Very low (Technical/Specialist)Academic/Technical (Palaeoanthropology, Evolutionary Biology)
Definition
Meaning
A species of extinct, large-toothed hominin from the genus Australopithecus.
An extinct species of robust australopithecine, characterized by strong chewing adaptations including massive jaws, large molars, and a sagittal crest, that lived in South Africa between approximately 2.0 and 1.5 million years ago. It is now often classified in the genus Paranthropus.
Linguistics
Semantic Notes
The term is a taxonomic binomial (genus + specific epithet). It names a specific fossil species, not a general concept. The genus name is capitalised, the specific epithet is not. Often referred to informally as 'robust australopithecine'. The classification is debated, with many scholars using Paranthropus robustus.

Examples
By CEFR Level
- Scientists have found many fossils of Australopithecus robustus.
- Australopithecus robustus, with its large teeth and strong jaw, likely ate tough plants.
- The cranial morphology of Australopithecus robustus, including its pronounced sagittal crest, indicates powerful mastication, suggesting a diet of mechanically challenging vegetation.

Mnemonic
Imagine a ROBUST, muscular ape-man from AUSTRALia (though it's from Africa), PITHing (removing) fruit with its strong teeth: Australo-PITH-ecus ROBUST-us.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating the Latin binomial directly. It is not 'Австралопитек робустусный'. The standard Russian term is 'Парантроп массивный' or 'Австралопитек массивный'.
- The word 'robustus' is Latin for 'robust, strong', referring to the skull and teeth, not overall body strength.
Common Mistakes
- Incorrect capitalisation: 'australopithecus Robustus' or 'Australopithecus Robustus'.
- Pronouncing 'robustus' as /roʊˈbʌst.uːs/ (with a 'uː' sound).
- Using it as a common noun, e.g., 'an Australopithecus robustus' instead of 'a specimen of Australopithecus robustus'.

FAQ
Frequently Asked Questions
No, it is considered an evolutionary side branch, or 'cousin' lineage, that went extinct and is not a direct ancestor of Homo sapiens.
Fossils have been found primarily in cave sites in South Africa, such as Swartkrans, Kromdraai, and Drimolen.
It is Latin for 'robust' or 'strong', referring to the heavily built skull, jaw, and teeth adapted for chewing.
They refer to the same fossil species. Some scientists place it in the genus Australopithecus, while others classify it in a separate genus, Paranthropus, due to its specialised features.
