Datos curiosos
Its fossil was discovered in 1992 but was not officially named until 2018.1
Mirarce had quill knobs on its ulna bone, which are bumps that help anchor flight feathers. This is the first time such knobs have been found in enantiornithine birds.21
It had a deeply keeled sternum (breastbone) and a narrow furcula (wishbone), features that improved its flight abilities.2
Mirarce lived during the Campanian age of the Late Cretaceous, about 76 to 74 million years ago.1
Its name combines Latin 'mirus' (wonderful) and the Greek messenger Arke, referring to its well-preserved flight-related features.1
