Martinmiguelia

Martinmiguelia 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 Martinmiguelia rather than just read about it. In short: Martinmiguelia is an extinct genus of Notoungulate, belonging to the family Leontiniidae. It lived during the Middle Eocene, and its fossil remains were found in South America.

Key takeaways

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

Reference excerpt

Martinmiguelia is an extinct genus of Notoungulate, belonging to the family Leontiniidae. It lived during the Middle Eocene, and its fossil remains were found in South America.

Description This animal is only known from skull and mandible remains, and it probably shared similarities with later and better known leontiniids, such as Scarrittia. It was smaller-sized than those derived genera, approximately the size of a sheep. Martinmiguelia was characterized by an archaic dental formula, with a complete dentition (three incisors, one canine, four premolars and three molars) and a quasi-absence of diastema, except for small spaces around the small-sized canines. The molars and premolars were low-crowned (brachydont), a primitive condition for leontinnids. The upper incisors were canine-like and possessed labial girdles, and the second upper incisor was larger than the others.

Classification Martinmiguelia fernandezi was first described in 1995, based on fossils found in the Casa Grande Formation, in the Jujuy Province of Argentina, in terrains dated from the Mustersan (Middle Eocene). Martinmiguelia is considered to be one of the oldest and most basal members of the family Leontiniidae, a group of heavy toxodonts with massive builds. It was related with the Eocene genus Coquenia, and with the Oligocene genus Elmerriggsia.

Worked examples

Example 1 — a first encounter with Martinmiguelia

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

In research: Martinmiguelia 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 Martinmiguelia 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: Martinmiguelia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Eocene mammals of South America, Fossil taxa described in 1995, Fossils of Argentina, so understanding it makes those chapters shorter.
In everyday life: Look for Martinmiguelia 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.
