Stone Pages' Archaeonews reports in this issue, among other interesting archaeological news, that mural art has been found in Coliboaia cave, at Bihor County, northwest Romania, by local speleologists.
The findings have been confirmed by an specialist team, lead by Jean Clottes, dating them provisionally between 23,000 and 35,000 years ago, in the Aurignacian or Gravettian periods.
The art depicts several animals in black paint, including a bison, a horse, a possible feline, two bear heads and two rhinoceroses. There are several engravings as well

As far as I know, it is the easternmost case of Paleolithic mural art in Europe.
