Tyarrpecinus
genus of mammals
Tyarrpecinus is an extinct genus of thylacinid that lived during the late Miocene in what is now the Northern Territory, Australia. It is known only from a partial skull bone that was reconstructed from numerous fragments. It was a small thylacinid and represents a late surviving relict. The genus is monotypic, containing only one species, Tyarrpecinus rothi.
History and naming
Tyarrpecinus was named and described in 2000 based on fossil material recovered from the late Miocene Alcoota Local Fauna of the Waite Formation, Northern Territory. The holotype and only known specimen, NTM P98211, is a left maxillary fragment reassembled from a concentration of small bone and tooth fragments. It is thought that it represents the contents of a crocodile coprolite as the fragments exhibit signs of chemical erosion and have a layer of calcite on them. Fossils of Tyarrpecinus, as well as those of many other animals from Alcoota, were found in a dense bone bed that accumulated after a mass mortality event. The exact cause has been a subject of debate, with earlier studies suggesting that waterhole-tethering was the cause. However, more recently, it is thought that a flood was instead responsible.
The public source identifies “Tyarrpecinus” as genus of mammals. This brief keeps that definition visible, then builds a research path around Tyarrpecinus, genus and mammals.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Tyarrpecinus”, the useful work is to connect “genus of mammals” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 4, 2025. The linked authority identifier is Q21447917. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
