Osteochilus fossilis

Osteochilus fossilis is a science 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 Osteochilus fossilis rather than just read about it. In short: 'Osteochilus' fossilis is a genus of cypriniforms (presumably a Labeoninae) that lived in Sangkarewang Formation during the Eocene epoch. It is placed in genus Osteochilus tentatively based on the placement and ray number of the fins along taking account of its body proportion.

Key takeaways

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

Reference excerpt

'Osteochilus' fossilis is a genus of cypriniforms (presumably a Labeoninae) that lived in Sangkarewang Formation during the Eocene epoch. It is placed in genus Osteochilus tentatively based on the placement and ray number of the fins along taking account of its body proportion. There are only one specimen that was found but its current whereabout is unknown. Based on the describer (Sanders, 1934), O. fossilis have a relatively big head (around 29%) with a very deep body profile. The rear part was not preserved completely since it is missing the caudal peduncle and fins.

Worked examples

Example 1 — a first encounter with Osteochilus fossilis

Start with the simplest possible case. Write down what Osteochilus fossilis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Osteochilus fossilis 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 Osteochilus fossilis 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 Osteochilus fossilis

In research: Osteochilus fossilis appears in science 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 Osteochilus fossilis 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: Osteochilus fossilis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossils of Indonesia, Labeoninae, so understanding it makes those chapters shorter.
In everyday life: Look for Osteochilus fossilis 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.
