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 pterosaurs and their biology, describe major groups and notable genera with sources, distinguish them from dinosaurs and birds, and support learning.

An extinct order of flying reptiles that lived from the Late Triassic to the end of the Cretaceous, the first vertebrates to evolve powered flight, with wings formed by a membrane stretched from an elongated fourth finger, ranging from small forms such as Pterodactylus to giants such as Thanatosdrakon and Quetzalcoatlus, and including crested tapejarids and toothed anhanguerids; pterosaurs are known from fossils, are not dinosaurs, and are studied in palaeontology.

What it is for: Extinct flying reptiles.

It can be explain biology; describe groups and genera; distinguish from dinosaurs; support learning.
