Reference excerpt

The Potrerillos Formation is a geologic formation in Mexico. It preserves fossils dating back to the Early Paleocene period.

Description The Potrerillos Formation was subdivided into five members by McBride (1974), with the second highest, the Upper Mudstone Member. Foraminifera in the lower members indicate a Maastrichtian age, while fossils in the upper members indicate a Paleocene age. Fossil remains are abundant and include transported remains of corals, gastropods, bivalves, shark teeth, and bone fragments.

Fossil content The following fossils have been reported from the formation:

Bivalves Venericardia (Baluchicardia) francescae Venericardia sp. Cephalopods Cimomia haltomi Elimia cf. trigemmata

Worked examples

Example 1 — a first encounter with Potrerillos Formation, Mexico

Start with the simplest possible case. Write down what Potrerillos Formation, Mexico 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 Potrerillos Formation, Mexico 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 Potrerillos Formation, Mexico 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 Potrerillos Formation, Mexico

In research: Potrerillos Formation, Mexico 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 Potrerillos Formation, Mexico 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: Potrerillos Formation, Mexico is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coahuila, Cretaceous Mexico, Cretaceous–Paleogene boundary, so understanding it makes those chapters shorter.
In everyday life: Look for Potrerillos Formation, Mexico 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.
