Sinognathus is an extinct genus of gomphodont cynodonts from the Middle Triassic Ermaying Formation of China. Its type and only species is Sinognathus gracilis, which was named in 1959 by the Chinese palaeontologist C. C. Young.

Sinognathus
Sinognathus 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 Sinognathus rather than just read about it. In short: Sinognathus is an extinct genus of gomphodont cynodonts from the Middle Triassic Ermaying Formation of China. Its type and only species is Sinognathus gracilis, which was named in 1959 by the Chinese palaeontologist C.
Key takeaways
- Sinognathus belongs to science; place it in that map before memorising details.
- Learn the definition first, then one example that makes the definition concrete.
- Connect Sinognathus to a quantity you can measure, compute or draw — that is where exam questions come from.
- Reproduce the core statement of Sinognathus from memory before moving on to harder problems.
Reference excerpt
Worked examples
Example 1 — a first encounter with Sinognathus
Start with the simplest possible case. Write down what Sinognathus 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 Sinognathus 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 Sinognathus 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 Sinognathus
- In research
- Sinognathus 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 Sinognathus 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
- Sinognathus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anisian life, Cynognathia, Fossil taxa described in 1959, so understanding it makes those chapters shorter.
- In everyday life
- Look for Sinognathus 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 Sinognathus in simple terms?
Sinognathus is an extinct genus of gomphodont cynodonts from the Middle Triassic Ermaying Formation of China. Its type and only species is Sinognathus gracilis, which was named in 1959 by the Chinese palaeontologist C.
Why does Sinognathus 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 Sinognathus?
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 Sinognathus.
