Tatankaceratops

Tatankaceratops 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 Tatankaceratops rather than just read about it. In short: Tatankaceratops (meaning "bison horned face") is a controversial genus of herbivorous chasmosaurine ceratopsid dinosaur that lived during the Late Cretaceous period (latest Maastrichtian stage, about 66 million years ago) in what is now the upper Hell Creek Formation, in South Dakota. It is known from a single partial skull housed at the Black Hills Institute, BHI 6226, described by Christopher J.

Key takeaways

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

Reference excerpt

Tatankaceratops (meaning "bison horned face") is a controversial genus of herbivorous chasmosaurine ceratopsid dinosaur that lived during the Late Cretaceous period (latest Maastrichtian stage, about 66 million years ago) in what is now the upper Hell Creek Formation, in South Dakota. It is known from a single partial skull housed at the Black Hills Institute, BHI 6226, described by Christopher J. Ott and Peter L. Larson in 2010 as the type species Tatankaceratops sacrisonorum. In 2011, Nick Longrich published a paper containing a brief re-evaluation of Tatankaceratops. He suggested that the genus appeared to possess a bizarre mix of characteristics from adult and juvenile Triceratops specimens; the animal's small size and short, slender brow horns are consistent with the animal being a juvenile, but the gnarled bone and fusion of skull elements to one another are typical of old adult ceratopsids. The elongate nose horn meanwhile was characteristic of Triceratops, and specifically, the highly advanced T. prorsus. Longrich also noted that this animal could represent a dwarf species of Triceratops or simply a specimen of the aforementioned genus with a developmental disorder which caused it to stop growing prematurely. Other paleontologists, including Thomas R. Holtz, Jr., have written that they "strongly suspect" Tatankaceratops is merely a juvenile specimen of Triceratops. Authors of subsequent studies involving triceratopsins have not considered it a valid genus.

Worked examples

Example 1 — a first encounter with Tatankaceratops

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

In research: Tatankaceratops 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 Tatankaceratops 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: Tatankaceratops is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chasmosaurinae, Dinosaur genera, Dinosaurs of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Tatankaceratops 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.
