動物化石 - Dalinghosaurus - 55 cm - 30 cm

Dalinghosaurus 是一种已灭绝的基础蜥蜴类爬行动物，化石在中国的九佛塘组发现。\n\nDalinghosaurus\n\n是一种生活在中国辽宁西部、白垩纪早期（约1.2亿年前）的小型蜥蜴爬行动物，是热河生物群的代表性物种。 Its tail accounted for about two-thirds of its total length, and its hind limbs were significantly longer than its forelimbs. Its claws exhibited adaptations for both running and climbing, and its skeletal features suggest it may have been arboreal. As a key link in the Jehol Biota food chain, it was found in the stomach contents of *Sinosauropteryx*, making it valuable for early lizard evolution research.
