Sulcavis

Naam beteken: “groove bird”1

Sulcavis was a small, toothed bird that lived during the time of the dinosaurs. It had special grooves on its teeth, which no other bird had. This helped it eat hard foods like crunchy insects or seeds.1 2

Prettige feite

Sulcavis is the first bird ever found with decorated tooth enamel. Its teeth had grooves on the inside that made them stronger.1 2

It lived about 121 to 125 million years ago during the Early Cretaceous period.1

Sulcavis belonged to a group of ancient birds called enantiornitheans, which still had teeth and claws unlike modern birds.1

The fossil was found in the Yixian Formation, a famous rock layer in China that has preserved many feathered dinosaurs and early birds.1

Its name comes from Latin words meaning 'groove bird', because of the grooves on its teeth.1

Vir dino-kenners

Wetenskaplike naam: Sulcavis
Benoem deur: O'Connor et al. 20133
Groep: Vroeë voëls
Familie / klade: Bohaiornithidae3
Klassifikasie: Theropoda > Avialae3
Ouderdom van die rotse: 121 tot 113 miljoen jaar (Aptian)3
Rotsformasies: Jiufotang3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Sulcavis was named in 2013 by a team of scientists including Jingmai O'Connor. The fossil was found near Lamadong in Liaoning, China, and prepared by Maureen Walsh at the Natural History Museum of Los Angeles County.1
Steeds omstrede: Scientists are not sure exactly what Sulcavis ate, but the strong grooved teeth suggest it could handle harder food than other early birds.1 2
