sequence of six mid-trunk vertebrae and two posterior trunk vertebrae. The vertebrae are attributed to B. constrictor based on the following features: robust and high vertebrae; thick zygosphene with a notched or concave anterior edge; presence of a paracotylar, subcentral and lateral foramina; marked parasagittal ridges; epizygapophyseal process evident on the dorsal surface of the postzygapophyseal articular facets and high blade-like neural spine. The presence of B. constrictor in northern of Venezuela indicates a palaeoenvironment probably like savanna crossed by rivers with riparian forests, and suggests the predominance of a mesothermal climate with a moderate rainfall.

Dispossession 1990s style: Aborigines,islanders and the policy making process of the Goss labor government

Aboriginal and Islander people in Queensland remain unempowered in the policy making process of government. This is achieved by downgrading and under‐resourcing the relevant portfolio, by co‐locating it with welfare, by giving other departments statutory rights in decision making on indigenous issues which are not reciprocal, by relocating key indigenous policy areas into otherwise antagonistic departments, by ghettoising the issues in Cabinet and by failing to elucidate clear policy guidelines on indigenous issues. The Goss government has also ensured that indigenous people remain unempowered outside of government by failing to legislate for regional land councils, Aboriginal majority on national parks boards of management and an Aboriginal‐controlled statutory acquisitions fund and by retaining excessive discretionary power in the administration of the 1991 Land Acts.
