Olive Press News Spain Prehistoric Catalunya; one of the last strongholds of the dinosaurs. Share THE presence of fossilised remains of dinosaurs and bones, footprints and eggs in Catalunya is astounding. Now, thanks to two investigations by the Catalan Institute of Paleontology Miquel Crusafont (ICP), 219 icnitas (fossil footprints) have been described. The fossilised footprints are of tetrapod vertebrates and arthropod invertebrates that lived in the territory of present-day Catalunya about 240 million years ago, before the dinosaurs. Among the remains described is the Puigventos ichnite (Olesa de Montserrat, Barcelona), of particular importance and interest and the result of the chance discovery of a hiker who, on April 7 2016, found a footprint that appeared to be carved into the rock in an area known as Puigventos.
