Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain dinosaurs by group and period, report current science with attribution, support education and museum visits, and correct common misconceptions.

A diverse group of reptiles that first appeared in the Triassic period and dominated terrestrial ecosystems through the Mesozoic, including theropods such as Tyrannosaurus rex, sauropods, ornithischians such as Stegosauria, and living birds, which are their descendants; non-avian dinosaurs became extinct about 66 million years ago.

What it is for: Palaeontology, education and public interest.

It can be classify a dinosaur by group; explain evolution, extinction and birds; report recent discoveries with sources; find museums and fossil sites.

Distinguishing features

Upright stance

Include birds

Non-avian forms extinct

What it looks like

Known from fossils, reconstructions and living birds.

How it is recognised

Fossil skeletons and tracks

Upright limb posture

Pterosaurs and marine reptiles are not dinosaurs

What the second pass must settle

  • Should major groups be separate entries?
  • How should discovery databases be linked?
  • How should fossil laws be localised?
