Eoalulavis

Zita rinoreva: “dawn alula bird”1
Raidya: NyamaShiri dzekutangaCretaceous Yekutanga

Eoalulavis was a tiny bird that lived about 125 million years ago in what is now Spain. It was one of the earliest birds to have an alula, a special little wing feather that helps birds fly slowly and turn sharply.1

1

Eoalulavis was about the size of a European goldfinch, weighing only about 45 grams (1.6 ounces).1

2

Its wingspan, including feathers, was only about 26 centimeters (10 inches), similar to a modern kingfisher.1

3

The name Eoalulavis means 'dawn alula bird' because it is one of the earliest birds known to have an alula, or 'bastard wing'.1

4

Scientists found the remains of its last meal inside the fossil: concentrated pieces of crustacean shells.1

5

Eoalulavis had a very thin, spear-shaped breastbone, unlike the wide breastbones of most early birds.1

6

It likely flew in a bounding style, flapping hard then tucking its wings to dive, like modern songbirds and woodpeckers.1

7

The fossil was preserved with feathers and soft tissues because it was buried quickly in a lake with special conditions.1

?What did Eoalulavis eat?

It ate small crustaceans. Scientists found pieces of crustacean shells in its fossilized belly, its last meal.1

?How big was Eoalulavis?

It was tiny, about the size of a European goldfinch. It weighed about 45 grams and had a wingspan of about 26 centimeters.1

?Could Eoalulavis fly well?

Yes, it was a good flier. It had an alula for slow, sharp turns and likely used bounding flight, flapping hard then diving with wings folded, like modern songbirds.1
