Lohuecosuchus

Lohuecosuchus 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 Lohuecosuchus rather than just read about it. In short: Lohuecosuchus (meaning "Lo Hueco crocodile") is an extinct genus of allodaposuchid eusuchian crocodylomorph that lived during the Late Cretaceous (late Campanian to early Maastrichtian) in what is now Spain and southern France.

Reference excerpt

Lohuecosuchus (meaning "Lo Hueco crocodile") is an extinct genus of allodaposuchid eusuchian crocodylomorph that lived during the Late Cretaceous (late Campanian to early Maastrichtian) in what is now Spain and southern France.

Description The anatomy of the endocranium (braincase) of L. megadontos was found to be similar to crown-crocodylians, revealing that the acute sense of olfaction and low frequency hearing found in living crocodylians likely originated along the stem-line.

Classification Lohuecosuchus is a member of the clade Allodaposuchidae, a group of eusuchians that lived in southern Europe during the Late Cretaceous. Two species of Lohuecosuchus were described in 2015. The type species, Lohuecosuchus megadontos, was recovered from the Lo Hueco fossil site of the Villalba de la Sierra Formation in the municipality of Fuentes, Cuenca Province at Castilla-La Mancha of central Spain. The species name megadontos is composed of the Greek words "mega" (meaning big) and "odon" (meaning tooth), in reference to the relatively large size of the teeth. The second species, Lohuecosuchus mechinorum, was found at the Fox-Amphoux fossil site of the Grès à Reptiles Formation in the Department of Var in southeastern France, and was named after the discoverers of the holotype, Patrick and Annie Mechin. Lohuecosuchus was both synchronic and sympatric (lived at the same time and place) with another allodaposuchid species, Agaresuchus fontisensis. Lohuecosuchus is also closely related to Allodaposuchus, another genus from southern Europe that includes several species. However, a 2021 phylogenetic analysis considering additional postcranial material recovered Allodaposuchus as paraphyletic with respect to Agaresuchus and Lohuecosuchus, and suggested that both Agaresuchus and Lohuecosuchus belong within the genus Allodaposuchus proper, which would render them as junior synonyms of Allodaposuchus. The cladogram from Blanco's 2021 study is shown below:

Worked examples

Example 1 — a first encounter with Lohuecosuchus

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

In research: Lohuecosuchus 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 Lohuecosuchus 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: Lohuecosuchus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Allodaposuchidae, Campanian life, Cretaceous France, so understanding it makes those chapters shorter.
In everyday life: Look for Lohuecosuchus 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.
