Pig-nosed turtle
species of reptile
The pig-nosed turtle (Carettochelys insculpta), also known as the Fly River turtle, pitted-shelled turtle, and the Warrajan, is a species of turtle which is native to northern Australia and southern New Guinea. It is the only living member of the genus Carettochelys and family Carettochelyidae, a family which also contains many fossil species with their closest relatives being the softshell turtles (family Trionychidae).
Taxonomy
C. insculpta is the only living member of the genus Carettochelys, the subfamily Carettochelyinae, and the family Carettochelyidae, with Carettochelyidae being one of two families in the Trionychia, alongside Trionychidae (softshell turtles). Carettochelyidae has an extensive fossil record extending into the Early Cretaceous, and was formerly widespread, with fossils having been found in Asia, North America, Europe, Africa and Australia. Some literature claims two subspecies, but a 2010 paper rejects this. A fossil species of the genus, Carettochelys niahensis is known from the Neogene of Borneo.

Why this record matters
“Pig-nosed turtle” is worth following because a concise public description often conceals a longer documentary argument. Here, Pig-nosed, turtle and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q457742. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010 and 2025.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
