Kryptodrakon Fun Facts

What did a Kryptodrakon look like?

Kryptodrakon dinosaurs were pterodactyloid pterosaurs that were carnivorous bird-like creatures. Their bones had been excavated from the China boundary. This discovery opened a lot of mysteries.

They had a very long beak which probably had teeth inside. There had no tail at the end of their body but, they had strong legs with which they could walk on land. They had both aerial and terrestrial environment adaptations. Their wings were well built and had a strong set of bones. According to the fossil, in their wings, the fourth metacarpal was relatively slender and elongated. The length of the fourth metacarpal was around 2.4 ft (72.2 cm). They had an amazing wingspan of around 4.8 ft (1.5 m). Though they were a species of pterosaurs and could fly, their bones were most probably not pneumatic.
