Picture on the right shows an example of dorsal pattern variation in four snake species. In this quiz, pictures of two specimens will be shown simultaneously and you have limited time to decide whether the specimens belong to the same species. Note that the snakes in the photos are museum samples and some may be in bad condition. It takes less than five minutes to complete the quiz and participation is allowed only once, so please allocate that time. Your effort is highly valuable for us and we really appreciate your effort to assist us in our experiment. Leer más.
Aquest matí s’han iniciat les tasques per extreure un petit esquelet de fa més 65 milions d’anys d’identitat encara desconeguda a Coll de Nargó, a l’Alt Urgell.
