Idicia

Idicia 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 Idicia rather than just read about it. In short: Idicia is an extinct genus of Palaeogene rodents belonging to the family Theridomyidae. The genus and its sole species Idicia vidalenci were both named by Monique Vianey-Liaud et al. in 2024 based on some holotype dentition from the French locality of Lavergne, dating to the middle Eocene.

Key takeaways

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

Reference excerpt

Idicia is an extinct genus of Palaeogene rodents belonging to the family Theridomyidae. The genus and its sole species Idicia vidalenci were both named by Monique Vianey-Liaud et al. in 2024 based on some holotype dentition from the French locality of Lavergne, dating to the middle Eocene. It was named in honor of Dominique Vidalenc, who discovered the holotype material. It is diagnosed as being a medium-sized and brachyodont (low-crowned) theridomyid with various specific morphologies of its cuspids. A wide range of other faunas were recovered form Lavergne along with Idicia such as the herpetotheriid Peratherium, nyctithere Saturninia, omomyid Necrolemur, carnivoraforme Quercygale, tapirulid Tapirulus, and the palaeothere Palaeotherium.

Worked examples

Example 1 — a first encounter with Idicia

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

In research: Idicia 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 Idicia 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: Idicia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Eocene rodents, Fossil taxa described in 2024, Fossils of France, so understanding it makes those chapters shorter.
In everyday life: Look for Idicia 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 Idicia in simple terms?

Why does Idicia 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 Idicia?

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.
