Holbotia

Naam beteken: “named after the Holbot locality where it was found”1

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

Prettige feite

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

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

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

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

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

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

KI-prent van Holbotia — 'n KI-prent van hoe Holbotia dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Mite-breker

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

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

Vir dino-kenners

Wetenskaplike naam: Holbotia
Benoem deur: Zelenkov and Averianov 20154
Groep: Vroeë voëls
Familie / klade: Enantiornithes4
Klassifikasie: Theropoda > Avialae4
Ouderdom van die rotse: 133 tot 121 miljoen jaar (Hauterivian / Barremian)4
Rotsformasies: Andaikhudag4
Lande: Mongolië4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: 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.1 2
Steeds omstrede: Scientists are still debating how Holbotia is related to other early birds, especially whether its tooth loss evolved separately from other bird groups.2
