English: Eoneophron is a caenagnathid theropod dinosaur from the Late Cretaceous Hell Creek Formation of North America. Caenagnathids can be differentiated from other oviraptorosaurs by their distinct jaws, which tended to be relatively long and shallow, suggesting that the bite was not as powerful. Caenagnathids also tended to be more lightly built. They had slender arms and long, gracile legs, although they didn't seem to be especially cursorial. Eoneophron's body mass is estimated at approximately 78 kg.
