**200-million-year-old pterosaur species discovered in Arizona**
亚利桑那州发现2亿年前翼龙新物种
**Scientists have identified a new species of pterosaur from a jawbone fossil preserved in 209-million-year-old volcanic ash in Arizona's Petrified Forest National Park.**
科学家们从亚利桑那州石化林国家公园2.09亿年前的火山灰中保存的颌骨化石鉴定出一个翼龙新物种。
**Named Eotephradactylus mcintireae ("ash-winged dawn goddess"), the seagull-sized flying reptile represents the earliest known pterosaur in North America from the Late Triassic period.**
这种海鸥大小的飞行爬行动物被命名为"灰翼黎明女神",是北美已知最古老的三叠纪晚期翼龙。
**Smithsonian researchers used advanced CT scanning to analyze the delicate, hollow bones that typically don't fossilize well, revealing unique dental features confirming its new species status.**
史密森尼研究人员使用先进CT扫描技术分析了通常难以完整化石化的中空骨骼,揭示了确认其新物种地位的独特牙齿特征。
**The fossil bed also contained fish scales, teeth, and coprolites (fossilized feces), painting a vivid picture of the ancient river ecosystem in Pangaea's central region.**
化石层中还发现了鱼鳞、牙齿和粪化石,生动描绘了盘古大陆中部古河流生态系统的景象。
**Lead author Dr. Kligman notes this discovery suggests more Triassic pterosaur fossils may be found in similar ancient river deposits worldwide.**
主要作者克里格曼博士指出,这一发现表明全球类似的古河流沉积物中可能蕴藏更多三叠纪翼龙化石。
**Published in PNAS, the study pushes back North America's pterosaur record by 5 million years and offers new insights into early pterosaur evolution.**
这项发表在《美国国家科学院院刊》的研究将北美翼龙记录提前了500万年,为早期翼龙进化提供了新见解。
