Hyaenictitherium

Hyaenictitherium 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 Hyaenictitherium rather than just read about it. In short: Hyaenictitherium is an extinct genus of hyaenids that lived throughout Africa, Asia, and possibly Europe during the Late Miocene and Pliocene. The type species, H. hyaenoides, was similar in size to a striped hyena, whereas the smaller H. minimum was close in size to a jackal.

Key takeaways

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

Reference excerpt

Hyaenictitherium is an extinct genus of hyaenids that lived throughout Africa, Asia, and possibly Europe during the Late Miocene and Pliocene. The type species, H. hyaenoides, was similar in size to a striped hyena, whereas the smaller H. minimum was close in size to a jackal. Hyaenictitherium may represent a paraphyletic group. Some authors argue that Hyaenotherium (Semenov, 1989) is a junior synonym of Hyaenictitherium, and that species belonging to this genus (H. wongii and H. ebu) should be included in Hyaenictitherium.

Taxonomy Hyaenictitherium was erected by Kretzoi (1938) with H. hyaenoides as the type species. H. venator was later described by Semenov (1989). Werdelin & Solounias (1991) in their review of Hyaenidae included H. parvum, H. namaquensis, and H. pilgrimi in this genus. H. minimum was later described by Bonis et al. (2005). H. barbarum was tentatively assigned to Hyaenictitherium by Geraads et al. (2010). Some authors include species assigned to the genus Hyaenotherium, including H. wongii and H. ebu, under Hyaenictitherium.

Palaeobiology

Palaeoecology H. wongii had an ecological niche very similar to Ictitherium viverrinum, with which it competed.

Worked examples

Example 1 — a first encounter with Hyaenictitherium

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

In research: Hyaenictitherium 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 Hyaenictitherium 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: Hyaenictitherium is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cenozoic mammals of Africa, Cenozoic mammals of Asia, Fossil taxa described in 1938, so understanding it makes those chapters shorter.
In everyday life: Look for Hyaenictitherium 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.
