Margaritiflabellum

Margaritiflabellum is a science 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 Margaritiflabellum rather than just read about it. In short: Margaritiflabellum is an extinct enigmatic organism from late Ediacaran of Russia. It resembles an unfolded fan, and is also a monotypic genus, containing only Margaritiflabellum anatolii.

Key takeaways

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

Reference excerpt

Margaritiflabellum is an extinct enigmatic organism from late Ediacaran of Russia. It resembles an unfolded fan, and is also a monotypic genus, containing only Margaritiflabellum anatolii.

Discovery The first fossils of Margaritiflabellum were collected from the Kimberella Lens site of the Zimnegorsk locality in the Mezen Formation, White Sea, Arkhangelsk Region, Russia in 1994. It was formally described and named in 2014.

Etymology The generic name Margaritiflabellum derives from both the fictional character name "Margarita" and the Greek word "margarita", to mean pearl; and the Latin word flabellum, to mean fan, in reference to the shape and impressions of the organism. The specific name anatolii is in honour of Anatoly Fedorovich Stankovsky, a well known Russian geologist who had studied the White Sea area extensively, and in honour of him wishing to name an organism from the area after his favourite character from the book of "The Master and Margarita", although he passed the shortly before the organism was named in 2014. As such, Ivanstov fulfilled this wish.

Description Margaritiflabellum anatolii is a unfolded fan-shaped organism, ranging from 6–57 mm (0.2–2.2 in) in length and 7.3–63 mm (0.3–2.5 in) in width, and is of shallow negative relief preservation, meaning it is an impression on the rocks surface. The body itself contains numerous pits and impressions, with smaller ones being evenly distributed across the body, whilst larger ones are sporadically distributed. These pits are not visible in the smallest specimens. Surrounding the outer margin of the body is a distinct ribbon-like structure, which is sometimes smooth or folded in appearance, and are devoid of the pits seen in the main body.

Worked examples

Example 1 — a first encounter with Margaritiflabellum

Start with the simplest possible case. Write down what Margaritiflabellum claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Margaritiflabellum 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 Margaritiflabellum 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 Margaritiflabellum

In research: Margaritiflabellum appears in science 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 Margaritiflabellum 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: Margaritiflabellum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ediacaran life, Fossil taxa described in 2014, Incertae sedis, so understanding it makes those chapters shorter.
In everyday life: Look for Margaritiflabellum 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.
