Limenavis is known only from a few broken wing bones, but these bones show it was more advanced than older birds like Ichthyornis.3

Its name means 'bird of the threshold' because it lived right at the doorstep of modern birds.1

Scientists have debated whether Limenavis was closer to modern birds or to more primitive ones, and different studies have placed it in different groups.1

Some scientists think Limenavis might be related to the ancestors of tinamous or rheas, which are birds that still live in South America today.1

Limenavis lived in what is now Patagonia, Argentina, during the Late Cretaceous period, about 70 million years ago.1
