Struthio oldawayi

Struthio oldawayi is a science 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 Struthio oldawayi rather than just read about it. In short: Struthio oldawayi is an extinct species of ostrich from the early Pleistocene in Tanzania and possibly Kenya. Zelenkov et al notes it differs little in morphology from modern ostriches but notably is much larger in size.

Key takeaways

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

Reference excerpt

Struthio oldawayi is an extinct species of ostrich from the early Pleistocene in Tanzania and possibly Kenya. Zelenkov et al notes it differs little in morphology from modern ostriches but notably is much larger in size.

Taxonomy Harrison and Msuya (2005) treated this species as a synonym of S. camelus.

Description Bones of a large ostrich found in the Pleistocene of Kenya may refer to this species. Mass has been roughly estimated at 275 kg, making Struthio oldawayi is one of the largest species of its genus, however those of Pachystruthio were significantly heavier.

Femur A femur of the species was found in Olduvai Gorge and has a length of 400 mm and a minimum shaft width of 64 mm, significantly larger than those of extant ostriches, and notably longer than those of other extinct Struthionidae including Struthio Anderssoni and multiple specimens of Pachystruthio dmanisensis, despite being less robust. This bone is of similar morphology to the extant ostrich despite its larger size. Its femur morphology indicates it may have been fast and agile.

Possible eggs Mikhailov and Zelenkov suggested eggshells from the oospecies Psammornis rothschildi belong to this taxa. Egg fragments measure 3.2–3.3 mm in thickness, although the original thickness may have been near 4 mm. The egg size has been estimated at 25–28 cm (9.8–11.0 in) in length and 19–21 cm (7.5–8.3 in) in width, with a mass of 7 kg (15 lb), making it far larger than modern ostrich eggs and still larger than those of the large ostrich relative Pachystruthio pannonicus.

Worked examples

Example 1 — a first encounter with Struthio oldawayi

Start with the simplest possible case. Write down what Struthio oldawayi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Struthio oldawayi 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 Struthio oldawayi 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 Struthio oldawayi

In research: Struthio oldawayi appears in science 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 Struthio oldawayi 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: Struthio oldawayi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird stubs, Extinct flightless birds, Fossil taxa described in 1933, so understanding it makes those chapters shorter.
In everyday life: Look for Struthio oldawayi 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.
