Telmatornis

Telmatornis 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 Telmatornis rather than just read about it. In short: Telmatornis is a valid prehistoric bird genus which has been placed in Charadriiformes. It apparently lived in the Late Cretaceous; its remains were found in the early Maastrichtian (c.71-68 million years ago) Navesink Formation of New Jersey.

Key takeaways

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

Reference excerpt

Telmatornis is a valid prehistoric bird genus which has been placed in Charadriiformes. It apparently lived in the Late Cretaceous; its remains were found in the early Maastrichtian (c.71-68 million years ago) Navesink Formation of New Jersey. A single species is included today, Telmatornis priscus. There is some uncertainty about its taxonomic affiliation. For some time it was united with other taxa of aquatic birds from around the Cretaceous-Paleocene boundary in the form taxon "Graculavidae", the supposed "transitional shorebirds", but this group is now known to be artificial. Some sources erroneously claim it was allied with ducks and geese. The reason for this is that the early anseriform Anatalavis rex was for some time included in Telmatornis. Hope (2002), however, noted that Telmatornis shares many characters with members of Charadriiformes, the ancient and diverse group of modern birds that includes for example gulls, auks and waders. A cladistic analysis of the forelimb skeleton (Varricchio 2002) found it highly similar to the great crested grebe and unlike the painted buttonquail (now known to be a basal charadriiform lineage), the black-necked stilt (a more advanced charadriiform), or the limpkin (a member of the Grui suborder of Gruiformes), namely in that its dorsal condyle of the humerus was not angled at 20°–30° away from long axis of the humerus. The analysis did not result in a phylogenetic pattern but rather grouped some birds with similar wing shapes together while others stood separate. It is thus unknown whether this apparent similarity to grebes represents an evolutionary relationship, or whether Telmatornis simply had a wing convergent on that of grebes and moved it like they do.

Worked examples

Example 1 — a first encounter with Telmatornis

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

In research: Telmatornis 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 Telmatornis 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: Telmatornis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird genera, Birds of North America, Charadriiformes, so understanding it makes those chapters shorter.
In everyday life: Look for Telmatornis 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.
