The fossil is roughly 120 million years of age and it is the left side from the animal#8217;s horse-like skull.
Mr Peaker added that what#8217;s most unusual concerning the fossil would be that the remains range from Cowleaze Chine, comprised of layers of clay and sandstone which rarely preserve dinosaur bones.
Emily Tabassi-Gill, from East Sussex, discovered the bones in Feb throughout a walk organised through the island#8217;s Dinosaur Isle museum.
He stated: #8220;We#8217;re really grateful to Emily on her donation.
Dinosaur Isle#8217;s community learning assistant, Alex Peaker, stated dinosaur skulls are #8220;incredibly rare#8221; since they#8217;re fragile and less inclined to become fossils than other bones.
Mom-of-two stated she was #8220;delighted#8221; her fossil would continue display and added: #8220;We#8217;ll certainly return to determine it.#8221;
