odd-toed ungulate
Let an agent explain odd-toed ungulates and their families, relay biology, evolution and conservation from zoological sources, distinguish them from even-toed ungulates, and route to entries for specific species.
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 odd-toed ungulates and their families, relay biology, evolution and conservation from zoological sources, distinguish them from even-toed ungulates, and route to entries for specific species.
A mammal of the order Perissodactyla, bearing weight on an odd number of toes, comprising the horses, asses and zebras of the family Equidae including the domestic horse and the plains zebra and their hybrids, the rhinoceroses and the tapirs, with about 17 living species and a rich fossil record; odd-toed ungulates digest plant matter by hindgut fermentation and include some of the most endangered large mammals and the domesticated horse, while the registry alias Tulpar is a mythical winged horse.
What it is for: Not applicable; an order of mammals.
It can be explain the order and families; relay biology and evolution; relay conservation status; distinguish from even-toed ungulates.
Distinguishing features
Odd toe count
Hindgut fermentation
Three living families
Domestic horse
What it looks like
Hoofed mammals with one or three weight-bearing toes: horses, rhinos and tapirs.
Physical character
living species: about 17 count
origin: about 56 million years ago - early Eocene
How it is recognised
Perissodactyla
Equidae, Rhinocerotidae, Tapiridae
Even-toed ungulates such as cattle and deer have two or four toes; the Tulpar is mythical

- How should conservation sources be linked?
- The registry entry has merged aliases naming taxa, species and a mythical horse; should they be split off?
