Matanomictis

Matanomictis 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 Matanomictis rather than just read about it. In short: Matanomictis (lit. 'Matanomadh marten') is an extinct genus of mustelid that is known from Oligocene and possibly Miocene of Maniyara Fort Formation, India. The genus contains a single species, Matanomictis maniyarensis.

Key takeaways

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

Reference excerpt

Matanomictis (lit. 'Matanomadh marten') is an extinct genus of mustelid that is known from Oligocene and possibly Miocene of Maniyara Fort Formation, India. The genus contains a single species, Matanomictis maniyarensis. It is currently the oldest known mustelid from Indian Subcontinent.

Discovery and naming The holotype of Matanomictis, IITR-SB 5135, a right mandible with p4 and m1, was discovered 1km south of the Mata no Madh village, the remains of dugongids like Bharatisiren indica are also known from the type locality. In 2008, Thewissen and Bajpai described the mandible as a new genus and species of mustelid, Matanomictis maniyarensis. The generic name "Matanomictis" is a combination of two words, "Matanom" after the Matanomadh village, which is located 1km north of the type locality, and "ictis" is the Greek word for martens. The specific name "maniyarensis" is after the Maniyara Fort Formation, the geological formation where the type locality is situated.

Description Matanomictis is designated as the oldest known mustelid from Indian subcontinent and one of the oldest known mustelid in Eurasia. It was a small sized mustelid, with its m1 dimensions of 6.6 x 3.0 mm. It is also suggested that Matanomictis had a Otter-like lifestyle as the depositional environment in which the holotype was found was clearly near-shore marine.

Classification Matanomictis can be distinguished from other early carnivorans like amphicyonids like Pseudocyonopsis and Cynelos as both of these are larger, lack a diastema between p4 & m1 and have larger carnassial talonids, and early ursids like Pachycynodon as they are bunodont and have lower carnassial talonids compared to Matanomictis. Matanomictis can be confidently assigned to mustelids as its lower carnassial has a wide, long trigonid with a high protoconid, the m1 trigonid being only slightly longer than talnoid, a large hypoconid on a rounded talonid, and a diastema between the p4 and m1 teeth. Notably, the carnassial trigonid is lower and broader compared to Palaeogale, which was originally thought to be a mustelid but is now considered as a indeterminate carnivoran. However, it lacks the specialized features of any mustelid subfamily; for instance, it has a low carnassial as seen in lutrines, but absence of crowding of the premolars(both of which are diagnostic of lutrine subfamily), has a secondary cusp in last premolar as seen in melines, it lacks a high trigonid with a small metaconid and a short talonid but has anterior position of the metaconid, further distinguishing Matanomictis from other mustelids.

Paleoecology Matanomictis is currently one of the two known mammalian vertebrates known from the Oligocene Maniyara Fort Formation, the other being a dugongid, Bharatisiren indica.

Worked examples

Example 1 — a first encounter with Matanomictis

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

In research: Matanomictis 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 Matanomictis 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: Matanomictis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 2008, Fossils of India, Miocene mammals of Asia, so understanding it makes those chapters shorter.
In everyday life: Look for Matanomictis 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.
