A chicken-sized herbivorous dinosaur, Foskeia pelendonum, lived 120–125 million years ago in northern Spain and reveals new insights into dinosaur diversity and evolution.
A newly identified tiny herbivorous dinosaur, Foskeia pelendonum, lived about 120–125 million years ago in what is now northern Spain.
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.
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.
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.
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.
