Lisboasaurus
Sign in to saveLisboasaurus is a small (400 mm length) genus of Mesozoic crocodylomorph that lived in fresh water. It is known from fossilized tooth and jaw fragments of Late Jurassic and Early Cretaceous age. Two species have been described. In the past Lisboasaurus has been interpreted as an avialan, troodontid, or an anguimorph lizard. Both species are currently assigned to Crocodylomorpha, one is reassigned to the genus Lusitanisuchus.

==Discovery and naming== In the 1960s paleontologists From the Free University Berlin located new vertebrate fossil sites that included the lignite mines of Guimarota, near the town of Leiria, Portugal. These lignites are dated by Milner and Evans, 1991, between Bathonian (middle Jurassic) to Oxfordian (early Late Jurassic) age. Schwarz and Fechner, 2004, date them as Late Jurassic.
