新发现的微小食草恐龙Foskeia Pendonum(Foskeia plendonum)于1.2亿到1.25亿年前生活在西班牙北部。 A newly identified tiny herbivorous dinosaur, Foskeia pelendonum, lived about 120–125 million years ago in what is now northern Spain. 它大约是鸡的大小,属于Rhabdodontoformata组的兰尼新奇恐龙,并展示了独特的头骨和牙齿特征,表明在稠密的森林里有专门的喂养和灵活运动。 Roughly chicken-sized, it belonged to the Rhabdodontomorpha group of ornithischian dinosaurs and exhibits unique skull and tooth features suggesting specialized feeding and agile movement in dense forests. 至少有五人,包括经骨骼微结构确认的成年成人,从骨骼微结构中提供的生理证据表明,与鸟类或小型哺乳动物相似的快速生长速度。 Fossil evidence from at least five individuals, including a mature adult confirmed by bone microstructure, shows rapid growth rates akin to birds or small mammals. 生化分析将福斯凯亚与澳大利亚的Muttaburrasaurus紧密联系起来,扩大了欧洲Rhabdodontia clade,并支持植物食用恐龙构成自然进化组的想法。 Phylogenetic analysis links Foskeia closely to the Australian Muttaburrasaurus, expanding the European Rhabdodontia clade and supporting the idea that plant-eating dinosaurs form a natural evolutionary group. 这一发现有助于弥补化石记录中7 000万年的空白,并突出了研究小型碎裂化石以了解恐龙多样性和演变的重要性。 The discovery helps bridge a 70-million-year gap in the fossil record and highlights the importance of studying small, fragmentary fossils to understand dinosaur diversity and evolution.
