Proa valdearinnoensis

Proa valdearinnoensis 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 Proa valdearinnoensis rather than just read about it. In short: Proa is a genus of basal styracosternan iguanodont known from the Early Cretaceous Escucha Formation (lower Albian stage) of Teruel Province, Spain. Discovery and naming It contains a single species, Proa valdearinnoensis.

Key takeaways

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

Reference excerpt

Proa is a genus of basal styracosternan iguanodont known from the Early Cretaceous Escucha Formation (lower Albian stage) of Teruel Province, Spain.

Discovery and naming It contains a single species, Proa valdearinnoensis. The generic name is from the Spanish word "proa" (meaning "prow"), which alludes to the pointed shape of the animal's predentary bone; while the specific name is derived from Val de Ariño, the traditional name for the coal mines near where the first fossils were found. The animal was described on the basis of three partial skeletons and several skull elements from different individuals.

Description Proa is distinguished from other basal hadrosauriforms (especially other iguanodontids) in having a predentary that reaches the rostral margin, with divergent lateral processes. It can also be diagnosed by a unique combination of characters: dentary tooth row convex dorsally in lateral view; dentary tooth row extending caudal to the base of the coronoid process; platform between the dentary tooth row and the base of the coronoid process; coronoid process expanded along rostral and caudal margins; maxilla lacks a rostrodorsal process; quadrate straight in lateral view; ilium with dorsal margin convex dorsally, non-pendant supraacetabular process, and postacetabular process that tapers without a break in slope along its dorsal margin; cranial pubic process concave along its dorsal margin but lacks expansion of distal end.

Phylogeny McDonald et al. (2012) recover Proa at the base of Hadrosauriformes along with Iguanodon. In his osteology of Hypselospinus, Norman (2015) recovered Proa in a monophyletic Iguanodontidae as closer to the East Asian Bolong and Jinzhousaurus than to other European members of Iguanodontidae. Verdu et al (2017) recovered it as part of Eurasian clade including the Asian Xuwulong, Altirhinus, Koshisaurus and Gongpoquansaurus. Proa was found in the most derived position as sister taxon to Batyrosaurus.

Worked examples

Example 1 — a first encounter with Proa valdearinnoensis

Start with the simplest possible case. Write down what Proa valdearinnoensis 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 Proa valdearinnoensis 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 Proa valdearinnoensis 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 Proa valdearinnoensis

In research: Proa valdearinnoensis 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 Proa valdearinnoensis 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: Proa valdearinnoensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Albian dinosaurs, Ankylopollexia, Dinosaur species, so understanding it makes those chapters shorter.
In everyday life: Look for Proa valdearinnoensis 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.
