Xiushanosteus mirabilis is the earliest known completely
preserved jawed fish and provides key fossil evidence for
understanding the origin of jaws and the early evolution of
jawed vertebrates.

最早完整保存有颌脊椎动物
目前已知最早的完整保存的有颌鱼类，全长约3厘

区浅海或河口中。奇迹秀山鱼的身体前半部分由
骨板包裹着，胸鳍前方有发达的棘刺，尾巴强有力
，显示它虽然仍为底栖，但已经有较强的游泳能力。
奇迹秀山鱼为研究颌的起源和早期演化提供了确
切证据，是近些年来最重要的古生物学发现之一

The Earliest Completely Preserved Jawed Vertebrate
Xiushanosteus mirabilis is the earliest known jawed fish preserved as
a complete body. This placoderm was about 3cm long and lived in
shallow-marine or estuarine environments in the Chongqing region
around 436 million years ago. The front half of its body was covered
with dermal bones, with prominent spines in front of the pectoral fins
and a powerful tail. These features suggest that, although it was
probably bottom-associated, it was already a capable swimmer.
Xiushanosteus provides direct evidence for the origin and early
evolution of jaws and represents a major recent discovery in
vertebrate paleontology.
