Reference excerpt

The sandstone false antechinus (Pseudantechinus bilarni), also known as the sandstone pseudantechinus, the sandstone antechinus, the sandstone dibbler, Harney's antechinus and the Northern dibbler, is a species of small carnivorous marsupial, which has a patchy distribution in Australia's Northern Territory.

Taxonomy The sandstone false antechinus was discovered in 1948 when it was collected on the American-Australian expedition to Arnhem Land. It was described in 1954, when it was given the species name bilarni, which reflects the Aboriginal pronunciation of Bill Harney, an Australian writer and naturalist who accompanied the expedition. The species has at times been assigned to the genus Antechinus, and was long believed to be a member of the genus Parantechinus. The latter genus currently contains a single species, traditionally known as the dibbler (Parantechinus apicalis) in Southwest Australia, from which this species gained a common name of Northern dibbler. Only recently the species has been moved to Pseudantechinus, where it is one of six species.

Description It is an insectivorous species that, like many other dasyurids, so exhausts itself in the breeding season that most of the males die, although unlike some other species, about 25% of both sexes survive to a second year. The sandstone false antechinus is partly diurnal and differs from the other members of its genus in its very long, narrow muzzle and its more greyish colour. The breeding season is May–July.

Habitat The sandstone false antechinus is found in rocky areas around the Top End and the Gulf of Carpentaria in the Northern Territory. It also inhabits coastal rock platforms on Marchinbar Island.

Worked examples

Example 1 — a first encounter with Sandstone false antechinus

Start with the simplest possible case. Write down what Sandstone false antechinus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sandstone false antechinus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sandstone false antechinus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sandstone false antechinus

In research: Sandstone false antechinus appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sandstone false antechinus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sandstone false antechinus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dasyuromorphs, IUCN Red List least concern species, Mammals described in 1954, so understanding it makes those chapters shorter.
In everyday life: Look for Sandstone false antechinus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
