1

Mirarce is the most complete enantiornithine bird ever found in North America.21

2

Its fossil was discovered in 1992 but was not officially named until 2018.1

3

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

4

It had a deeply keeled sternum (breastbone) and a narrow furcula (wishbone), features that improved its flight abilities.2

5

Mirarce lived during the Campanian age of the Late Cretaceous, about 76 to 74 million years ago.1

6

Its name combines Latin 'mirus' (wonderful) and the Greek messenger Arke, referring to its well-preserved flight-related features.1

The fossil was collected in 1992 by Howard Hutchison in Utah. It was studied and named by Jesse Atterholt and colleagues in 2018, who called it Mirarce eatoni in honor of paleontologist Jeffrey Eaton.1
ገና ዘከራኽር
Scientists are still debating how enantiornithine birds like Mirarce compare to modern birds in terms of flight abilities and evolutionary relationships.2
