Tatankacephalus

Tatankacephalus 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 Tatankacephalus rather than just read about it. In short: Tatankacephalus is a basal genus of nodosaurid dinosaur that lived during the Early Cretaceous. Its length has been estimated at 7 meters (23 ft).

Key takeaways

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

Reference excerpt

Tatankacephalus is a basal genus of nodosaurid dinosaur that lived during the Early Cretaceous. Its length has been estimated at 7 meters (23 ft). Its fossil has been collected from the Cloverly Formation (Aptian-Albian) of central Montana, USA, during 1996, 1997 and 1998, in the region of the Middle Dome in Wheatland County. The type species is T. cooneyorum, described by William L. Parsons and Kristen Parsons in 2009. The genus name is derived from Oglala tatanka, "bison" and Greek kephale, "head", in reference to the rounded head form. The specific name honours the family of John Patrick Cooney. The holotype is MOR 1073, a partial skull with an estimated total undamaged length of 32 centimetres, lacking the lower jaws. Also some ribs, osteoderms and a tooth have been recovered. The front of the snout is missing. The specimen is that of an adult individual. According to the authors the fossil has not been deformed by compression, allowing to distinguish it from Sauropelta edwardsorum, another ankylosaurian found in the same formation. The head is domed and the eye-sockets are round. A large bone ridge runs transversely across the back of the head. The fossil skull itself no longer had any teeth in it but a single tooth was found, lacking the cingulum. Two osteoderms were found; one was intact. It has a length of 137 and a width of 115 millimetres. It is hollow and conical. A cladistic analysis found that Tatankacephalus was a basal member of the Ankylosauridae and relatively closely related to Gastonia. Basal traits include the retention of premaxillary teeth in the front of the upper jaws and a skull opening, the lateral temporal fenestra, that was not covered by the skull armour. A new cladistic analysis performed by Thompson et al., 2011 suggests that Tatankacephalus is a basal nodosaurid.

Worked examples

Example 1 — a first encounter with Tatankacephalus

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

In research: Tatankacephalus 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 Tatankacephalus 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: Tatankacephalus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Albian dinosaurs, Cloverly Formation, Dinosaur genera, so understanding it makes those chapters shorter.
In everyday life: Look for Tatankacephalus 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 Tatankacephalus in simple terms?

Tatankacephalus is a basal genus of nodosaurid dinosaur that lived during the Early Cretaceous. Its length has been estimated at 7 meters (23 ft).

Why does Tatankacephalus 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 Tatankacephalus?

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.
