Indobatrachus

Indobatrachus is a biology 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 Indobatrachus rather than just read about it. In short: Indobatrachus (Greek for "Indian frog") is an extinct genus of frog known from the Early Paleocene (Danian) of India. It contains a single species, Indobatrachus pusillus.

Key takeaways

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

Reference excerpt

Indobatrachus (Greek for "Indian frog") is an extinct genus of frog known from the Early Paleocene (Danian) of India. It contains a single species, Indobatrachus pusillus. Two other species, I. trivialis and I. malabaricus, were also previously described, but these have since been synonymized with I. pusillus. Indobatrachus was a very small frog, only 20 millimetres (0.79 in) long as an adult. It is known from numerous complete but poorly-preserved specimens (known by Richard Owen as "batracholites") from the Intertrappean Beds of Worli Hill, Mumbai. The stratigraphy of the specimens is disputed; they were originally dated to the Early Eocene, but later thought to be latest Cretaceous in age (66 mya). However, more recently, the intertrappean rocks around Mumbai have been dated to the late Danian, around 62.5 million years ago, representing the youngest eruptive event in the western Deccan volcanic province. The taxonomy of this genus is debated; it was previously classified within the Australian frog superfamily Myobatrachoidea by many authors, including Owen, but such a relationship is now considered dubious or untenable, with only some vertebral similarities linking the two groups. Alternatively, it may represent a member of the superfamily Sooglossoidea, another ancient group that is thought to have originated on Insular India during the Cretaceous.

Worked examples

Example 1 — a first encounter with Indobatrachus

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

In research: Indobatrachus 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 Indobatrachus 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: Indobatrachus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Danian genera, Fossil taxa described in 1930, Fossils of India, so understanding it makes those chapters shorter.
In everyday life: Look for Indobatrachus 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.

Frequently asked questions

What is Indobatrachus in simple terms?

Indobatrachus (Greek for "Indian frog") is an extinct genus of frog known from the Early Paleocene (Danian) of India. It contains a single species, Indobatrachus pusillus.

Why does Indobatrachus matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Indobatrachus?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
