Guchengosuchus

Guchengosuchus 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 Guchengosuchus rather than just read about it. In short: Guchengosuchus is an extinct genus of erythrosuchid archosauriform from the Early Triassic of China. It is known from a single holotype skeleton called IVPP V 8808, described in 1991 from the lower Ermaying Formation in Shanxi.

Key takeaways

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

Reference excerpt

Guchengosuchus is an extinct genus of erythrosuchid archosauriform from the Early Triassic of China. It is known from a single holotype skeleton called IVPP V 8808, described in 1991 from the lower Ermaying Formation in Shanxi. The lower Ermaying Formation dates back to the Olenekian stage of the Early Triassic, making Guchengosuchus one of the earliest archosauriforms. IVPP V 8808 is a disarticulated skeleton including a partial skull, lower jaw, some vertebrae, a scapula, and forelimb bones. Like some other erythrosuchids, Guchengosuchus has a tall skull with a notch between the premaxilla and maxilla bones of the upper jaw. The ribs of Guchengosuchus each have three heads, a feature also seen in the Russian erythrosuchid Vjushkovia. When it was first described, Guchengosuchus was placed in the suborder Proterosuchia, a group that included the families Erythrosuchidae, Proterosuchidae, and Proterochampsidae and was thought to be closely related to a primitive group of reptiles called Eosuchia. Proterosuchia is now considered a paraphyletic assemblage of basal archosauriforms representing a series of successive branches of stem group archosaurs.

Worked examples

Example 1 — a first encounter with Guchengosuchus

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

In research: Guchengosuchus 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 Guchengosuchus 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: Guchengosuchus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Early Triassic reptiles of Asia, Erythrosuchidae, Fossil taxa described in 1991, so understanding it makes those chapters shorter.
In everyday life: Look for Guchengosuchus 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.
