Discovered the world's oldest fossil dinosaur fins

British scientists are the ones who discovered a whole new species of sword fins.

Shaping dinosaurs after being restored have a unique disc shaped bone protruding from the backbone. According to the British Museum of Natural History, they belong to a new genus dating back to 168 million years ago in the middle Jurassic period.

The complete fossil of a sword-shaped dinosaur was restored.

Earlier, only one of the most known dinosaurs dates from the late Jurassic period, making the newly discovered fossils the oldest evidence to be described and helping to increase their understanding. The evolution of this dinosaur group, Susannah Maidment, who led the research, said.

Maidment further explained: 'It is interesting that there may be more sword-finding dinosaurs to find in places that have not been excavated until now.'

The sword- dwelling dinosaur (Stegosaurus) was identified from the post-Jurassic period in western North America today. This 9m-long dinosaur is notable because it has two brains as big as an apple. One on the head and one on the main part of the tail. Fins usually have a habit of living in groups and have a sharp fin like blades on their backs.
