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
