Matanas

Matanas is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Matanas rather than just read about it. In short: Matanas enrighti is an extinct duck from the Miocene of New Zealand. It was described from fossil material (a left humerus) collected from a Saint Bathans Fauna site near Mata Creek, in the lower Bannockburn Formation of the Manuherikia Group, in the Manuherikia River valley in the Central Otago region of the South Island.

Key takeaways

Matanas belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Matanas to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Matanas from memory before moving on to harder problems.

Reference excerpt

Matanas enrighti is an extinct duck from the Miocene of New Zealand. It was described from fossil material (a left humerus) collected from a Saint Bathans Fauna site near Mata Creek, in the lower Bannockburn Formation of the Manuherikia Group, in the Manuherikia River valley in the Central Otago region of the South Island.

Name The genus name is a combination of the name of Mata Creek with anas (“duck”). The specific epithet honours Jack Enright, owner of the station on which the type material was collected.

Worked examples

Example 1 — a first encounter with Matanas

Start with the simplest possible case. Write down what Matanas 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 Matanas 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 Matanas 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 Matanas

In research: Matanas 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 Matanas 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: Matanas is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anatinae, Anseriformes stubs, Birds described in 2007, so understanding it makes those chapters shorter.
In everyday life: Look for Matanas 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.

Frequently asked questions

What is Matanas in simple terms?

Why does Matanas matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Matanas?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
