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