sentences:  So far, this unnamed giant velociraptorine is known only from isolated teeth found on the Isle of Wight, England.The teeth belong to an animal the size of dromaeosaurines of the genus "Utahraptor", but they appear to belong to a velociraptorine, judging by the shape of the teeth and the anatomy of their serrations.In 2007 paleontologists studied front limb bones of "Velociraptor" and discovered small bumps on the surface, known as quill knobs.
