Marplesornis

Marplesornis 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 Marplesornis rather than just read about it. In short: Marplesornis novaezealandiae, also referred to as Harris's penguin, is a genus and species of extinct penguin from New Zealand. It was a relatively large penguin, about the same size as a king penguin.

Key takeaways

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

Reference excerpt

Marplesornis novaezealandiae, also referred to as Harris's penguin, is a genus and species of extinct penguin from New Zealand. It was a relatively large penguin, about the same size as a king penguin. The age of the only known specimen is uncertain, being often mentioned as Late Pliocene in age. However, due to the complex geology of the collection site, its actual age is somewhere between Early Miocene and Late Pliocene.

History The penguin was described by Brian Marples from fossil material (a fairly complete skeleton) collected by G. Harris in 1955 from Motunau Beach in the Canterbury region of the South Island. Marples placed it in Paleospheniscus, a genus known from Argentina. It was subsequently moved by George Gaylord Simpson to the new, monotypic genus Marplesornis, named to honour the original describer. The specific epithet is a Latinisation of "New Zealand". The common name recognises the discoverer of the type material.

Worked examples

Example 1 — a first encounter with Marplesornis

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

In research: Marplesornis 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 Marplesornis 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: Marplesornis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Birds described in 1960, Birds described in 1972, Extinct birds of New Zealand, so understanding it makes those chapters shorter.
In everyday life: Look for Marplesornis 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 Marplesornis in simple terms?

Why does Marplesornis 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 Marplesornis?

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.
