Funcusvermis

Funcusvermis 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 Funcusvermis rather than just read about it. In short: Funcusvermis is an extinct genus of stem-caecilian from the Late Triassic of Arizona. It is based on a large sample of jaws and other skull and postcranial fragments, discovered in an approximately 220 million years old layer of rock in the Blue Mesa Member of the Chinle Formation at Petrified Forest National Park.

Key takeaways

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

Reference excerpt

Funcusvermis is an extinct genus of stem-caecilian from the Late Triassic of Arizona. It is based on a large sample of jaws and other skull and postcranial fragments, discovered in an approximately 220 million years old layer of rock in the Blue Mesa Member of the Chinle Formation at Petrified Forest National Park. There is a single species, called Funcusvermis gilmorei. The identity of Funcusvermis as a gymnophionan amphibian is supported by a range of traits, including a long additional tooth row in the jaw, a fused maxillopalatine bone in the skull, and a modified jaw with a pseudodentary and pseudoangular. Small femora (thigh bones) indicate that legs were still present in Funcusvermis, despite its modern relatives being completely legless. Funcusvermis is the oldest known gymnophionan, and has the largest known sample of fossils referred to the group. Previously, both records were held by Eocaecilia micropodia, an amphibian from the Early Jurassic Kayenta Formation of Arizona. The discovery of Funcusvermis provides a strong link between caecilians and other lissamphibians (frogs and salamanders), as well as extinct dissorophoid temnospondyls such as Gerobatrachus. It supports the consensus hypothesis for lissamphibian evolution, with Lissamphibia as a monophyletic group with a single common ancestor among the dissorophoids. Consequently, the anatomy of Funcusvermis helps to compare and contrast alternative hypotheses for lissamphibian origins. For example, a 2017 study proposed that caecilians were related to Chinlestegophis, a stereospondyl from strata of the Chinle Formation in Colorado. This study was scrutinized and its conclusions were rejected by the description of Funcusvermis. The genus name translates to "funky worm", in reference to the funk song of the same name by the Ohio Players. The species name honors collections manager Ned Gilmore of the Academy of Natural Sciences of Drexel University in Philadelphia, Pennsylvania, United States.

Worked examples

Example 1 — a first encounter with Funcusvermis

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

In research: Funcusvermis 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 Funcusvermis 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: Funcusvermis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinle fauna, Fossil taxa described in 2023, Gymnophiona, so understanding it makes those chapters shorter.
In everyday life: Look for Funcusvermis 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.
