Elektorornis

名字的意思： “amber bird”1

吃：昆蟲早期鳥類白堊紀晚期

Elektorornis was a tiny bird that lived about 99 million years ago. It had a super long middle toe, much longer than its other toes. Scientists think it used that long toe to poke into tree bark and find tasty bugs to eat.1 2

酷東西

趣味知識

Elektorornis is the first bird species ever described from fossils found in Burmese amber.1

Its third toe was 20% longer than its whole foot bone (tarsometatarsus). No other known bird, alive or extinct, has such a long toe compared to its foot.2

This bird was smaller than a sparrow. It was an enantiornithine, a group of early birds that lived alongside dinosaurs.1 2

The only known fossil of Elektorornis is a partial right leg and some wing feathers, all preserved in a piece of amber.1 2

Elektorornis had big, curved claws and a long hallux (back toe) that helped it grip branches. It was an arboreal bird, meaning it lived in trees.2

Scientists think Elektorornis may have had a toothless beak to pry into wood, like a woodpecker, to reach insects.1

發現: Elektorornis chenguangi was named in 2019 by Lida Xing and colleagues. The fossil was found in Burmese amber at the Angbamo locality in Myanmar. The species name honors Chen Guang, a curator at the Hupoge Amber Museum.2 1
仍有爭議: Scientists are not sure exactly how Elektorornis used its extra-long middle toe. It might have been for probing tree bark for insects, or for better climbing, or both.2
