Lisboasaurus is not a dinosaur — it was originally described as a lizard-like reptile (a possible lacertilian or early lizard) from the Late Jurassic of Portugal. It is generally considered a nomen dubium because the fragmentary dental material on which it is based cannot be reliably diagnosed. Some specimens once referred to it have been reassigned to other taxa. It is sometimes mentioned in dinosaur-era fauna lists due to its age and locality, but it is not a member of Dinosauria.
