Hylaeobatrachus

Hylaeobatrachus 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 Hylaeobatrachus rather than just read about it. In short: Hylaeobatrachus is an extinct genus of prehistoric salamander, known from the Early Cretaceous of Europe. The type species H. croyii is known from the Sainte-Barbe Clays Formation at the Iguanodon locality of Belgium, and was described by Louis Dollo.

Key takeaways

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

Reference excerpt

Hylaeobatrachus is an extinct genus of prehistoric salamander, known from the Early Cretaceous of Europe. The type species H. croyii is known from the Sainte-Barbe Clays Formation at the Iguanodon locality of Belgium, and was described by Louis Dollo. An unnamed Hylaeobatrachus-like taxon has also been reported from Las Hoyas, Spain. Both localities are of Barremian age. Hylaeobatrachus belongs to the crown group of modern salamanders, though its exact relationship with modern salamander groups is uncertain. It was neotenic, like some modern salamanders.

Worked examples

Example 1 — a first encounter with Hylaeobatrachus

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

In research: Hylaeobatrachus 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 Hylaeobatrachus 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: Hylaeobatrachus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cretaceous salamanders, Early Cretaceous amphibians, Fossil taxa described in 1884, so understanding it makes those chapters shorter.
In everyday life: Look for Hylaeobatrachus 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.
