Tianchisaurus

Tianchisaurus 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 Tianchisaurus rather than just read about it. In short: Tianchisaurus (meaning "heavenly pool lizard"), also invalidly called Tianchiasaurus and "Jurassosaurus", is a genus of ankylosaurian dinosaur from the Late Jurassic (Oxfordian-Kimmeridgian) Toutunhe Formation of China. While many later-diverging ankylosaurids had bony clubs at the tips of their tails, Tianchisaurus likely lacked such a structure.

Key takeaways

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

Reference excerpt

Tianchisaurus (meaning "heavenly pool lizard"), also invalidly called Tianchiasaurus and "Jurassosaurus", is a genus of ankylosaurian dinosaur from the Late Jurassic (Oxfordian-Kimmeridgian) Toutunhe Formation of China. While many later-diverging ankylosaurids had bony clubs at the tips of their tails, Tianchisaurus likely lacked such a structure.

Discovery and naming The holotype (IVPP V. 10614), discovered in 1974, consists of skull fragments, five cervicals, six dorsals, seven sacrals, and three caudals, limb fragments, scutes and some unidentifiable fragments. The type specimen was informally referred to as "Jurassosaurus" after the 1993 film Jurassic Park, and the species epithet nedegoapeferima is formed from the surnames of the film's main stars: Sam Neill, Laura Dern, Jeff Goldblum, Richard Attenborough, Bob Peck, Martin Ferrero, Ariana Richards, and Joseph Mazzello. Director Steven Spielberg, who funded dinosaur research via the non-profit Dinosaur Society donated $25,000 to name the dinosaur in honor of the cast as a "wrap" present at the completion of filming. Dinosaur Society founder, Don Lessem proposed the name Jurassosaurus nedegoaperferkamorum ("ne" for Same Neill, "de" for Laura Dern, "go" for Jeff Goldblum, "a" for Sir Richard Attenborough, etc) Dong Zhiming ultimately discarded the genus name "Jurassosaurus" (which is now a nomen nudum) in favor of Tianchisaurus, but retained the species name honoring the actors. The description paper uses the spellings Tianchiasaurus and Tianchisaurus interchangeably, but is spelled with the extra "a" in the section naming it as a new genus. In 1994, Dong published an erratum stating that Tianchisaurus is the correct name. "Sanghongesaurus", mentioned by Zhao Xijin (1983), is sometimes referred to as a basal ornithischian or a synonym of Tianchisaurus.

Worked examples

Example 1 — a first encounter with Tianchisaurus

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

In research: Tianchisaurus 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 Tianchisaurus 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: Tianchisaurus 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 Tianchisaurus 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 Tianchisaurus in simple terms?

Why does Tianchisaurus 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 Tianchisaurus?

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.
