Qingjiang biota

Qingjiang biota 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 Qingjiang biota rather than just read about it. In short: The Qingjiang biota are a major discovery of fossilized remains dating from the early Cambrian period approximately 518 million years ago. The remains consist at least 20,000 individual specimens, and were discovered near the Danshui River in the Hubei province of China in 2019.

Key takeaways

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

Reference excerpt

The Qingjiang biota are a major discovery of fossilized remains dating from the early Cambrian period approximately 518 million years ago. The remains consist at least 20,000 individual specimens, and were discovered near the Danshui River in the Hubei province of China in 2019. The site is particularly notable due to both the large proportion of new taxa represented (approximately 53% of the specimens), and due to the large amount of soft-body tissue of the ancient specimens that was preserved, likely due to the organisms being rapidly covered in sediment prior to fossilization, that allowed for the detailed preservation of even fragile, soft-bodied creatures such as jellyfish. Shelly fossils found at the site include trilobites, radiodonts, lobopods, bradoriids, brachiopods, hyolithids, mollusks, chancelloriids, kinorhynchs, priapulids, and articulated sponge spicules. The site is a Burgess Shale type preservation, and has been widely compared to the Burgess Shale in terms of the site's richness and significance. The discovery has been described as one of the most significant of its kind in the last 100 years. Initial publications regarding the site stated that 4,351 of the collected specimens had been examined, and 101 species had been identified, 53 of which were new to science. Talks are reportedly underway with local government to protect the site to ensure the longevity of continued research on the deposited specimens.

Worked examples

Example 1 — a first encounter with Qingjiang biota

Start with the simplest possible case. Write down what Qingjiang biota 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 Qingjiang biota 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 Qingjiang biota 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 Qingjiang biota

In research: Qingjiang biota 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 Qingjiang biota 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: Qingjiang biota is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cambrian China, Fossils of China, Lagerstätten, so understanding it makes those chapters shorter.
In everyday life: Look for Qingjiang biota 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.
