Zhejiangosaurus

Zhejiangosaurus 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 Zhejiangosaurus rather than just read about it. In short: Zhejiangosaurus (meaning "Zhejiang lizard") is an extinct genus of ankylosaurian dinosaur from the Upper Cretaceous (Cenomanian stage) of Zhejiang, eastern China. It was first named by a group of Chinese authors Lü Junchang, Jin Xingsheng, Sheng Yiming and Li Yihong in 2007 and the type species is Zhejiangosaurus lishuiensis ("from Lishui", where the fossil was found).

Key takeaways

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

Reference excerpt

Zhejiangosaurus (meaning "Zhejiang lizard") is an extinct genus of ankylosaurian dinosaur from the Upper Cretaceous (Cenomanian stage) of Zhejiang, eastern China. It was first named by a group of Chinese authors Lü Junchang, Jin Xingsheng, Sheng Yiming and Li Yihong in 2007 and the type species is Zhejiangosaurus lishuiensis ("from Lishui", where the fossil was found). It has no diagnostic features, and thus is a nomen dubium.

Description Zhejiangosaurus could grow up to 4.5 m (17 ft) in length and was 1.4 metric tons in weight.

Material Material for Zhejiangosaurus consists of the holotype, ZNHM M8718, a partial skeleton which has preserved a sacrum with eight vertebrae, a complete right ilium and partial left ilium, a complete right pubis, the proximal end of the right ischium, two complete hindlimbs, fourteen caudal vertebrae, and some unidentified bones. These remains come from Liancheng, in the Chinese administrative unit of Lishui on the province of Zhejiang and they were collected from the Cenomanian-age Chaochuan Formation.

Systematics On the species description, Lü et al. (2007) found Zhejiangosaurus to belong to the ankylosaurian family Nodosauridae. Zhejiangosaurus in a cladogram after Pond et al. (2023):

Worked examples

Example 1 — a first encounter with Zhejiangosaurus

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

In research: Zhejiangosaurus 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 Zhejiangosaurus 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: Zhejiangosaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cenomanian dinosaurs, Dinosaur genera, Dinosaurs of China, so understanding it makes those chapters shorter.
In everyday life: Look for Zhejiangosaurus 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 Zhejiangosaurus in simple terms?

Why does Zhejiangosaurus 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 Zhejiangosaurus?

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.
