Linheraptor

Linheraptor 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 Linheraptor rather than just read about it. In short: Linheraptor is a genus of dromaeosaurid dinosaur which lived in what is now China in the Late Cretaceous. It was named by Xu Xing and colleagues in 2010, and contains the species Linheraptor exquisitus.

Key takeaways

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

Reference excerpt

Linheraptor is a genus of dromaeosaurid dinosaur which lived in what is now China in the Late Cretaceous. It was named by Xu Xing and colleagues in 2010, and contains the species Linheraptor exquisitus. This bird-like dinosaur was less than 2 m (6.5 ft) long and was found in Inner Mongolia. It is known from a single, nearly complete skeleton.

Discovery Researchers announced the discovery of the genus after a nearly complete fossilised skeleton was found in 2008 by Jonah N. Choiniere and Michael Pittman in Inner Mongolia; a more detailed publication is forthcoming. The specimen was recovered from rocks at Bayan Mandahu that belong to the Wulansuhai Formation. The latter includes lithologies that are very similar to the Mongolian Campanian-aged rocks of the Djadokhta Formation which have yielded the closely related dromaeosaurids Tsaagan and Velociraptor. The holotype specimen of Linheraptor, articulated and uncompressed, is one of the few nearly complete skeletons of dromaeosaurid dinosaurs worldwide. The name of the genus refers to the district of Linhe, Inner Mongolia, China where the specimen was discovered, while the specific name, exquisitus, refers to the well-preserved nature of the holotype (IVPP V 16923).

Description Linheraptor was a bird-like theropod dinosaur. It was a dromaeosaurid which measured approximately 1.8 metres (5.9 ft) in length, and weighed up to approximately 25 kilograms (55 lb). At that size, Linheraptor would have been a fast and agile predator, perhaps preying on small ceratopsians. Like all dromaeosaurids, it had an elongated skull, a curved neck, an enlarged toe claw on each foot, and a long tail; Linheraptor was bipedal and carnivorous. The large toe claws may have been used for capturing prey.

Taxonomy

Among its sister taxa, Linheraptor is believed to be most closely related to Tsaagan mangas. Linheraptor and Tsaagan were intermediate between basal and derived dromaeosaurids. The two share several skull details, among which a large maxillary fenestra — an opening in the maxilla, an upper jaw bone — and lack various features of more derived dromaeosaurids such as Velociraptor. Senter (2011) and Turner, Makovicky and Norell (2012) argue that Linheraptor exquisitus is a junior synonym of Tsaagan mangas, but Xu, Pittman et al. (2015) reject this synonymy by responding to the counterarguments proposed using new and existing details of Linheraptor's anatomy. A monographic description of Linheraptor is currently in preparation.

Worked examples

Example 1 — a first encounter with Linheraptor

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

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