Dinosaurs & Prehistoric Life · Unit 2
Famous Dinosaurs
Tyrannosaurus, Triceratops, Stegosaurus and the other stars
A small number of species do almost all the work in the public imagination, and most of them are known from far fewer specimens than their fame suggests.
The unit covers Tyrannosaurus, Triceratops, Stegosaurus, the sauropod giants and the raptors - what is actually known about each, and where the popular picture has been overtaken by evidence.
This unit breaks down into 19 short steps and 111 questions, starting at difficulty 1 and building to 3. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
