Guemesia

Guemesia 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 Guemesia rather than just read about it. In short: Guemesia (named after Martín Miguel de Güemes, whose death bicentenary was in 2021) is a genus of abelisaurid dinosaur from the Late Cretaceous Los Blanquitos Formation of Salta Province, Argentina. The type and only species is Guemesia ochoai, known from a nearly complete braincase.

Key takeaways

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

Reference excerpt

Guemesia (named after Martín Miguel de Güemes, whose death bicentenary was in 2021) is a genus of abelisaurid dinosaur from the Late Cretaceous Los Blanquitos Formation of Salta Province, Argentina. The type and only species is Guemesia ochoai, known from a nearly complete braincase. It is one of the smallest abelisaurids currently known.

Discovery The holotype of Guemesia, IBIGEO-P 103, is a small, nearly complete braincase. It was found in the Los Blanquitos Formation, in the Amblayo Valley of Salta Province, Argentina. The specimen was described in 2022 by Agnolín et al. as belonging to a new genus and species of abelisaurid dinosaur, and the first dinosaur of its kind known from the area.

Classification Agnolín et al. place Guemesia as a derived abelisaurid within the clade Brachyrostra.

Paleoecology Guemesia is known from the Los Blanquitos Formation. The controversial tetanuran theropod Unquillosaurus is also known from this formation, as well as fossils of what may belong to a species of Titanosaurus.

Worked examples

Example 1 — a first encounter with Guemesia

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

In research
Guemesia 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 Guemesia 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
Guemesia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Abelisauridae, Dinosaur genera, Dinosaurs of Argentina, so understanding it makes those chapters shorter.
In everyday life
Look for Guemesia 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 Guemesia in simple terms?

Guemesia (named after Martín Miguel de Güemes, whose death bicentenary was in 2021) is a genus of abelisaurid dinosaur from the Late Cretaceous Los Blanquitos Formation of Salta Province, Argentina. The type and only species is Guemesia ochoai, known from a nearly complete braincase.

Why does Guemesia 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 Guemesia?

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 Guemesia.
