On March 13
th, 2020 Slovenian Post Authority issued the fifth stamp of their multi-year
set of "
Mammals fossils in Slovenia"
shows fossil and reconstruction, on the FDC, of
Prohyracodon telleri.
The first stamp of the set issued in
2016
and shown fossil of cave bear.
Prohyracodon telleri is the oldest prehistoric mammal fossil from Motnik village in the
Municipality of Kamnik and also known as a Dwarf Rhinoceros.
The following paragraph was written by Matija Kriznar MSc,
palaeontologist, senior curator Slovenian MNatural History Museum
and was published in a bulletin Nr. 130 of Slovenian Post in 2020.
Motnik and its surrounding area were once the site of coal exploration and mining.
Miners in years past unearthed a variety of fossil remains in the underground tunnels of the area's coal mines.
In the second half of the nineteenth century these included the osseous remains of vertebrates,
which had evidently been quite common.
In 1910 the Viennese palaeontologist Othenio Abel classified the remains of a fossil mammal as belonging to
the new genus and species Meninatherium telleri.
Later forgotten, Meninatherium was rescued from oblivion by the palaeontologist Kurt Heissing,
who on examining remains in Austrian palaeontological collections was of the opinion that they
belonged to the Prohyracodon genus.
As a result, the Motnik fossils gained the new scientific name Prohyracodon telleri,
or "Teller's prohyracodon".
Teller's prohyracodon was a medium large mammal the size of a mouflon.
It lived in the marshy flatlands where coal formed in freshwater basins.
The marshes were also inhabited by crocodiles and other mammals such as Anthracohyus slovenicus.
These remains show that the coal-bearing strata in the Motnik area probably formed approximately 40
million years ago, in the geological period of the late Eocene.
This means that Teller's prohyracodon, like the other Motnik remains, is among the oldest fossil mammals found in Slovenia.
Due to the fact that
Prohyracodons are known from few fragmentary fossils only, it was impossible to make precise
reconstruction of the animal.
Perhaps this is the reason for stamp designer to use reconstruction of similar animal:
Hyracodon nebraskensis,
from German book "
Phylogenie der Mammalia, Stammesgeschichte der Saeugetiere von Eric Thenius" published
in Berlin 1969, fir the stamp and and First-Day-of-Issue Postmark.

Entire skeleton of
Hyracodon nebraskensis can be seen in Natural History Museum of Los Angeles for example.
Hyracodon was a lightly built, pony-like mammal of about 1.5 meters long.
It's skull was large in comparison to the rest of the body.
Hyracodon's dentition resembled that of later rhinoceroses, but it was a much smaller animal and differed very little in
appearance from the primitive horses of which it was a contemporary (32–26 million years ago).
Hyracodons were perhaps the most unusual of the rhinos in that they had long slender limbs and feet.
In this sense they were more horse-like in body proportions than other rhinos although, unlike horses, hyracodonts retained
three toes on all four feet.
