Propalaeotherium was one of the earliest horses, and certainly one of the best known.
Propalaeotherium lived on the forest floor in the great expanses of rainforest, which covered the land in the Eocene.
Propalaeotherium are most closely related to modern horses, and more distantly related to other odd-toed hoofed animals (perissodactyls): the tapirs and rhinos (and the extinct brontotheres and chalicotheres).
Answer: The early horses shown in the series are based on the smaller of two species found in the Messel shales of Germany, Propalaeotherium parvulum, which was 30-35cm at the shoulder.
Answer: Amazingly, some of the fossil Propalaeotherium are so well preserved that we can see their stomach contents and so we know exactly what they ate.
Some of the fossil beetles from the same place are coloured, but this is because their colour is caused by the very fine structure of their shells diffracting the light.
Die Einteilung in Arten ist bis heute durchaus umstritten, einzig unstreitig ist, dass die drei Zebra -Arten untereinander nicht näher als mit den anderen Arten der Familie verwandt sind.
Die Entwicklung der Pferde ist durch Fossilien gut dokumentiert und zeigt wie aus dem hundegroÃen, laubfressenden Waldbewohner Propalaeotherium, der noch mehrere Zehen hatte, über einen Zeitraum von 50 Millionen Jahren, ein grasfressender, pferdegroÃer Bewohner offener Landschaften wurde, der nur noch auf der Spitze einer Zehe läuft.
Die Entwicklung fand hauptsächlich in Nordamerika statt, aber immer wieder erreichten Entwicklungslinien auch die Alte Welt.

Propalaeotherium isselanum is a well-known and unique specimen of the Geisel valley collection and is the logo of the museum.
As a preliminary synthesis of the data base, already in the late 1950s some reconstructional paintings had been made on the north, south and western walls of the museum interior.
In the center of such a painting a particular taxon is presented in its typical landscape and vegetation (gallery forest), for example Lophiodon, Anthracobunodon, Propalaeotherium and Prodissopsalis (northern wall).

They provide evidence of an important period in the evolutionary history of mammals, which were able to develop at a rapid rate after the extinction of the dinosaurs.
The "Messel Propalaeotherium" represents an early European side branch of the horse family tree: they were much smaller than horses today, lived in the rainforest undergrowth and fed on foliage and fruit, as was established from their teeth and stomach contents.
The discovery of an anteater was a huge surprise for palaeontologists, since it originally came from South America.
The largest, Gastornis is as tall as a grown male and weighs up to half a tonne.
There is also Ambulocetus (meaning walking whale), a 3 m long carnivorous water dwelling mammal and Propalaeotherium, an early form of horse.
For each beast there is information on the time period they roamed the earth, their diet, size and weight, their closest living relative and where fossils have been located.

Two species of these tiny forest-living horses are known from Eocene sites in Germany.
Even the stomach contents of Propalaeotherium were preserved, so we know exactly what they ate.
Preservation was so good that when leaves from their stomachs were put under a microscope and shown to a botanist, they couldn't tell that the leaves were 50 million years old.
Take it with a dose of salt, though it seems largely correct.
Episode 1: New Dawn Eocene Messel and others bits of the Eocene world, featuring _Gastornis_, _Leptictidium_ (shown hopping - correctly - and not striding I believe), the primitive primate _Godinotia_, _Propalaeotherium_ and giant Messel ants.
Episode 2: Whale Killer Focuses I think on Late Eocene Asia with _Andrewsarchus_ as main character.

There were forty specimens of the primitive Messel horse Propalaeotherium parvulum whose skeleton measures approximately 50cm in length.
Odd-toed ungulate Hallensia matthesi, crocodile Diplocynodon sp., Kopidodon macrognathus, bat Archaeonycteris pollex, and a large rodent Ailuravus macrurus have also been identified.
