Xinghaiornis

Naam beteken: “Xinghai bird, named after the Xinghai Museum in China”1

Xinghaiornis was a bird that lived about 125 million years ago. It had a long, toothless beak and probably poked in mud for food. It was a dinosaur, but a very bird-like one!2 1

Prettige feite

Xinghaiornis had a long, toothless beak, which is unusual for early birds.2

Its feet had a raised first toe, which may have helped it walk on soft mud.2

Scientists think it was a mud-prober, meaning it stuck its beak into mud to find food.2

This bird lived about 125 million years ago, during the Early Cretaceous period.1 2

Xinghaiornis is known from a single fossil found at Sihetun, Shangyuan Town in China.3
