Holbotia was a small, feathered dinosaur that could fly, called a bird. It lived in Mongolia about 125 million years ago, during the Early Cretaceous. It had a special neck that could bend in a very flexible way, which was unusual for its kind.2

Mfundo zosangalatsa

1

Holbotia had a very flexible neck, with a bone shape that allowed it to bend its head in a way similar to modern darters, which are fish-eating birds.2

2

Its lower jaw had unusually widely spaced small teeth, which is different from many other early birds that had teeth packed closely together.2

3

Holbotia is the first articulated (still connected) skeleton of an enantiornithine bird ever found in Mongolia.2

4

The fossil was originally thought to be a pterosaur, a flying reptile, but scientists later realized it was a bird.2

5

Holbotia lived between 132 and 121 million years ago, during the Hauterivian to Barremian ages of the Early Cretaceous.3

6

It had a crest on the back of its lower leg bone, a feature not seen in other early birds of its group.2

Wothetsa nthano zabodza

Nthano: Some people think Holbotia was a pterosaur because its fossil was first misidentified.

Zoona: Holbotia was actually a bird, a type of feathered dinosaur, not a flying reptile. Scientists corrected the mistake after studying the bones.2

The fossil was unearthed in 1977 by palaeoentomologist Alexander G. Ponomarenko, but it was not officially named until 2015 by Zelenkov and Averianov. The species name honors Ponomarenko.12
Akukambiranabe
Scientists are still debating how Holbotia is related to other early birds, especially whether its tooth loss evolved separately from other bird groups.2
