Spea labreae

Spea labreae 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 Spea labreae rather than just read about it. In short: Spea labreae is an extinct species of North American spadefoot toad (family Scaphiopodidae) in the genus Spea, known from Pleistocene–Holocene-dated fossils collected from the La Brea Tar Pits in California, United States. The bones were excavated in 1929 but remained undescribed until their description in 2026.

Key takeaways

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

Reference excerpt

Spea labreae is an extinct species of North American spadefoot toad (family Scaphiopodidae) in the genus Spea, known from Pleistocene–Holocene-dated fossils collected from the La Brea Tar Pits in California, United States. The bones were excavated in 1929 but remained undescribed until their description in 2026. S. labreae was about seven percent larger than extant species of Spea.

Worked examples

Example 1 — a first encounter with Spea labreae

Start with the simplest possible case. Write down what Spea labreae 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 Spea labreae 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 Spea labreae 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 Spea labreae

In research: Spea labreae 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 Spea labreae 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: Spea labreae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil taxa described in 2026, Frog stubs, Pleistocene amphibians, so understanding it makes those chapters shorter.
In everyday life: Look for Spea labreae 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.
