Proaulopora

Proaulopora 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 Proaulopora rather than just read about it. In short: Proaulopora is a Cambrian–Ordovician fossil genus of calcareous algae. It has been variously thought to belong to the green algae, red algae or cyanobacteria.

Key takeaways

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

Reference excerpt

Proaulopora is a Cambrian–Ordovician fossil genus of calcareous algae. It has been variously thought to belong to the green algae, red algae or cyanobacteria. It was originally established by the Russian paleontologist Aleksandr Grigoryevich Vologdin in 1937, for species known from the Lower Cambrian of the western Altai Mountains. In some older classifications of fossil algae genera, Proaulopora is placed in the family Proauloporaceae in order Proauloporales. In 2020, the genus was assigned to the cyanobacteria order Nostocales. Proaulopora resembles some species of the extant rivulariacean genus Dichothrix, and has also been compared with the genus Calothrix.

Species The genus contains the following species:

Proaulopora composita Korde, 1973 Proaulopora crassa Korde, 1973 Proaulopora extincta Korde, 1973 Proaulopora glabra Krasnopeeva, 1937 (Synonyms: Epiphyton (?) jacutii Maslov, 1937; Tubophyllum victori Krasnopeeva, 1955; Palaeonites jacutii Maslov, 1956; Vologdinella fragile Korde, 1957) Proaulopora longa Korde, 1973 Proaulopora microspora Korde, 1973 Proaulopora ordosia Liu, et al., 2020 Proaulopora pachydermatica Liu, Wu, Yang & Riding, 2016 Proaulopora rarissima Vologdin, 1937 (Synonyms: Proaulopora sajanica Korde, 1960; Proaulopora flexuosa Korde, 1973) Proaulopora recta Korde, 1973 As Vologdinella K.B. Korde, the following additional species are listed on AlgaeBase:

Vologdinella grandis Korde, 1973 Vologdinella pulchra Korde, 1973 It is unknown whether the above species have been transferred to Proaulopora or have become synonyms.

Worked examples

Example 1 — a first encounter with Proaulopora

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

In research: Proaulopora 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 Proaulopora 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: Proaulopora is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil algae, Nostocales, so understanding it makes those chapters shorter.
In everyday life: Look for Proaulopora 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 Proaulopora in simple terms?

Proaulopora is a Cambrian–Ordovician fossil genus of calcareous algae. It has been variously thought to belong to the green algae, red algae or cyanobacteria.

Why does Proaulopora matter?

Because it connects several science 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 Proaulopora?

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.
