1. Aurochs (Bos primigenius): The aurochs were ancestors of modern cattle and were known for their large size and impressive horns. They were widespread across Europe and Asia but became extinct in the 17th century due to overhunting and habitat destruction.
2. Woolly Mammoth (Mammuthus primigenius): Woolly mammoths were adapted to cold environments during the Pleistocene epoch. They were covered in dense fur and had long, curved tusks. Mammoths disappeared from Spain around 10,000 years ago as the climate warmed.
3. Cave Bear (Ursus spelaeus): Cave bears were giant bears that inhabited Europe during the Pleistocene. They were larger than modern brown bears and often found shelter in caves. Their population dwindled due to a combination of factors such as climate change and hunting, leading to their extinction around 25,000 years ago.
4. Scimitar-toothed Cat (Homotherium latidens): Scimitar-toothed cats were powerful predators known for their distinctive saber-like upper canine teeth. They were widespread across Europe, Asia, and North America but became extinct during the Pleistocene.
5. Iberian Lynx (Lynx pardinus): While not extinct, the Iberian lynx is critically endangered and was once considered extinct in Spain. It is the most endangered feline species in the world and faces numerous conservation challenges, including habitat loss and hunting.
