Tehuelchesaurus

Tehuelchesaurus 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 Tehuelchesaurus rather than just read about it. In short: Tehuelchesaurus () is a genus of macronarian or turiasaurian sauropod dinosaur from the Late Jurassic (Oxfordian to Tithonian) of Argentina. It is named in honor of the Tehuelche people, native to the Argentinian province of Chubut, where it was first found.

Key takeaways

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

Reference excerpt

Tehuelchesaurus () is a genus of macronarian or turiasaurian sauropod dinosaur from the Late Jurassic (Oxfordian to Tithonian) of Argentina. It is named in honor of the Tehuelche people, native to the Argentinian province of Chubut, where it was first found.

Description

It was a moderately large (possibly 15 metres (49 ft) long) cetiosaur-like sauropod found in the Late Jurassic (Tithonian) Cañadon Calcareo Formation at Fernandez Estancia, Chubut Province, Patagonia, Argentina; known from the holotype MPEF-PV 1125 (Museo Paleontologico Egidio Fergulio), a 50% complete skeleton, lacking a skull, but including dorsal, sacral and caudal vertebrae, parts of the forelimbs and hindlimbs, parts of the shoulder girdle and pelvis, some rib fragments, and skin impressions. Tehuelchesaurus is most similar to Omeisaurus from the Middle Jurassic of China, but is distinguished by the shape of the coracoid, the stouter radius and ulna, and the shapes of the pubis and ischium; all the dorsal vertebrae have pseudopleurocoels (deep depressions in the centra but without internal chambers) and opisthocoelous centra, unlike in Barapasaurus and Patagosaurus. The length of the entire neck and tail are not known, but based on other proportions (humerus 1.14 metres (3.7 ft) long; femur 1.53 metres (5.0 ft) long; scapula 1.75 metres (5.7 ft) long; ischium 1.01 metres (3.3 ft) long; ilium 1.12 metres (3.7 ft); pubis 94.3 centimetres (37.1 in) long), Tehuelchesaurus was probably about 15 metres (49 ft) long. It was named by Rich, Vickers-Rich, Gimenez, Cuneo, Puerta & Vacca in 1999. The type species is Tehuelchesaurus benitezii (), named after Aldo Benitez, who discovered the holotype. An equal weights analysis of Eusauropoda by Mannion et al. (2019) found that Tehuelchesaurus was a basal member of Turiasauria.

Worked examples

Example 1 — a first encounter with Tehuelchesaurus

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

In research: Tehuelchesaurus 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 Tehuelchesaurus 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: Tehuelchesaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dinosaur genera, Dinosaurs of Argentina, Fossil taxa described in 1999, so understanding it makes those chapters shorter.
In everyday life: Look for Tehuelchesaurus 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.
