Ikechosaurus

Ikechosaurus 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 Ikechosaurus rather than just read about it. In short: Ikechosaurus (meaning "Ikh Juu lizard", in reference to the discovery locality of type species) is an extinct genus of choristodere reptile which existed in China and Mongolia during the Early Cretaceous. It contains four species: I. sunailinae, I. magnus, I. gaoi, and I. pijiagouensis.

Key takeaways

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

Reference excerpt

Ikechosaurus (meaning "Ikh Juu lizard", in reference to the discovery locality of type species) is an extinct genus of choristodere reptile which existed in China and Mongolia during the Early Cretaceous. It contains four species: I. sunailinae, I. magnus, I. gaoi, and I. pijiagouensis. It belongs to the crocodilian-like clade Neochoristodera and was initially assigned to the Champsosauridae by palaeontologist Denise Sigogneau-Russell in 1981. Compared to other neochoristoderes, Ikechosaurus has a rather simple dentition, lacking the speciations seen in latter species. It also has parasphenoid palatal teeth, a feature not seen in any other choristodere.

Worked examples

Example 1 — a first encounter with Ikechosaurus

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

In research: Ikechosaurus 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 Ikechosaurus 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: Ikechosaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Choristodera, Cretaceous choristoderes, Cretaceous reptiles of Asia, so understanding it makes those chapters shorter.
In everyday life: Look for Ikechosaurus 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.
