Vagaceratops

Vagaceratops 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 Vagaceratops rather than just read about it. In short: Vagaceratops (meaning "wandering (vagus, Latin) horned face", in reference to its close relationship with Kosmoceratops from Utah) is a genus of chasmosaurine ceratopsid dinosaur which lived during the Late Cretaceous period (late Campanian) in what is now Alberta. Its fossils have been recovered from the Upper Dinosaur Park Formation.

Key takeaways

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

Reference excerpt

Vagaceratops (meaning "wandering (vagus, Latin) horned face", in reference to its close relationship with Kosmoceratops from Utah) is a genus of chasmosaurine ceratopsid dinosaur which lived during the Late Cretaceous period (late Campanian) in what is now Alberta. Its fossils have been recovered from the Upper Dinosaur Park Formation. It is sometimes included in the genus Chasmosaurus as Chasmosaurus irvinensis instead of being recognized as its own genus.

History In 2010, paleontologist Scott D. Sampson and colleagues named Vagaceratops (from the Dinosaur Park Formation, whose sole species, C. irvinensis, was formerly placed in Chasmosaurus), as well as Kosmoceratops and Utahceratops (from the Kaiparowits Formation) in the same article. These genera, which were considered unusual compared to typical members of their group, were part of a spate of ceratopsian discoveries in the early 21st century, when many new taxa were named (a 2013 study stated that half of all valid genera were named since 2003, and the decade has been called a "ceratopsid renaissance").

Description

Vagaceratops was a medium-sized ceratopsian, reaching 4.5 m (15 ft) in length and weighing 1.2 t (1.3 short tons). It is known primarily from three fossil skulls. Although the general structure was typical of ceratopsids (i.e. a parrot-like beak, large neck frill, and nasal horn) it has some peculiarities. The skulls are characterized by a reduced supraorbital horn, brow horns that are reduced to low bosses and a larger snout compared to related animals. Vagaceratops had smaller parietal fenestrae than most ceratopsids and had a strange configuration of epoccipitals (bones surrounding the frill). It possessed ten epoccipitals, eight of which were centrally flattened, curved forward and upward and fused together to form a jagged margin along the back of the frill. The frill was shorter and more square-shaped than other chasmosaurines, being wider than it was long.

Classification

Vagaceratops was named by Scott D. Sampson, Mark A. Loewen, Andrew A. Farke, Eric M. Roberts, Catherine A. Forster, Joshua A. Smith, and Alan L. Titus in 2010, and the type species is Vagaceratops irvinensis. This species was originally described as a species of Chasmosaurus (C. irvinensis) in 2001. Its relationships remain debated. Vagaceratops has variously been allied with Kosmoceratops or with Chasmosaurus. The cladogram below is the phylogeny of the Chasmosaurinae by Brown et al. (2015):

Recently it has been suggested that Chasmosaurinae had a deep evolutionary split between a Chasmosaurus clade and a Pentaceratops clade. Vagaceratops was hypothesized to be the last member of the Chasmosaurus clade from northern Laramidia, with the last representative of the clade being its close relative Kosmoceratops.

Worked examples

Example 1 — a first encounter with Vagaceratops

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

In research: Vagaceratops 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 Vagaceratops 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: Vagaceratops is common in secondary-school and first-year university syllabi. It links to neighbouring topics Campanian dinosaurs, Chasmosaurinae, Dinosaur Park Formation, so understanding it makes those chapters shorter.
In everyday life: Look for Vagaceratops 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.
