Stegosaurides

Stegosaurides 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 Stegosaurides rather than just read about it. In short: Stegosaurides (meaning "Stegosaurus-shaped") is a genus of herbivorous thyreophoran (perhaps ankylosaurid or possibly stegosaurian) dinosaur. It lived during the Cretaceous.

Key takeaways

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

Reference excerpt

Stegosaurides (meaning "Stegosaurus-shaped") is a genus of herbivorous thyreophoran (perhaps ankylosaurid or possibly stegosaurian) dinosaur. It lived during the Cretaceous. Its fossils were found in the Xinminbao Group near Heishan in Gansu Province in China. These fossils consist of fragmentary material, including dermal spine elements. The genus is occasionally misspelled as "Stegosauroides".

Discovery and species In 1930, Anders Birger Bohlin during the Swedish-Chinese expedition of Sven Hedin excavated fossils at Hui-Hui-Pu, between the Heishan en Ku’an-t’ai-shan mountain ranges, near Xinminbao, in the west of Gansu. These included two vertebrae of about eleven centimetres in length and a dermal spine base. The type species is Stegosaurides excavatus, formally described by Bohlin in 1953. The generic name combines Stegosaurus with the Greek ~eides, "-shaped", in reference to the presumed similarity with the vertebrae of Stegosaurus. The specific name means "hollowed out" in Latin and refers to two large depressions, one each on either side of the spine base. It is currently considered a nomen dubium as the material is so limited.

Phylogeny Bohlin placed Stegosaurides in the Stegosauria. However, later authors often presumed it represented a member of the Ankylosauria, in an indeterminate position. The fossils resemble vertebrae of both groups in having strongly elevated diapophyses, but are more ankylosaur-like in that the neural arch is moderately tall. Uncertainty over the precise age of the Xinminbao Group adds to the difficulty of determining the affinities. Usually it is given as Early Cretaceous when both stegosaurs and ankylosaurs were present, but sometimes as Late Cretaceous when stegosaurs were probably extinct.

Worked examples

Example 1 — a first encounter with Stegosaurides

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

In research: Stegosaurides 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 Stegosaurides 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: Stegosaurides is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ankylosauria, Dinosaur genera, Dinosaurs of China, so understanding it makes those chapters shorter.
In everyday life: Look for Stegosaurides 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 Stegosaurides in simple terms?

Stegosaurides (meaning "Stegosaurus-shaped") is a genus of herbivorous thyreophoran (perhaps ankylosaurid or possibly stegosaurian) dinosaur. It lived during the Cretaceous.

Why does Stegosaurides 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 Stegosaurides?

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.
