Avimaia was a small bird that lived about 120 million years ago. It is special because scientists found an egg still inside its body. This helps us learn how ancient birds had babies.2 1

Ebyewuunyisa

Avimaia is the only fossil bird ever found with an unlaid egg still inside its body.1

The eggshell of Avimaia was very thin and had multiple layers. Scientists think this happened because the egg stayed too long inside the mother.1

Avimaia's leg bones contain medullary bone. This is a special tissue that only female birds make when they are ready to lay eggs.1

The egg of Avimaia was flattened and measured about 5.2 square centimeters.1

Avimaia lived during the Early Cretaceous period, about 121 to 113 million years ago.2

The name Avimaia means 'bird mother' in Latin, because the fossil is a female with an egg.1

Ekifaananyi kya Avimaia ekyakolebwa AI, nga kiraga engeri gye yayinza okuba ng'afaanana, ekyakolebwa kompyuta okusinziira ku ebyo bannassaayansi bye bamanyi. Kuteebereza: ekisolo ekyennyini kiyinza okuba nga kyali kifaanana bulala, era tewali amanyi langi zaakyo ez'amazima.

Kikyakubaganyizibwako ebirowoozo: Scientists are not sure why the eggshell of Avimaia was so thin and had multiple layers. It might have been a health problem or a normal part of its reproduction.1
