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

酷東西

趣味知識

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

發現: 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
仍有爭議: 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
