The collection shows an interesting selection of marine fossils unique in the world, such as the Alcoveria brevis, a holotype, a species discovered at our site; a jellyfish fossil, with an incredible fossilization if we take into account that its body contains 90% water; the controversial Cosesaurus aviseps, an ancestor of a flying reptile from the Jurassic period, or one of the oldest insects of Catalonia.
