Schleitheimia

Schleitheimia 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 Schleitheimia rather than just read about it. In short: Schleitheimia (named after the type locality of Schleitheim), is an extinct genus of sauropodiform sauropodomorph dinosaur, from the Gruhalde Member of Klettgau Formation of Switzerland. The type species, Schleitheimia schutzi was formally described in 2020.

Key takeaways

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

Reference excerpt

Schleitheimia (named after the type locality of Schleitheim), is an extinct genus of sauropodiform sauropodomorph dinosaur, from the Gruhalde Member of Klettgau Formation of Switzerland. The type species, Schleitheimia schutzi was formally described in 2020.

Discovery and naming The type material was collected between 1952 and 1954 by Emil Schutz. They were donated to the University of Zürich in 1955. In 1986, most of the material was described by Peter Galton, who referred them all to the species Plateosaurus engelhardti. In 2020, Oliver Rauhut, Femke Holwerda and Heinz Furrer redescribed most of Schutz's remains, as well as some remains in the collections of the Museum zu Allerheiligen in Schaffhausen and new remains from an excavation in 2016 led by Holwerda. They found that the earlier found remains represented a new genus and species, which they named Schleitheimia schultzi, honoring the type locality and the discoverer of the type remains. The 2016 finds were not referred. Finds made by Schultz near Hallau-Schwärzibuck were considered to represent a different previously unknown taxon and remained unnamed. The holotype, PIMUZ A/III 550, was found in a layer of the Klettgau Formation dating from the Norian. It consists of a partial right ilium. Several other bones from the general locality were designated as paratypes. Because they are consistent in morphology, the describers referred all of them to the same taxon, if not the same individual.

Description The holotype of Schleitheimia shows a number of autapomorphies, unique derived traits. There is a broad, rounded ridge on the iliac blade that ends in a large, rounded expansion on the ilium. The fourth tronchanter of the ilium is very robust. The crista tibiofibularis of the femur is broad and there is no posteriorly facing shelf is present lateral to the crista.

Classification A phylogenetic analysis conducted by Rauhut and colleagues found Schleitheimia to be a derived sauropodiform closely related to Sauropoda, or a basal member of that clade, depending on the definition used (node or stem based). A cladogram from that analysis is shown below:

Worked examples

Example 1 — a first encounter with Schleitheimia

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

In research: Schleitheimia 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 Schleitheimia 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: Schleitheimia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dinosaur genera, Dinosaurs of Europe, Fossil taxa described in 2020, so understanding it makes those chapters shorter.
In everyday life: Look for Schleitheimia 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.

Frequently asked questions

What is Schleitheimia in simple terms?

Why does Schleitheimia matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Schleitheimia?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
