名称：孔子鸟形鸟纲
时代：早白垩世，约1.35亿至1.20亿年前
地点：东北中国的辽阔地层群 Jehol生物群落
地层：义县组、九峰塘组等
标本：自然
体型约为55厘米×40厘米

如照片所示：头颅区相对保存完好，位于身体前端，呈现鸟类典型的小头轮廓；颈部、躯干和肢骨清晰可见；前肢明显拉长，形成翼部结构，翼骨的排列可见；后肢修长，具有适应树栖生活的特征；尾部相对保存良好，在末端可见羽毛或尾羽印痕。

孔子鸟形鸟纲是中生代最重要的早期鸟类之一，是研究从恐龙向鸟类进化、鸟类起飞起源以及早期鸟类生态的重要化石。它生活在早白垩世的湖泊-火山环境中，辽阔地层群 Jehol生物群落所具备的独特快速埋藏条件，使其骨骼、羽毛印痕甚至软组织得以极好地保存。

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.
