张氏翼鳕
罗平生物群中体型最大的基干辐鳍鱼
类捕食者之一
张氏翼鳕体长约30厘米，体型呈流线
型，具有较大的口裂和锋利的牙齿，显
示其具备较强的捕食能力，可能捕食
小型无脊椎动物及其他水生动物。辐
鳍鱼类起源于古生代，并在随后的地
质历史过程中持续演化和分化。进入
中生代后，辐鳍鱼类经历快速辐射演

渐成为现代硬骨鱼类中的优势类群。
以张氏翼鳕为代表的罗平辐鳍鱼类，
展示了三叠纪早期鱼类生态策略多样

Pteronisculus changae
One of the Largest Basal Actinopterygian Predators in the 
Luoping Biota 
Pteronisculus changae reached approximately 30 cm in 
length and possessed a streamlined body, a large gape, 
and sharp teeth, indicating substantial predatory 
capability. It likely preyed on small invertebrates and other 
aquatic animals. Ray-finned fishes originated in the 
Paleozoic and continued to diversify throughout geological 
history. During the Mesozoic, they underwent a major 
evolutionary radiation, giving rise to a wide range of 
ecological forms and eventually becoming the dominant 
group of modern bony fishes. Represented by Pteronisculus 
changae, the ray-finned fishes of the Luoping Biota reveal 
the early diversification of fish ecological strategies during 
the Triassic and provide important insights into the 
evolutionary development of body structures 
characteristic of modern fishes.
