Kerberosaurus

Kerberosaurus 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 Kerberosaurus rather than just read about it. In short: Kerberosaurus (meaning "Kerberos lizard") is a genus of saurolophine duckbill dinosaur from the late Maastrichtian-aged (Upper Cretaceous) Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago). It is based on bonebed material including skull remains indicating that it was related to Saurolophus and Prosaurolophus.

Key takeaways

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

Reference excerpt

Kerberosaurus (meaning "Kerberos lizard") is a genus of saurolophine duckbill dinosaur from the late Maastrichtian-aged (Upper Cretaceous) Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago). It is based on bonebed material including skull remains indicating that it was related to Saurolophus and Prosaurolophus.

History In 1984, Yuri Bolotsky and the Amur Complex Integrated Research Institute discovered a large dinosaur bonebed at Blagoveschensk. Most of the remains were of Amurosaurus (a lambeosaurine hadrosaur), but some came from turtles, crocodilians, theropods, nodosaurids, and a saurolophine. The cranial material (holotype AENM 1/319, a braincase, and other skull bones) of the saurolophine was sufficiently distinctive to permit the naming of a new taxon, Kerberosaurus manakini, described twenty years later.

Description Diagnostic characters included narrow frontals, unique form of the braincase, and a well-demarcated division between the area of bone surrounding the nostrils and the bone outside of it. No reconstruction of the fragmentary partial skull was offered. In their cladistic analysis, the authors found Kerberosaurus to be the sister taxon to Saurolophus and Prosaurolophus. It has been estimated to be around 8 meters (26 ft) in length.

Paleobiogeography Bolotsky and Godefroit (2004) found the paleobiogeographic implications interesting. The relationship they described provides additional support for land links and faunal interchange between eastern Asia and North America at the end of the Cretaceous, as the other two genera are either known only in North America or are known from a species there. The "sauroloph" group would have had to split from the nest closest group, the "edmontosaur" group, in the early Campanian, from Asia, and moved west while leaving a splinter population that would lead to Kerberosaurus, then return to Asia at a later point and produce Saurolophus angustirostris.

Paleobiology As a hadrosaurid, Kerberosaurus would have been a large bipedal\quadrupedal herbivore, consuming plant matter with complex dental batteries.

Worked examples

Example 1 — a first encounter with Kerberosaurus

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

In research: Kerberosaurus 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 Kerberosaurus 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: Kerberosaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dinosaur genera, Dinosaurs of Russia, Fossil taxa described in 2004, so understanding it makes those chapters shorter.
In everyday life: Look for Kerberosaurus 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.
