A surprising fossil

Kassia and Helmi looked curiously at the dinosaur fossil that Einar's slaves had found.

"What kind of dinosaur is this Einar?"

Helmi asked as she stroked the fossil's elongated skull with her hand.

Einar crouched down and began to explain how little he remembered about the pterodactyl.

"It should be a flying dinosaur which was a carnivore, although I don't remember many things about it.

But I can say that it was an oviparous so that its reproduction was through eggs. Because of the size of its body, I can say that it was an adult specimen.

I can infer that it was a pterodactyl due to the size, although it appears to be very large measuring about one and a half meters in size.

What was the average size of these dinosaurs, there is also the elongated shape of the skull and this strange fin in the middle of the skull.
