Largirostrornis

Largirostrornis 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 Largirostrornis rather than just read about it. In short: Largirostrornis is a genus of enantiornithean bird. One species has been named, Largirostornis sexdentoris.

Key takeaways

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

Reference excerpt

Largirostrornis is a genus of enantiornithean bird. One species has been named, Largirostornis sexdentoris. It lived during the Early Cretaceous and is known from fossils found in the Jiufotang Formation in Liaoning province, People's Republic of China. Some researchers believe this species to be a junior synonym of the similar Cathayornis yandica. Largirostrornis is known from one fossil, slab and counterslab, found in the Jiufotang Formation in Liaoning province, People's Republic of China. The Jiufotang Formation is dated to the Early Cretaceous period, late Aptian age, 120.3 ±0.7 million years ago. The holotype fossil is in the collection of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, China. It has been given catalog number IVPP 10531. L. sexdentornis had in 1997 a torso longer than all other known Enantiornithes. It is slightly larger than Cuspirostrisornis, with a skull about 32 millimeters long. The paired dentaries and premaxillae each hold six teeth. There are tall neural spines on the cervical and dorsal vertebrae.

Etymology The species was named and described by Hou Lianhai in 1997. The genus name comes from the Latin words largus, "large" and rostrum, "beak", and the specific name means "six-toothed" from Latin sex and dens.

Worked examples

Example 1 — a first encounter with Largirostrornis

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

In research: Largirostrornis 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 Largirostrornis 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: Largirostrornis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird genera, Early Cretaceous birds of Asia, Enantiornithes, so understanding it makes those chapters shorter.
In everyday life: Look for Largirostrornis 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.
