[D] Lisboasaurus estesi [ncG]
Not considered dinosaur
Unnamed Unit, Estremadura, Portugal
As-yet-undescribed material of Lisboasaurus from Las Hoyas in Spain indicates it is not a dinosaur but some kind of mesosuchian crocodylian. Lisboasaurus was originally described in 1973 as a lacertilian and later, in 1991, British paleontologists Angela C. Milner and Susan Evans redescribed it as a small maniraptoran. (Jurassic Late Oxfordian) More recent work suggests that Lisboasaurus is actually a crocodylomorph .
