The Darwin Region languages are a small family of poorly attested Australian Aboriginal languages of northern Australia proposed by linguist Mark Harvey. It unites the pair of Limilngan languages with two language isolates:

In 1991, there were only two speakers of Tandia in the world, who they both lived just south of the Wohsimi River on the Wandamen Peninsula, Irian Jaya Province, Indonesia. It was confirmed to be a living language in 2009, but by 2024, it was found to have gone extinct by a linguistic survey team.

The language continues in communities in Waipia in Seram, where the islanders were resettled, along with those also from Nila and Teun. Here, the older generation retained the island language as a strong form of identity. It was found to be extinct in 2024.

Sahonachelyidae is an extinct family of pelomedusoid turtles from the Late Cretaceous (Maastrichtian) Maevarano Formation of Madagascar. The clade was recognized in 2021 by Joyce et al., and contains two genera: Sahonachelys and Sokatra. The clade is characterized by the presence of a reduced contribution of the maxilla to the floor of the orbit, and, the presence of a distinct posterior process of the maxilla. The clade went extinct at the end of the Cretaceous period during the K-Pg extinction event.
