Hualianceratops

Hualianceratops 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 Hualianceratops rather than just read about it. In short: Hualianceratops is a genus of herbivorous ceratopsian dinosaur that lived about 160 million years ago in the Late Jurassic epoch in what is now western China. The single species, H. wucaiwanensis was described in 2015.

Key takeaways

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

Reference excerpt

Hualianceratops is a genus of herbivorous ceratopsian dinosaur that lived about 160 million years ago in the Late Jurassic epoch in what is now western China. The single species, H. wucaiwanensis was described in 2015. Its size has been compared to that of a spaniel.

Discovery

In 2002, an expedition by the Institute of Vertebrate Paleontology and Paleoanthropology and the George Washington University in the region of Wucaiwan in Xinjiang discovered the skeleton of a small dinosaur. The fossil was prepared by Xiang Lishi, Yu Tao and Ding Xiaoqing. In 2015, the type species Hualianceratops wucaiwanensis was named and described by Han Fenglu, Catherine A. Forster, James M. Clark, and Xu Xing. The generic name combines the Chinese hua, "ornamental", and lian, "face", a reference to the ornamentation of the jaw bones, with ceratops, Latinised Greek for "hornface", a usual suffix in the names of ceratopsians. The specific name refers to the provenance at Wucaiwan, the "five colour bay". The species was named in the electronic publication PLoS ONE and the therefore mandatory Life Science Identifiers are D96319BA-6380-47D6-9512-5BDA15221A00 for the genus and DEEB3095-CB69-47CD-91FC-2D01D9F429D5 for the species. Hualianceratops was one of eighteen dinosaur taxa from 2015 to be described in open access or free-to-read journals. The holotype, IVPP V18641, was found in a layer of the upper Shishugou Formation dating from the Oxfordian. It consists of a partial skeleton with skull and lower jaws. It mainly preserves the rear sides of the head, some sacral vertebrae, the right lower hindlimb, a left calf bone and parts of the left foot.

Description Hulianceratops is a small genus, about 1.2 metres (3.9 ft) long. The skull length was estimated at 25 centimetres (9.8 in). In 2015, several distinguishing traits were established. Five of these were autapomorphies, unique derived qualities. The rear branch of the jugal bone, running below the opening of the infratemporal fenestra, bears a distinctive process obliquely pointing to above and behind. The quadrate bone is robust with an expanded facet contacting the quadratojugal bone. Above the facet with the quadratojugal, the front edge of the quadrate is transversely expanded. Near the lower edge of the quadrate a distinctive notch is present. The dentary bone of the lower jaw is deep and short. Additionally, a unique combination of traits was indicated, that in themselves are not unique. The outer surface of the dentary shows a strongly roughened ornamentation, unlike Chaoyangsaurus and Yinlong but similar to Xuanhuaceratops. The jugal branch below the infratemporal fenestra is transversely expanded, different from Yinlong, but similar to Chaoyangsaurus. The underside of the quadratojugal has grooves contacting the rear branch of the jugal, different from Xuanhuaceratops but similar to Chaoyangsaurus and Yinlong. The maxilla bears at least nine teeth, the dentary at least seven.

Phylogeny In 2015, Hualianceratops was placed in the Chaoyangsauridae. The relationships with other members of its clade could not be resolved.

Worked examples

Example 1 — a first encounter with Hualianceratops

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

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