Qué es la PaleontologÍa

Fossils are evidence of life from the past They can be the bodies of living organisms Their bones their shells or their leaves They can also be the result of their activity such as footprints also called ignites The feces or coprolites the eggs Fossils are found in rocks and are the result of a process called fossilization Fossilization usually results from rapid burial that prevents the destruction of organisms and allows for their complete or partial preservation Due to burial molds and impressions of the organism can also form in the rock Paleontology is the science that studies past life through fossils Paleontologists are researchers who discover fossils in rocks They extract them using appropriate tools and methods They prepare and clean them in the laboratory Removing the excess rocky material they restore and reconstruct them if they are fragmented and investigate them The result of all this work is disseminated through scientific journals but also in the form of news that almost daily They appear in the media The University of Zaragoza has a long tradition of paleontology research Its work focuses on Aragonese sites of international relevance such as Arén Murero Daroca and Galve But their researchers also participate in excavation campaigns They are held all over the world Many of the fossils displayed in this exhibition are the result of their work and allow us to reconstruct life on the planet Earth Since it originated about 3.8 billion years ago
