Pirate Gold Coins Treasures of the Jurassic is honored to present this "Cave Lion" Skull found in Siberia Russia 370,000 Years Old! Panthera spelaea, also known as the Eurasian cave lion, European cave lion, or steppe lion, is an extinct Panthera species that evolved in Europe probably after the third Cromerian interglacial stage, less than 600,000 years ago. Phylogenetic analysis of fossil bone samples revealed that it was highly distinct and genetically isolated from the modern lion (Panthera leo) occurring in Africa and Asia. Analysis of morphological differences and mitochondrial data support the taxonomic recognition of Panthera spelaea as a distinct species that diverged from the lion about 1.9 million years ago. The oldest known bone fragments were excavated in Yakutia and radiocarbon dated at least 62,400 years old. It became extinct about 13,000 years ago.
