名称： Confuciusornithiformes
时代：早白垩纪，大约1.35亿至1.20亿年前
地点：东北中国的峙和生物群落（Jehol Biota）
地层：伊然而、九佛塘组等
标本：自然状态
体型：大约55厘米×40厘米

从照片所示：头骨区域保存相对完好，位于身体前端，展现出鸟类典型的小头部轮廓；颈、躯干和肢骨清晰可见；前肢明显延长形成翼状结构，可观察到翼骨的排列；后肢细长，具有适应树栖生活的鸟类特征；尾部保存相对较好，末端可见羽毛或尾羽印迹。

Confuciusornithiformes 是中生代最重要的早期鸟类之一，是研究从恐龙向鸟类演化、鸟类飞行起源及早期鸟类生态学的重要化石。它生活在早白垩纪的湖泊-火山环境中，峙和生物群落独特且快速的埋葬条件使得其骨骼、羽毛印迹乃至软组织都得以良好保存。

Name: Confuciusornithiformes
Era: Early Cretaceous, approximately 135-120 million years ago
Location: Jehol Biota, Northeast China
Strata: Yixian Formation, Jiufotang Formation, etc.
Specimen: Natural
Body size approximately 55cm x 40cm

As seen in the photographs: The skull area is relatively well-preserved, located at the front of the body, showing the typical small head outline of birds; the neck, trunk, and limb bones are clearly visible; the forelimbs are significantly elongated to form wing structures, and the arrangement of wing bones can be observed; the hind limbs are slender, exhibiting characteristics of birds adapted to arboreal life; the tail is relatively well-preserved, with feather or tail feather imprints visible at the tip.

Confuciusornithiformes is one of the most important early birds of the Mesozoic Era, and is an important fossil for studying the evolution from dinosaurs to birds, the origin of bird flight, and the ecology of early birds. It lived in the lacustrine-volcanic environment of the Early Cretaceous, and the unique rapid burial conditions of the Jehol Biota allowed for the excellent preservation of its bones, feather imprints, and even soft tissues.
