ደስ ዝብሉ ሓቅታት

Keresdrakon had a unique blunt ridge on the top of its lower jaw that no other pterosaur has.1

All the Keresdrakon fossils found so far are from late juveniles or sub-adults, not fully grown adults.1

It lived in a Cretaceous desert with interdunal wetlands, where water and food were scarce.1

Keresdrakon is one of the first pterosaurs found living together with another pterosaur species, showing they shared the same habitat.1

Its long, flat beak was good for picking up small or dead animals, similar to how a marabou stork feeds today.1

The name Keresdrakon means 'ghost dragon' in Greek, inspired by its mysterious desert home.1

ብዛዕባ Keresdrakon ብብዝሒ ዝሕተቱ ሕቶታት

?What did Keresdrakon eat?

It was probably an opportunistic predator or scavenger, eating small animals, eggs, or carcasses, similar to a marabou stork today.1

?When did Keresdrakon live?

It lived during the Early Cretaceous, about 125 to 100.5 million years ago, though the exact age of its rock formation is debated.3

?Was Keresdrakon a dinosaur?

No, it was a pterosaur, a flying reptile that is not a dinosaur.3

?Did Keresdrakon live with other pterosaurs?

Yes, it lived alongside another pterosaur called Caiuajara, and this is the first direct evidence of two pterosaur species living together.3 1
