Tangaroasaurus

Tangaroasaurus 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 Tangaroasaurus rather than just read about it. In short: Tangaroasaurus is an extinct genus of squalodontid whale from the Miocene of New Zealand. It contains a single species, Tangaroasaurus kakanuiensis.

Key takeaways

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

Reference excerpt

Tangaroasaurus is an extinct genus of squalodontid whale from the Miocene of New Zealand. It contains a single species, Tangaroasaurus kakanuiensis. Similar to Basilosaurus and its close relative Squalodon, it was originally thought to be a species of marine reptile. Parts of the holotype are presumably lost. Its name comes from Tangaroa, the Māori god of the sea, while the suffix -saurus comes from the Latin word for reptile, the group that Tangaroasaurus was originally placed in. The type fossil was found in a grey clay deposit at All Day Bay and consists of a jaw bearing a few teeth, measuring 5 cm (2.0 in) each. The original describer of the type specimen, William Blaxland Benham, described it as a reptile, either a dinosaur such as Megalosaurus or an late surviving ichthyosaur. The genus was described as an odontocete cetacean in 1979 by R. E. Fordyce. The status of the genus as a cetacean remains under discussion.

Fossils known from the same geological formation, the All Day Bay formation and Gee Greensand Formation, include an unnamed species of Squalodelphinidae and a species of Prosqualodon.

Worked examples

Example 1 — a first encounter with Tangaroasaurus

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

In research: Tangaroasaurus 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 Tangaroasaurus 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: Tangaroasaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fossil cetaceans misidentified as reptiles, Fossil taxa described in 1935, Fossils of New Zealand, so understanding it makes those chapters shorter.
In everyday life: Look for Tangaroasaurus 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.
