Wannanosaurus

Wannanosaurus 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 Wannanosaurus rather than just read about it. In short: Wannanosaurus (meaning "Wannan lizard", named after the location where it was discovered) is a genus of basal pachycephalosaurian dinosaur from the Maastrichtian-aged (Upper Cretaceous) Xiaoyan Formation, about 70 million years ago, in what is now Anhui, China. The type species Wannanosaurus yansiensis was described by Hou Lian-Hai in 1977.

Key takeaways

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

Reference excerpt

Wannanosaurus (meaning "Wannan lizard", named after the location where it was discovered) is a genus of basal pachycephalosaurian dinosaur from the Maastrichtian-aged (Upper Cretaceous) Xiaoyan Formation, about 70 million years ago, in what is now Anhui, China. The type species Wannanosaurus yansiensis was described by Hou Lian-Hai in 1977. It is known from a single partial skeleton, including a partial skull roof and lower jaw, a femur and tibia, part of a rib, and other fragments. Because it has a flat skull roof with large openings, it has been considered primitive among pachycephalosaurs. Sometimes it has been classified as a member of the now-deprecated family Homalocephalidae, now thought to be an unnatural assembly of pachycephalosaurs without domed skulls. Although its remains are from a very small individual, with a femur length of approximately 8 centimetres (3.1 in) and an estimated overall length of about 60 centimetres (2.0 ft), the fused bones in its skull suggest that it was an adult at death. Like other pachycephalosaurs, it was probably herbivorous or omnivorous, feeding close to the ground on a variety of plant matter, and possibly insects as well.

Worked examples

Example 1 — a first encounter with Wannanosaurus

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

In research: Wannanosaurus 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 Wannanosaurus 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: Wannanosaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dinosaur genera, Dinosaurs of China, Fossil taxa described in 1977, so understanding it makes those chapters shorter.
In everyday life: Look for Wannanosaurus 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.
