Karatavitidae

Karatavitidae is a science 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 Karatavitidae rather than just read about it. In short: Karatavitidae is an extinct family of sawflies, known from the Jurassic period, they are the only members of the superfamily Karatavitoidea. While once proposed to be grouped with the Orussoidea in the infraorder Orussomorpha, they are now considered to be the closest relatives of clade containing Orussoidea and Apocrita.

Key takeaways

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

Reference excerpt

Karatavitidae is an extinct family of sawflies, known from the Jurassic period, they are the only members of the superfamily Karatavitoidea. While once proposed to be grouped with the Orussoidea in the infraorder Orussomorpha, they are now considered to be the closest relatives of clade containing Orussoidea and Apocrita. There are about 7 genera in Karatavitidae.

Genera These seven genera belong to the family Karatavitidae:

† Grimmaratavites Rasnitsyn, Ansorge & Zhang, 2006 Green Series, Germany, Early Jurassic (Toarcian) † Karatavites Rasnitsyn, 1963 Karabastau Formation Kazakhstan, Middle-Late Jurassic (Callovian/Oxfordian), Daohugou, China, Callovian † Postxiphydria Rasnitsyn & Zhang, 2010 Karabastau Formation Kazakhstan, Middle-Late Jurassic (Callovian/Oxfordian) † Postxiphydroides Rasnitsyn & Zhang, 2010 Daohugou, China, Callovian † Praeparyssites Rasnitsyn, Ansorge & Zhang, 2006 Daohugou, China, Callovian † Praeratavites Rasnitsyn, Ansorge & Zhang, 2006 Daohugou, China, Callovian † Praeratavitoides Rasnitsyn & Zhang, 2010 Daohugou, China, Callovian

Worked examples

Example 1 — a first encounter with Karatavitidae

Start with the simplest possible case. Write down what Karatavitidae claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Karatavitidae 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 Karatavitidae 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 Karatavitidae

In research: Karatavitidae appears in science 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 Karatavitidae 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: Karatavitidae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Prehistoric insect families, Prehistoric insect stubs, Sawflies, so understanding it makes those chapters shorter.
In everyday life: Look for Karatavitidae 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 Karatavitidae in simple terms?

Why does Karatavitidae matter?

Because it connects several science 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 Karatavitidae?

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.
