Gwyneddosaurus

Gwyneddosaurus 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 Gwyneddosaurus rather than just read about it. In short: Gwyneddosaurus is a possibly invalid genus of extinct aquatic tanystropheid reptile. The type species, G. erici was described in 1945 by Wilhelm Bock, who identified it as a coelurosaurian dinosaur related to Podokesaurus (at the time, "podokesaurids" were thought to be coelurosaurians).

Key takeaways

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

Reference excerpt

Gwyneddosaurus is a possibly invalid genus of extinct aquatic tanystropheid reptile. The type species, G. erici was described in 1945 by Wilhelm Bock, who identified it as a coelurosaurian dinosaur related to Podokesaurus (at the time, "podokesaurids" were thought to be coelurosaurians). Its remains were found in the Upper Triassic Lockatong Formation of Montgomery County, eastern Pennsylvania, and the holotype includes skull fragments, several vertebra, ribs, gastralia, partial shoulder and hip bones, and several forelimb and hindlimb elements found in soft shale, while the paratype includes a femur and a tibia. The type specimen is ANSP 15072 and it was discovered by Bock's four-year-old son while the paratype is only listed as ?(ASNP coll.). It was not a large animal; the type skeleton was estimated by Bock as 18 centimetres (7.1 in) long, and its thigh bone was only 23 millimeters long (0.91 in). Friedrich von Huene assigned the animal to Protorosauria in 1948 as the smallest known member of the group, finding it to be most like Macrocnemus. Steel (1970) classified it as a theropod dinosaur, whereas Olsen and Baird (1986) identified it as a chimera of mixed remains from a coelacanth and possibly the tanystropheid Tanytrachelos; Olsen and Flynn (1989) later modified this interpretation, describing the type specimen of Gwyneddosaurus as a "gastric ejection" (regurgitation) composed of Tanytrachelos bones and possibly scraps of a coelacanth. They noted that this would make Gwyneddosaurus a senior synonym of Tanytrachelos, and recommended conserving the younger but better-represented genus.

Worked examples

Example 1 — a first encounter with Gwyneddosaurus

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

In research: Gwyneddosaurus 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 Gwyneddosaurus 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: Gwyneddosaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aquatic reptiles, Fossil taxa described in 1945, Late Triassic reptiles of North America, so understanding it makes those chapters shorter.
In everyday life: Look for Gwyneddosaurus 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.
