Loreleia eucingulata

Loreleia eucingulata 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 Loreleia eucingulata rather than just read about it. In short: Loreleia eucingulata is an extinct species of coelacanth lobe-finned fish known from the Middle Triassic (Ladinian age) Calcaire à Cératites Formation of France. It is the only species in the genus Loreleia, known from a well-preserved, articulated skull and skeleton.

Key takeaways

Loreleia eucingulata belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Loreleia eucingulata to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Loreleia eucingulata is an extinct species of coelacanth lobe-finned fish known from the Middle Triassic (Ladinian age) Calcaire à Cératites Formation of France. It is the only species in the genus Loreleia, known from a well-preserved, articulated skull and skeleton. Using microCT scans, an ossified lung was identified in this species and the closely related Graulia branchiodonta, known from the same formation. This structure may have allowed it to transmit sound pressure from the lung to the inner ear.

Discovery and naming The Loreleia fossil material was discovered in outcrops of the Calcaire à Cératites Formation—part of the Muschelkalk assigned to the Ceratites praenodosus biozone—near Sarraltroff in Moselle, France. The specimen is housed in the Natural History Museum of Geneva, where it is permanently accessioned as specimen MHNG-GEPI-V5789. The specimen consists of a nearly complete skeleton and skull preserved in anatomical articulation. In 2026, Luigi Manuelli and colleagues described Loreleia eucingulata as a new genus and species of fossil coelacanth (order Coelacanthiformes) based on these fossil remains, establishing MHNG-GEPI-V5789 as the holotype specimen. The generic name, Loreleia, alludes to the mythical figure Loreley in Lorraine folklore, the French region near the type locality. The specific name, eucingulata, combines the Greek prefix εὖ (eu-), meaning 'prominent' or 'well', with the Latin word cingulum, meaning 'belt' or 'girdle', in references to the elongate pectoral girdle observed in this species.

Classification

To test the affinities and relationships of Loreleia, Mannuelli and colleagues (2026) scored it in the phylogenetic matrix of Ferrante & Cavin (2025). They recovered Loreleia alongside the coeval Graulia and the Early Triassic Dobrogeria of Romania, in an unresolved polytomy at the base of Latimeriidae (the family containing the modern coelacanth genus, Latimeria). The authors remarked that previous phylgoenetic work had identified Graulia as a member of the family Mawsoniidae, which forms the sister group to Latimeriidae. They concluded that the precise relationships of the basalmost mawoniid and latimeriid taxa are not stable, and that Loreleia, Graulia, and Dobrogeria should be regarded as basal Latimerioidei incertae sedis, pending more detailed analyses in the future. The results of their phylogenetic analysis are shown in the cladogram below:

Worked examples

Example 1 — a first encounter with Loreleia eucingulata

Start with the simplest possible case. Write down what Loreleia eucingulata 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 Loreleia eucingulata 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 Loreleia eucingulata 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 Loreleia eucingulata

In research: Loreleia eucingulata 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 Loreleia eucingulata 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: Loreleia eucingulata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coelacanths, Fossil taxa described in 2026, Fossils of France, so understanding it makes those chapters shorter.
In everyday life: Look for Loreleia eucingulata 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.
