Thrinaxodon Col

Thrinaxodon Col is a science 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 Thrinaxodon Col rather than just read about it. In short: Thrinaxodon Col (85°12′S 174°19′W) is a rock col 2 nautical miles (3.7 km) southeast of Rougier Hill. The col is along the ridge that trends southward from Rougier Hill in the Cumulus Hills, Queen Maud Mountains.

Key takeaways

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

Reference excerpt

Thrinaxodon Col (85°12′S 174°19′W) is a rock col 2 nautical miles (3.7 km) southeast of Rougier Hill. The col is along the ridge that trends southward from Rougier Hill in the Cumulus Hills, Queen Maud Mountains. The name was proposed to Advisory Committee on Antarctic Names (US-ACAN) in 1971 by geologist David H. Elliot of the Ohio State University Institute of Polar Studies.

Geology This col is an important vertebrate fossil locality at which at least a dozen specimens of the mammal-like reptile Thrinaxodon were found. The fossiliferous sedimentary strata exposed at Thrinaxodon Col consist of alternating mudstones and sandstones of the lower Fremouw Formation. At this location, the base of the Fremouw Formation overlies a younger diabase sill. Diabase sills and dikes cross-cut the Fremouw Formation throughout the Thrinaxodon Col area and region. The sandstones and mudstones exposed at Thrinaxodon Col are coupled together as fluvial fining-upward cycles. An individual cycle consists of a basal fluvial sandstone that grades upward into an upper overbank mudstone. An unconformity separates the top of the upper mudstone from the overlying basal sandstone of the overlying cycle. For example, the lowermost sandstone-mudstone cycle consists of a basal 1.3-metre (4.3 ft)-thick coarse-grained sandstone that grades upward into a 12-metre (39 ft)-m-thick medium-grained sandstone. The medium-grained sandstone contains claystone clasts, quartz pebbles, and fossil logs. Overlying and associated with the underlying sandstones is a 6 m of green-gray siltstone and mudstone with abundant fossil rootlets near the top.

Fossils Thrinaxodon Col is a Triassic vertebrate fossil locality from which fossil jaws and articulated skeletons have been collected. This fossil locality has yielded a far richer and well-preserved collection of vertebrate fossils than fossil localities associated Coalsack Bluff. Twelve of 14 specimens of Thrinaxodon liorhinus were collected from Thrinaxodon Col along with part of a large dicynodont tusk, specimens of Prolacerta broomi, and unidentified cynodontia. At Thrinaxodon Col, the oldest vertebrate fossils occur in a sandstone bed about 7-metre (23 ft) above the top of the basal log-bearing sandstone. The Permian-Triassic boundary lies within this 7-metre (23 ft)-thick interval above the log-bearing sandstone and below the first appearance of vertebrate fossils. The Thrinaxodon liorhinus remains occur in Triassic sandstone that fills the upper portion of a paleochannel."

Worked examples

Example 1 — a first encounter with Thrinaxodon Col

Start with the simplest possible case. Write down what Thrinaxodon Col claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Thrinaxodon Col 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 Thrinaxodon Col 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 Thrinaxodon Col

In research: Thrinaxodon Col appears in science 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 Thrinaxodon Col 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: Thrinaxodon Col is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dufek Coast, Dufek Coast geography stubs, Mountain passes of the Ross Dependency, so understanding it makes those chapters shorter.
In everyday life: Look for Thrinaxodon Col 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.
