Piscator tenuirostris

Piscator tenuirostris is a chemistry 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 Piscator tenuirostris rather than just read about it. In short: Piscator tenuirostris is an extinct species of cormorant-like bird, the only known species in the genus Piscator. Discovery Piscator tenuirostris is known from an incomplete rostrum, the anterior end of a premaxilla, found in Hordle, England, in formations dating to the Priabonian, the final age of the Eocene Epoch.

Key takeaways

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

Reference excerpt

Piscator tenuirostris is an extinct species of cormorant-like bird, the only known species in the genus Piscator.

Discovery Piscator tenuirostris is known from an incomplete rostrum, the anterior end of a premaxilla, found in Hordle, England, in formations dating to the Priabonian, the final age of the Eocene Epoch. This holotype is now at the British Museum. It was initially described by Colin Harrison and Cyril A. Walker in 1976, and placed in the family phalacrocoracidae. It was placed in class Aves incertae sedis by Jiří Mlíkovský in 2002. A similar sample was found in the Late Eocene-early Oligocene Jebel Qatrani Formation in Faiyum, Egypt, but whether this sample represents P. tenuirostris, another Piscator species, or a different phalacrocoracid is unknown.

Description Piscator was similar to the extant phalacrocoracidae, a piscivorous family of aquatic birds. Remains were found in the Bracklesham Group in Hordle, England, which dates to the Priabonian, the last age of the Eocene epoch.

Taxonomy The genus was introduced by Cyril A. Walker and Colin Harrison in 1976. It was placed in class Aves incertae sedis by Jiří Mlíkovský in 2002. The word piscator is Latin for "fisherman." Other fossils may also represent species in this genus, but they have not been described as such, with some residing in private collections. P. tenuirostris is the oldest discovered cormorant-like bird in the fossil record. It is the type specimen of its genus, and the only species of Piscator currently described.

Worked examples

Example 1 — a first encounter with Piscator tenuirostris

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

In research: Piscator tenuirostris appears in chemistry 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 Piscator tenuirostris 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: Piscator tenuirostris is common in secondary-school and first-year university syllabi. It links to neighbouring topics Phalacrocoracidae, Prehistoric birds, so understanding it makes those chapters shorter.
In everyday life: Look for Piscator tenuirostris 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.
