Guimarotodon

Guimarotodon 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 Guimarotodon rather than just read about it. In short: Guimarotodon is an extinct mammal of the Upper Jurassic. It was a relatively early member of the also extinct order of Multituberculata.

Key takeaways

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

Reference excerpt

Guimarotodon is an extinct mammal of the Upper Jurassic. It was a relatively early member of the also extinct order of Multituberculata. It made its living nibbling plants as great big, and small, dinosaurs roamed the world. (For the technically minded, suborder Plagiaulacida, family Paulchoffatiidae.) Guimarotodon ("Guimarota tooth") Hahn G, 1969. "Guimarotodon Hahn 1969 exhibits a more slender Corpus mandibulae than either Paulchoffatia or Meketibolodon. The most conspicuous character of this genus is the morphology of the P3-4 and the M1.". The Corpus mandibulae is the part of the jaw below the tooth row. P3-4 are upper premolars, whilst M1 is an upper molar tooth. "The incisor is relatively little curved and its root is of similar length as that of Meketibolodon and extends to underneath the posterior premolars." (Both quotations from Hahn & Hahn 2000, p. 105-106).

Guimarotodon leiriensis Guimarotodon leiriensis is found in Kimmeridgian (Upper Jurassic) of Guimarota, Portugal. Classification is based on three lower jaws. The species name refers to the local town of Leiria.

Worked examples

Example 1 — a first encounter with Guimarotodon

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

In research: Guimarotodon 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 Guimarotodon 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: Guimarotodon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 1969, Late Jurassic mammals of Europe, Mesozoic mammal stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Guimarotodon 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 Guimarotodon in simple terms?

Guimarotodon is an extinct mammal of the Upper Jurassic. It was a relatively early member of the also extinct order of Multituberculata.

Why does Guimarotodon 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 Guimarotodon?

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.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Guimarotodon.
