Palimphyes

Palimphyes 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 Palimphyes rather than just read about it. In short: Palimphyes is an extinct genus of marine ray-finned fish known from the Paleogene period. It was a euzaphlegid, an extinct family of scombroid fish related to the escolars and snake mackerels.

Key takeaways

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

Reference excerpt

Palimphyes is an extinct genus of marine ray-finned fish known from the Paleogene period. It was a euzaphlegid, an extinct family of scombroid fish related to the escolars and snake mackerels.

Taxonomy

The various species lived as deepwater mesopelagic predators throughout the Tethys and Paratethys oceans, with fossils of ten species found in earliest Eocene to Oligocene strata of the Swiss Alps, the Carpathian and Caucasus Mountains, Iran, India, and Turkmenistan. The following species are known:

P. chadumicus Daniltshenko, 1960 - early Oligocene (Rupelian) of the North Caucasus, Russia (Pshekha Formation) (=P. longirostratus Daniltshenko, 1980) P. elongatus (de Blainville, 1818) (type species) - Rupelian of Canton Glarus, Switzerland (Glarner Schiefer Formation) P. lanceolatus (Simionescu, 1904) - Rupelian of Romania (=Krambergeria Simionescu, 1904) P. leptosomus (Arambourg, 1967) - Middle/Late Eocene (?Priabonian) of Iran (Pabdeh Formation) (=Dipterichthys leptosomus Arambourg, 1967) P. misrai Sahni & Choudhary, 1972 - early Eocene (Ypresian) of Rajasthan, India (Kapurdi Formation) ?P. nematophorus (Arambourg, 1967) - ?Priabonian of Iran (Pabdeh Formation) (=Dipterichthys nematophorus Arambourg, 1967) P. originis (Ciobanu, 1976) - Rupelian of Romania (=Dipterichthys originis Ciobanu, 1976) P. palaeocenicus Daniltshenko, 1968 - earliest Eocene (Ypresian) of Turkmenistan (Danata Formation) P. pinnatus Daniltshenko, 1962 - middle Eocene (Lutetian) of Georgia (Dabakhan Formation) P. pshekhaensis Bannikov, 1993 - middle Eocene (Bartonian) of Krasnodar Krai, Russia (Kuma Formation) P. stolyarovi Bratishko & Udovychenko, 2013 - Rupelian of Kazakhstan (Uzunbas Formation) & Crimea (Kyzyl-Dzhar Beds) [otolith] Indeterminate species are also known from the early Oligocene-aged Menilite Formation of Poland and the Czech Republic.

Worked examples

Example 1 — a first encounter with Palimphyes

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

In research: Palimphyes 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 Palimphyes 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: Palimphyes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bartonian genera, Euzaphlegidae, Fossil taxa described in 1835, so understanding it makes those chapters shorter.
In everyday life: Look for Palimphyes 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.

Frequently asked questions

What is Palimphyes in simple terms?

Palimphyes is an extinct genus of marine ray-finned fish known from the Paleogene period. It was a euzaphlegid, an extinct family of scombroid fish related to the escolars and snake mackerels.

Why does Palimphyes matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Palimphyes?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
