Tadzhikosuchus

Tadzhikosuchus 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 Tadzhikosuchus rather than just read about it. In short: Tadzhikosuchus (also spelt Tajikosuchus) is an extinct genus of neosuchian crocodyliform from the Late Cretaceous of Tajikistan. Three species have been named: the type species T. macrodentis, described by Efimov in 1982 from the lower Santonian-age Upper Cretaceous Ialovachsk Formation of Kansai, Tajikistan, in the Fergana Basin of Tajikistan; T. neutralis from the same location, by Efimov in 1988; and T. kizylkume…

Key takeaways

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

Reference excerpt

Tadzhikosuchus (also spelt Tajikosuchus) is an extinct genus of neosuchian crocodyliform from the Late Cretaceous of Tajikistan. Three species have been named: the type species T. macrodentis, described by Efimov in 1982 from the lower Santonian-age Upper Cretaceous Ialovachsk Formation of Kansai, Tajikistan, in the Fergana Basin of Tajikistan; T. neutralis from the same location, by Efimov in 1988; and T. kizylkumensis from Turonian-age rocks of the Upper Cretaceous Bissekty Formation of Dzharakhuduk, Uzbekistan, by Nesov and colleagues in 1989. However, a 2000 review by Glenn Storrs and Mikhail Efimov could not differentiate between the species based on their type material, and recommended grouping the specimens of all three species under T. macrodentis. They also could not determine how Tadzhikosuchus and the contemporaneous Zhyrasuchus were related, or even if they were synonyms, due to the poor fossils available. The name of Tadzhikosuchus is derived from the Russian spelling of Tajikistan. To date, Tadzhikosuchus is mostly known from partial dentaries, which were initially considered to have been very similar to Prodiplocynodon (a crocodyloid) by Efimov. However, since dentaries are not known for Prodiplocynodon, this conclusion was considered questionable by Jeremy Martin and Massimo Delfino in 2010. They instead suggested that it may have belonged to the Paralligatoridae, which was common in Asia at the time.

Worked examples

Example 1 — a first encounter with Tadzhikosuchus

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

In research: Tadzhikosuchus 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 Tadzhikosuchus 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: Tadzhikosuchus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bissekty Formation, Fossil taxa described in 1982, Fossils of Uzbekistan, so understanding it makes those chapters shorter.
In everyday life: Look for Tadzhikosuchus 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.
