Villarroelia

Villarroelia 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 Villarroelia rather than just read about it. In short: Villarroelia is an extinct genus of proterotheriid from the Middle Miocene of Colombia. Etymology The genus name, Villarroelia refers to the paleontologist Carlos Villarroel, for his contributions to the understanding of prehistoric South American mammals, while the specific name, V. toyotoi refers to the indigenous chief Toyotó, whose tribe was present in the area of the Villavieja River, in the present-day Huila D…

Key takeaways

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

Reference excerpt

Villarroelia is an extinct genus of proterotheriid from the Middle Miocene of Colombia.

Etymology The genus name, Villarroelia refers to the paleontologist Carlos Villarroel, for his contributions to the understanding of prehistoric South American mammals, while the specific name, V. toyotoi refers to the indigenous chief Toyotó, whose tribe was present in the area of the Villavieja River, in the present-day Huila Department in Colombia, where its fossils were discovered in sediments corresponding to the La Victoria Formation, belonging to the Honda Group of the Middle Miocene.

Description This animal is known from the holotype specimen IGM 250965, a partial skull lacking the anterior rostrum, although it retains the roots of the upper first premolar (P1), and some additional remains, including another skull, UCMP 39970, several molar teeth, fragments of the mandible, two cervical vertebrae, the right scapula, a distal end of the radius, the proximal end of the right femur, the left tibia, the calcaneus and several phalanges of the fingers. Its remains indicate that it was a running herbivore similar in shape and size to the southern genera Proterotherium and Anisolophus, although it had a greater degree of molarization of its premolar teeth, especially P3 and P4. Given that its remains show a mixture of primitive and advanced features it is difficult to say whether these resemblances correspond to their actual phylogenetics, awaiting more comprehensive analyses of the family Proterotheriidae.

Worked examples

Example 1 — a first encounter with Villarroelia

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

In research: Villarroelia 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 Villarroelia 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: Villarroelia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 1997, Fossils of Colombia, Honda Group, Colombia, so understanding it makes those chapters shorter.
In everyday life: Look for Villarroelia 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.
