A Quaternary digression



A  skeleton of a small Quaternary horse in a breccia in the midst of the Cretaceous rocks

It is interesting that many Cretaceous limestone sediments have gaps which are filled in by the Quaternary breccia, often containing jumbled bones. Thus the name: the bone breccias. Here is one from the Pula "dinosaur track sites" containing the bones of a small horse (photo credit: B.Krzic):

 The close up: Outlined with red are front legs hooves (heart shape) and the skull.

The age of these "breccia horses" of the genus Equus is late Villafranchian to ? Holsteinian (possibly even late Pleistocene).
