Quercylurus

Quercylurus 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 Quercylurus rather than just read about it. In short: Quercylurus is an extinct nimravid carnivora (or "false sabre-toothed cat") from the Early to Late Oligocene of France and Spain. Its fossils were found in Early Oligocene strata in Quercy.

Key takeaways

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

Reference excerpt

Quercylurus is an extinct nimravid carnivora (or "false sabre-toothed cat") from the Early to Late Oligocene of France and Spain. Its fossils were found in Early Oligocene strata in Quercy. It is known with only one species Quercylurus major. Q. major was one of the largest nimravids ever known, as its fossils suggest it was similar in size to the modern-day lion. Currently there is only one described species within this genus, the type species, Q. major. Q. major lived in the moist and humid forests of Oligocene Europe, alongside the much smaller, fellow nimravid Eofelis.

Taxonomy Quercylurus was named by Ginsburg (1979), and initially assigned to Felidae by Carroll in 1988. It would be placed as a member of Nimravidae, within the subfamily Nimravinae. Quercylurus was at one point classified as Nimravus intermedius major, and then classed within the Dinailurictis genus. More recent research typically places Quercylurus, Dinailurictis, and Eofelis as closely related, but distinct genera representing a European clade of nimravids. Quercylurus and Dinailurictis in particular share many similarities, with size being the chief distinguishing factor in some research.

Description Quercylurus is considered the largest Nimravinae known, with remains indicating individuals roughly comparable to modern lions with mass estimates around 200 kg (440 lb); only barbourofelin Barbourofelis fricki grew larger. Quercylurus somewhat resembled actual felines, with an elongated back and shortened snout, whilst having plantigrade limbs. The robust premolars suggests it may have included some bone in its diet.

Worked examples

Example 1 — a first encounter with Quercylurus

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

In research: Quercylurus 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 Quercylurus 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: Quercylurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossils of France, Monotypic prehistoric carnivoran genera, Nimravidae, so understanding it makes those chapters shorter.
In everyday life: Look for Quercylurus 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 Quercylurus in simple terms?

Quercylurus is an extinct nimravid carnivora (or "false sabre-toothed cat") from the Early to Late Oligocene of France and Spain. Its fossils were found in Early Oligocene strata in Quercy.

Why does Quercylurus 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 Quercylurus?

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.
