Jamninkaornis

Jamninkaornis 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 Jamninkaornis rather than just read about it. In short: Jamninkaornis (lit. 'Jamninka bird') is an extinct genus of passerine bird in the suborder Tyranni (suboscines), known from the late Oligocene (Chattian age, 26 million years ago) of Poland. The genus contains a single species, Jamninkaornis kencampbelli, known from a single coracoid and humerus (pectoral and forelimb bones).

Key takeaways

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

Reference excerpt

Jamninkaornis (lit. 'Jamninka bird') is an extinct genus of passerine bird in the suborder Tyranni (suboscines), known from the late Oligocene (Chattian age, 26 million years ago) of Poland. The genus contains a single species, Jamninkaornis kencampbelli, known from a single coracoid and humerus (pectoral and forelimb bones).

Discovery and naming

The Jamninkaornis fossil material was discovered in rock outcrops near the former village site of Jamna Dolna in Podkarpackie Voivodeship (Subcarpathian province), southeast Poland. The specimen is housed at the Institute of Systematics and Evolution of Animals in Kraków, where it is permanently accessioned as specimen MSMD Av JAM2_1a+b. It consists of a right coracoid (pectoral girdle bone) and humerus (upper forelimb bone), preserved on two separate slabs of rock. In 2026, Zbigniew M. Bochenski and colleagues described Jamninkaornis kencampbelli as a new genus and species of passerine bird based on these fossil remains, establishing MSMD Av JAM2_1a+b as the holotype specimen. The generic name, Jamninkaornis, combines a reference to Jamninka, a stream and valley close to the type locality, with the Greek word ὄρνῑς (órnīs), meaning 'bird'. The specific name, kencampbelli, honors the American paleornithologist Kenneth E. Campbell Jr., and his research on fossil birds.

Worked examples

Example 1 — a first encounter with Jamninkaornis

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

In research: Jamninkaornis 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 Jamninkaornis 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: Jamninkaornis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chattian genera, Fossil taxa described in 2026, Fossils of Poland, so understanding it makes those chapters shorter.
In everyday life: Look for Jamninkaornis 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.
