- Aragosaurus-IUCA Group, University of Zaragoza footprints found dinosaur fossils most modern in Europe.
The tracks are in sandstones lying areas along rivers from different localities of the Aragonese Pyrenees and Catalan.
The fossil record of dinosaurs just before the extinction of dinosaurs 65 million years ago, “is scarce”.
Researchers at Aragosaurus-IUCA at the University of Zaragoza have led research that has helped to find the footprints ? fossil footprints? modern dinosaur of Europe in sandstones lying areas along rivers from different localities of the Aragonese Pyrenees and Catalan, which prove that dinosaurs lived in this part of the world until the time when the large meteor struck of the Cretaceous-Tertiary boundary.
This is explained by the University of Zaragoza in a statement, which pointed out that the fossil record of dinosaurs just before their extinction 65 million years “ is scarce and is limited to a few places the world, one of them the Pyrenees”.

The group of researchers from the University of Zaragoza, the Autonomous University of Barcelona and the Catalan Institute of Palaeontology Miquel Crusanfont (ICP) document recent decades dinosaurs and on a recent publication in the PlosOne have shown that dinosaurs hadrosaurs, known as’ Peaks duck ‘, lived in the last few thousand years of the Cretaceous.
The study was conducted from their footprints, evidence whose importance is that these can form the only one living organism while traveling in the time the rock was forming . So while fossil bones can be eroded and redeposited in modern rocks, in the case of the footprints it does not, but had to be produced at the time that dinosaurs lived.From the University of Zaragoza detailed studies have pointed out that for more than ten years in the outcrops where the Cretaceous-Tertiary boundary has revealed that these footprints are abundant hadrosaurs in sandstones formed in the channels of rivers.
However, “ from a geological level does not meet again “, which would imply that hadrosaurs “were relatively abundant on the banks of rivers of 65.5 million years ago, to disappear from the fossil record abruptly. “
An identification problem
Aragon The academic institution has indicated that” is problematic to relate the footprints with a particular species “and that” it is very difficult to find the footprints next to dinosaur that produced “, although” there are several hypotheses. “
So, in the same geological formation where the footprints found dinosaurs described in Aren Arenysaurus hadrosaurs (Huesca) and Pararhabdodon in Isona (Lleida).
“They are certainly two good candidates could have left their imprints in the mud 65.5 million years ago in what is now known as the Pyrenees “, have held the same sources.
