Uruguayodon

Uruguayodon 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 Uruguayodon rather than just read about it. In short: Uruguayodon is an extinct genus of proterotheriid from the middle Pleistocene of Uruguay. It is known from the type and only species U. alius, named by Corona and colleagues in 2019 for dentaries and a partial postcrania from the Raigón Formation.

Key takeaways

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

Reference excerpt

Uruguayodon is an extinct genus of proterotheriid from the middle Pleistocene of Uruguay. It is known from the type and only species U. alius, named by Corona and colleagues in 2019 for dentaries and a partial postcrania from the Raigón Formation. Uruguayodon represents one of the latest occurrences of Proterotheriidae, with only Neolicaphrium representing other remains from the Pleistocene to possibly Holocene.

Description This animal would have been very similar to other proterotheriids, such as Anisolophus or Diadiaphorus. Uruguayodon possessed slender and elongated legs, equipped with three toes (the middle one of which was well developed). The skull was equipped with a rather short and high snout, with fairly elongated nasal bones. The molar had closely spaced internal tubercles but, in contrast to Anisolophus, the last lower molar was characterized by paraconid and paralophid in a lingually peripheral position; the metaflexis was smooth and there was no entoflexis.

Classification Uruguayodon was described in 2019, based on fossil remains found in Uruguay, in the San José member of the Raigón Formation. Another mammal has been found in the formation, Charruatoxodon, a toxodontid notoungulate described in 2022. The fossils of Uruguayodon had previously been ascribed to the genus Anisolophus, but a redescription allowed them to be attributed to a new genus and species. Uruguayodon is a derived member of the Proterotheriidae, a group of litoptern mammals, which during the Cenozoic developed evolutionary convergence with the equids, particularly with regards to their legs. Uruguayodon is the second known proterotheriid known from the Pleistocene, after Neolicaphrium. Below is a phylogenetic tree of the Proterotheriidae, based on the work of McGrath et al. 2020, showing the position of Uruguayodon.

Worked examples

Example 1 — a first encounter with Uruguayodon

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

In research: Uruguayodon 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 Uruguayodon 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: Uruguayodon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ensenadan, Fossil taxa described in 2019, Fossils of Uruguay, so understanding it makes those chapters shorter.
In everyday life: Look for Uruguayodon 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 Uruguayodon in simple terms?

Why does Uruguayodon 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 Uruguayodon?

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.
