Hotel Mar Nummus

More than 150 million years, the Sierra de Albarracín was covered by the Tethys Sea, precursor to the present Mediterranean Sea. In Mar Nummus learn how a fossil is formed, the tool that serves the palaeontologists to find and explore what life was like millions of years ago. And you can also watch a rich and varied display of fossils of creatures that lived in this vast sea such as crocodiles, sponges, brachiopods, bivalves, gastropods, echinoderms or ammonites, as Albarracinites albarraciniensis, a new species named after having been found in Albarracin vicinity and unique on the planet so far.

And to surprise you even more you will see a copy of the largest known predator, the impressive Liopleurodon, a giant aquatic reptile that lived in the Jurassic seas and whose teeth were almost twice the size as those of a Tyrannosaurus rex, served to hunt most cohabitant marine animals.
