Guarinisuchus

Guarinisuchus 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 Guarinisuchus rather than just read about it. In short: Guarinisuchus is an extinct genus of marine crocodyliform from the Early Paleocene 62 million years ago in the Maria Farinha Formation, Brazil. The type species is G. munizi.

Key takeaways

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

Reference excerpt

Guarinisuchus is an extinct genus of marine crocodyliform from the Early Paleocene 62 million years ago in the Maria Farinha Formation, Brazil. The type species is G. munizi. It was a dominant predator in its environment, and probably reached a length of 3 metres (9.8 ft). Guarinisuchus appears to be closely related to marine crocodylomorphs found in Africa, which supports the hypothesis that the group originated in Africa and migrated to South America before spreading into the waters off the North American coast.

Worked examples

Example 1 — a first encounter with Guarinisuchus

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

In research: Guarinisuchus 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 Guarinisuchus 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: Guarinisuchus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dyrosauridae, Fossil taxa described in 2008, Fossils of Brazil, so understanding it makes those chapters shorter.
In everyday life: Look for Guarinisuchus 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 Guarinisuchus in simple terms?

Guarinisuchus is an extinct genus of marine crocodyliform from the Early Paleocene 62 million years ago in the Maria Farinha Formation, Brazil. The type species is G. munizi.

Why does Guarinisuchus 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 Guarinisuchus?

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.
