Mount Stephen trilobite beds

Mount Stephen trilobite beds 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 Mount Stephen trilobite beds rather than just read about it. In short: The Mount Stephen trilobite beds (UNSM locality 14s) are a series of fossil strata on Mount Stephen, British Columbia that contain exceptionally preserved fossil material. Part of the same stratigraphic unit as the Burgess Shale deposit, many non-mineralized parts (such as anomalocarid claws, sponges, and trilobite legs) are preserved; in addition, a high density of trilobite fossils is present.

Key takeaways

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

Reference excerpt

The Mount Stephen trilobite beds (UNSM locality 14s) are a series of fossil strata on Mount Stephen, British Columbia that contain exceptionally preserved fossil material. Part of the same stratigraphic unit as the Burgess Shale deposit, many non-mineralized parts (such as anomalocarid claws, sponges, and trilobite legs) are preserved; in addition, a high density of trilobite fossils is present.

History

The trilobite beds were the first Burgess Shale locality to be discovered. The richness of fossils in the Field area was first identified by workers associated with the construction of the Trans-Canada railway, which had (somewhat controversially) been routed through the Kicking Horse valley. Richard McConnell, of the Geological Survey of Canada, was pointed to the beds by a railway worker whilst mapping the geology around the railway line in September 1886. Several unusual fossils were subsequently described from this site, including sponges, worms, and the appendages of the unusual Anomalocaris, identified at that time as the bodies of crabs. These fossils prompted Charles Doolittle Walcott to make forays into the area, and led to his discovery of the Walcott Quarry on Fossil Ridge.

Stratigraphy The trilobite beds are in the Campsite Cliff member, and contain the marker trilobite Ogygopsis.

Location

The strata are located on Mount Stephen in British Columbia.

Worked examples

Example 1 — a first encounter with Mount Stephen trilobite beds

Start with the simplest possible case. Write down what Mount Stephen trilobite beds 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 Mount Stephen trilobite beds 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 Mount Stephen trilobite beds 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 Mount Stephen trilobite beds

In research: Mount Stephen trilobite beds 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 Mount Stephen trilobite beds 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: Mount Stephen trilobite beds is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cambrian paleontological sites, Paleontology in Canada, Paleozoic paleontological sites of North America, so understanding it makes those chapters shorter.
In everyday life: Look for Mount Stephen trilobite beds 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.
