Huangshanlong

Huangshanlong 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 Huangshanlong rather than just read about it. In short: Huangshanlong (meaning "Huangshan dragon") is a genus of mamenchisaurid dinosaurs native to the Anhui province of China. It contains a single species, Huangshanlong anhuiensis, which represents, along with Anhuilong and Wannanosaurus, one of the three dinosaurs found in Anhui province.

Key takeaways

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

Reference excerpt

Huangshanlong (meaning "Huangshan dragon") is a genus of mamenchisaurid dinosaurs native to the Anhui province of China. It contains a single species, Huangshanlong anhuiensis, which represents, along with Anhuilong and Wannanosaurus, one of the three dinosaurs found in Anhui province.

Discovery and description The only specimen consists of a partial forelimb discovered in 2002 during the construction of the Huihang Highway. It can be distinguished from other mamenchisaurids in having the following unique combination of features: such as transverse length of the proximal end of the humerus is 36% of the total length of the humerus, accessory processes are located near the middle of the cranial edge of the distal end of the humerus, length of the radius is 58% of that of the humerus, length of the ulna is two thirds of that of the humerus, craniomedial process on the proximal end of the ulna is longer than the craniolateral one, and ridges develop on the cranial, caudomedial, and caudolateral faces of the distal portion of the ulna.

Ren et al. (2018) recover Huangshanlong as sister to Anhuilong and Omeisaurus in a clade within Mamenchisauridae exclusive of other mamenchisaurids.

Worked examples

Example 1 — a first encounter with Huangshanlong

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

In research: Huangshanlong 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 Huangshanlong 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: Huangshanlong is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dinosaur genera, Dinosaurs of China, Fossil taxa described in 2014, so understanding it makes those chapters shorter.
In everyday life: Look for Huangshanlong 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.
