Equus neogaeus

[Deleted]

Hi !

Equus neogaeus was a horse that lived in South America until about 7000 years before today, according to this site:

www.ele.net/LaBelle/pampas/pampas.htm

It may have arrived from North America during the intercontinental faunal change.

This is absolutly possible, but I found neogeus more often than neogaeus, so I have no idea.

Oh, I see ... Amerhippus neogeus but Equus neogaeus, so neogaeus would be right. I have changed it, Thank You !

Amerhippus is it subgenus, like Hippotigris is the subgenus of mountain zebra, Equus (Hippotigris) zebra.

The note in the above site, gives reference of the findings in 1995 in the archaeological site by Las Brusquitas River, close to the city of Miramar (Argentina) in the Pampas near Buenos Aires.

The site has been interpreted as camp of hunters and the material recovered in it is a mixture of mostly marine and land mammal remains of entropic origin (some of them with evidence of hunting and butchering) and cultural artefacts. A few species are still present in the area, some are regionally extinct and a few are extinct species.

The stratigraphy and the presence of human artefacts have permitted an accurate date of about 3000 y BP.

Among the mammal remains are those of Equus (Amerhippus), an extinct horse.

Did the neogaeus name mean ''New World'', in reference to the American continent?

[Carlos]

I think so, Rafael:

Neo: greek for NEW
Gaeus is the masculine accordance for Gæa or Gea, the latin name of the Greek Goddess Earth.

So the name of this species (Equus neogaeus) is kind of grammatical nonsense, but the meaning is obvious: THE HORSE FROM THE NEW WORLD

[RSN]

Maybe it was named before the knowledge that horses firts evolved in North America.

Equus vandonii new species of fossil horse from corumba mato grosso do sul brazil De-Souza-Cunha, F. L. 1981

Boletim do Museu Nacional de Rio de Janeiro Geologia (40): 1-19

The 2nd fossil species of the subgenus Amerhippus from Brazil and the 7th spp. discovered in South American is described. This horse collected at Pantanal Mato-Grossense is suggested to be an intermediate species between E. (A.) curvidens [Soua Cunha] and E. (A.) neogeaus (J. Bosa)because of some characteristics of the skull and dentition especially the M1 [molar]. [The new species probably is from the Upper Pleistocene].

Equus vandonii is now classed as the same as Equus (Amerhippus) neogaeus

Maybe it could have been a subspecies, since we have no knowledge about prehistoric creatures coloration (in 99% of cases).
