Lyrogoniatites

Lyrogoniatites 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 Lyrogoniatites rather than just read about it. In short: Lyrogoniatitites is a neoglyphioceratoidean ammonite, in the order Goniatitida, related to genera like Alaoceras, Cravenoceras, Dumbarigloria and Pachylyroceras. Description Lyrogoniatites is similar to Neoglyphioceras, but with broader shell and a smaller number (30-60) of longitudinal lirae and with a ventral (hyponomic) sinus and ventrolateral salients (projections) in all growth stages.

Key takeaways

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

Reference excerpt

Lyrogoniatitites is a neoglyphioceratoidean ammonite, in the order Goniatitida, related to genera like Alaoceras, Cravenoceras, Dumbarigloria and Pachylyroceras.

Description Lyrogoniatites is similar to Neoglyphioceras, but with broader shell and a smaller number (30-60) of longitudinal lirae and with a ventral (hyponomic) sinus and ventrolateral salients (projections) in all growth stages. As with Neoglyphioceras the ventral lobe is rather narrow.

Taxonomic relations W.M. Furnish, et al., 2009, in the revised Treatise includes Lyrogoniatites in the neoglyphioceratid subfamily, Lyrogoniatitinae, along with Alaoceras, Caenolyroceras, Dombarigloria, and Pachylyroceras. D. Korn (2006) on the other hand put Lyrogoniatites in the neoglyphioceratacean family Cravenoceratidae instead, and in the subfamily Lyrogoniatitinae along with such as Caenolyroceras and Pachylyroceras. Others, (e.g. GONIAT) also include Lyrogoniatites in the Cravenoceratidae but in the Cravenoceratinae. The older Treatise (Miller, Furnish, and Schindiwold 1957) puts Lyrogoniatites along with Neoglyphioceras in the Goniatitidae and subfamily Neoglyphioceratinae, differentiating the two on the basis of the umbilicus—that of Lyrogoniatites being moderately large, that of Neoglyphioceras being narrow.

Worked examples

Example 1 — a first encounter with Lyrogoniatites

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

In research: Lyrogoniatites 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 Lyrogoniatites 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: Lyrogoniatites is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ammonites of Asia, Cravenoceratidae, Fossils of Kazakhstan, so understanding it makes those chapters shorter.
In everyday life: Look for Lyrogoniatites 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.

Why does Lyrogoniatites matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lyrogoniatites?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
