Paralonectes

Paralonectes 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 Paralonectes rather than just read about it. In short: Paralonectes is an extinct genus of thalattosaurian reptile which lived in the Early or Middle Triassic of what is today British Columbia. The type and only species is P. merriami.

Key takeaways

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

Reference excerpt

Paralonectes is an extinct genus of thalattosaurian reptile which lived in the Early or Middle Triassic of what is today British Columbia. The type and only species is P. merriami. The genus name is derived from Ancient Greek and means "shore swimmer", and the species epithet is in honor of J. C. Merriam, a paleontologist who has done extensive work on Triassic marine reptiles.

Discovery and description Paralonectes was described in 1993 in the same publication that described the sympatric species Thalattosaurus borealis and Agkistrognathus campbelli. All three taxa were discovered in the rocks of the Sulphur Mountain Formation. All known specimens of Paralonectes were transported to and prepared at the Royal Tyrrell Museum of Paleontology. The holotype includes a mostly complete skull with an associated mandible, several vertebrae, ribs, an ischium, and a few limb bones, and it was given the designation TMP 89.127.1. Two referred specimens (TMP 89.127.2 and TMP 91.120.21) include several additional isolated skull elements.

Classification The classification of Thalattosauria has been controversial, and it is not known with confidence to which other reptiles they are closely related. They have been suggested to be relatives of Sauropterygia, Archosauromorpha, or possibly being part of a more primitive lineage. A cladogram summarizing the internal interrelationships of thalattosaurs is shown below.

Worked examples

Example 1 — a first encounter with Paralonectes

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

In research: Paralonectes 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 Paralonectes 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: Paralonectes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 1993, Fossils of Canada, Middle Triassic reptiles of North America, so understanding it makes those chapters shorter.
In everyday life: Look for Paralonectes 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 Paralonectes in simple terms?

Paralonectes is an extinct genus of thalattosaurian reptile which lived in the Early or Middle Triassic of what is today British Columbia. The type and only species is P. merriami.

Why does Paralonectes 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 Paralonectes?

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.
