Thililua

Thililua 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 Thililua rather than just read about it. In short: Thililua is a genus of polycotylid plesiosaur, containing one species, T. longicollis. Discovery The name Thililua is derived from that of an ancient aquatic god from local Berber mythology; longicollis refers to the animal's long neck.

Key takeaways

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

Reference excerpt

Thililua is a genus of polycotylid plesiosaur, containing one species, T. longicollis.

Discovery The name Thililua is derived from that of an ancient aquatic god from local Berber mythology; longicollis refers to the animal's long neck. Thililua has been found in Late Cretaceous (early Turonian) rocks in the High Atlas mountains of Morocco in north Africa. Thililua is the first Polycotylid plesiosaur discovered in Africa, and also the first discovered that lived at a subtropical latitude. In 2010, Thililua was transferred to Leptocleididae as a sister taxon to Nichollssaura.

Description

The type specimen of T. longicollis, which was described in 2003, consists of an almost complete skull and lower jaw, articulated with 37 vertebrae. Of these vertebrae, 30 were cervical (neck) vertebrae, which is an unusually high number compared to other Polycotylids, such as Dolichorhynchops, which had only 19 neck vertebrae, and Polycotylus, which had 26. It is believed to be an adult specimen, since some of the cranial sutures are very difficult to distinguish. Using comparisons with the head and neck length to body length ratio of a related genus, Dolichorhynchops, the estimated total length of Thililua was 5.5 to 6 metres.

Worked examples

Example 1 — a first encounter with Thililua

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

In research: Thililua 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 Thililua 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: Thililua is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 2003, Fossils of Morocco, Late Cretaceous plesiosaurs, so understanding it makes those chapters shorter.
In everyday life: Look for Thililua 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 Thililua in simple terms?

Thililua is a genus of polycotylid plesiosaur, containing one species, T. longicollis. Discovery The name Thililua is derived from that of an ancient aquatic god from local Berber mythology; longicollis refers to the animal's long neck.

Why does Thililua 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 Thililua?

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.
