Jurahylobittacus

Jurahylobittacus 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 Jurahylobittacus rather than just read about it. In short: Jurahylobittacus is an extinct genus of hangingfly in the family Bittacidae and containing a single species Jurahylobittacus astictus. The species is known only from the Middle Jurassic Jiulongshan Formation, part of the Daohugou Beds, near the village of Daohugou in Ningcheng County, northeastern China.

Key takeaways

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

Reference excerpt

Jurahylobittacus is an extinct genus of hangingfly in the family Bittacidae and containing a single species Jurahylobittacus astictus. The species is known only from the Middle Jurassic Jiulongshan Formation, part of the Daohugou Beds, near the village of Daohugou in Ningcheng County, northeastern China.

History and classification Jurahylobittacus astictus is known only from one fossil, the holotype, specimen numbers "CNU-M-NN2007002-1" and "CNU-M-NN2007002-2" for the part and counterpart respectively. The specimen is composed of an almost complete specimen of unidentified sex and is preserved as a compression fossil in a sedimentary rock. The fossil was recovered from outcrops of the Jiulongshan Formation exposed in the Wuhua Township by Chung-Kun Shih. The type specimen is currently preserved in the Key Lab of Insect Evolution & Environmental Changes collections housed in the Capital Normal University, located in Beijing, China. Jurahylobittacus was first studied by Yan-Li Li, Dong Ren and ChungKun Shih of the Capital Normal University. Their 2008 type description of the genus and species was published online and then in print in the journal Zootaxa. The generic name was coined by Li, Ren and Shih from a combination of "Jura" a reference to the Jurassic; and the modern Bittacidae genus Hylobittacus to which Jurahylobittacus is related. The etymology of the specific epithet astictus is in reference to the lack of maculae present on any of the holotype specimens' wings. Jurahylobittacus astictus is one of six genera of fossil Bittacidae to be described from China. Along with Jurahylobittacus, Mongolbittacus and Formosibittacus are known from the Jiulongshan Formation, while Megabittacus and Sibirobittacus are from the Yixian Formation and Liaobittacus is from the Haifanggou Formation.

Description The holotype specimen is fully complete with only the apical sections of the legs obscured. The fore and hind-wings of Jurahylobittacus do not show any signs color pattering unlike the genus Formosibittacus which it lived alongside. Also unlike Formosibittacus the wings of J. astictus do not have any maculae. The fore-wings are 12.6 millimetres (0.50 in) long and the hind-wings are 10.3 millimetres (0.41 in) long. The hind and forewings are generally similar in overall vein structure to the extinct Sibirobittacus and also to the modern Hylobittacus but can be distinguished from both by the finer venation details. Overall the wings of Jurahylobittacus have a narrow base section widening to approximately 3 millimetres (0.12 in) along most of the length, while the body was 18 millimetres (0.71 in) in length.

Worked examples

Example 1 — a first encounter with Jurahylobittacus

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

In research: Jurahylobittacus 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 Jurahylobittacus 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: Jurahylobittacus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 2008, Hangingflies, Jurassic insects of Asia, so understanding it makes those chapters shorter.
In everyday life: Look for Jurahylobittacus 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.
