Phaulactis cyathophylloides

Phaulactis cyathophylloides 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 Phaulactis cyathophylloides rather than just read about it. In short: Phaulactis cyathophylloides is an extinct species of rugose coral known from the silurian layers of Gotland, and Estonia. It is the type species of the genus Phaulactis and was described by Ryder in 1926.

Key takeaways

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

Reference excerpt

Phaulactis cyathophylloides is an extinct species of rugose coral known from the silurian layers of Gotland, and Estonia. It is the type species of the genus Phaulactis and was described by Ryder in 1926. It can grow to relatively large sizes.

Description The species can have two different shapes, either turbinate or cylindrical. It can grow to 60 mm in length and 20 mm in diameter. The calyx is very deep and the septal ridges are well marked. As all other Phaulactis species, it has large amount of septa.

Worked examples

Example 1 — a first encounter with Phaulactis cyathophylloides

Start with the simplest possible case. Write down what Phaulactis cyathophylloides 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 Phaulactis cyathophylloides 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 Phaulactis cyathophylloides 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 Phaulactis cyathophylloides

In research: Phaulactis cyathophylloides 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 Phaulactis cyathophylloides 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: Phaulactis cyathophylloides is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa of Gotland, Prehistoric invertebrate stubs, Stauriida, so understanding it makes those chapters shorter.
In everyday life: Look for Phaulactis cyathophylloides 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.
