Jugulator amplissimus

Jugulator amplissimus is a science 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 Jugulator amplissimus rather than just read about it. In short: Jugulator is an extinct genus of mammals from the Cretaceous of North America. It contains one species, Jugulator amplissimus.

Key takeaways

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

Reference excerpt

Jugulator is an extinct genus of mammals from the Cretaceous of North America. It contains one species, Jugulator amplissimus. A eutriconodont, it is known from the Cedar Mountain Formation, and is both a large sized and possibly ecologically specialised taxon, showcasing the diversity of mammals in the Mesozoic.

Description Jugulator is known primarily from isolated teeth and dentaries. The species is most distinctive in regards to its large size, being among the largest mammals in the region, some lower molars exceeding 5 mm in length and with an estimated body weight of about 750 g. The medial lower incisor is greatly enlarged, with a mitten-shaped crown that bears sharp cutting surfaces.

Phylogeny Always recognised as a triconodontid eutriconodont, the most recent phylogenetic studies recover Jugulator as the sister taxon of a clade comprising Volaticotherium, Ichthyoconodon, Triconolestes, and Argentoconodon, known as Volaticotherini. Cladogram after Gaetano & Rougier, 2011:

Biology Jugulator is noted as being a rather large mammal for Mesozoic standards. Combined with the general adaptations for carnivory that eutriconodonts display, it is safe to say that it was a predator of other vertebrates like mammals, lizards and small dinosaurs. Other large eutriconodonts like Repenomamus and Gobiconodon show evidence of scavenging and direct predation on such creatures, so it is likely that Jugulator also displayed these behaviours.

Ecology Jugulator occurs in the mid-Cretaceous deposits of the Cedar Mountain Formation, where several of North America's more iconic dinosaurs like Utahraptor and Cedarosaurus occur. A large variety of mammal species are known from here as well, including other eutriconodonts like Astroconodon and Corviconodon as well as multituberculates like Cedaromys and Janumys and several therian mammals such as Montanalestes and Atokatheridium. These diverse mammal faunas offer a transition from dominant taxa in the Early Cretaceous and the multituberculate and therian dominated laurasian mammalian faunas of the Late Cretaceous.

Worked examples

Example 1 — a first encounter with Jugulator amplissimus

Start with the simplest possible case. Write down what Jugulator amplissimus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Jugulator amplissimus 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 Jugulator amplissimus 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 Jugulator amplissimus

In research: Jugulator amplissimus appears in science 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 Jugulator amplissimus 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: Jugulator amplissimus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cretaceous mammals of North America, Early Cretaceous mammals, Fossil taxa described in 1998, so understanding it makes those chapters shorter.
In everyday life: Look for Jugulator amplissimus 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.
