Transylvanosaurus
Transylvanosaurus was a plant-eating dinosaur that lived on an island in what is now Romania. It had a wide, flat head and walked on two legs, munching on tough plants with its beak. It was about the size of a large dog, but don't worry, it wouldn't hurt you!14

Transylvanosaurus had an unusually wide and flat skull, which is why its species name means 'flat head'.1
It lived on an island called Hațeg Island, where many dinosaurs were smaller than their mainland relatives, a phenomenon called insular dwarfism.1
The only known fossil is a partial skull, including the braincase and the bones of the top of the head.1
Scientists think it was closely related to Rhabdodon, a dinosaur from southern France, which suggests these dinosaurs could cross shallow seas.2
It lived during the Maastrichtian age, about 72 to 66 million years ago, right before the dinosaurs went extinct.4

Ibibazo bibazwa cyane kuri Transylvanosaurus
?How big was Transylvanosaurus?
It was about the size of a large dog or a man, roughly 2 metres long. This small size is due to insular dwarfism, because it lived on an island with limited food.3
?What did Transylvanosaurus eat?
It was a herbivore, meaning it ate plants. It used its beak to munch on tough plants that grew on its island home.3
?Could Transylvanosaurus swim?
Scientists think it might have been able to swim, because its closest relatives lived in France and it may have crossed shallow seas to reach its island. Most reptiles can swim from birth.3

Ibivugwa: Some people think Transylvanosaurus was a meat-eater because of its scary name.
Ukuri: Actually, it was a plant-eater, using its beak to crop plants, as shown by its teeth and skull shape.4
