Zhao Xijin

Zhao Xijin 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 Zhao Xijin rather than just read about it. In short: Zhao Xijin (赵喜进; born c. 1935 died July 21, 2012) was a Chinese paleontologist notable for having named numerous dinosaurs. He was a professor at Beijing's Institute of Vertebrate Paleontology and Paleoanthropology.

Key takeaways

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

Reference excerpt

Zhao Xijin (赵喜进; born c. 1935 died July 21, 2012) was a Chinese paleontologist notable for having named numerous dinosaurs. He was a professor at Beijing's Institute of Vertebrate Paleontology and Paleoanthropology.

Biography Zhao Xijin was born c.1935 in China.

Career Paul Sereno and Zhao went on a dinosaur fossil hunt in 2005 to Tibet to look for a site that Zhao had found 27 years prior. Before this hunt, in 2001, they had been engaged in a dig in the Gobi Desert. This involved a rock quarry that led them to finding 25 skeletons of the species Sinornithomimus dongi. In 2008, Zhao was involved in and in charge of a dig in Zhucheng that consisted of digging out a "980 ft-long pit". The site has unearthed more than 7,600 fossils through Xijin's work. It is believed to be the largest such site in the world. The majority of the fossils found appeared to be from the Late Cretaceous period. He died in 2012 at the age of 77.

Worked examples

Example 1 — a first encounter with Zhao Xijin

Start with the simplest possible case. Write down what Zhao Xijin 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 Zhao Xijin 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 Zhao Xijin 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 Zhao Xijin

In research: Zhao Xijin 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 Zhao Xijin 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: Zhao Xijin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930s births, 2012 deaths, Biologists from Shandong, so understanding it makes those chapters shorter.
In everyday life: Look for Zhao Xijin 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.
