About Lourinhanosaurus:

One of the few large theropods to be discovered in Portugal, Lourinhanosaurus (named after that country's Lourinha Formation) has proven difficult to classify: paleontologists can't decide if it was most closely related to Allosaurus, Sinraptor or the equally obscure Megalosaurus. This late Jurassic predator is noteworthy for two reasons: first, scientists have identified gastroliths among its fossilized stomach contents, which Lourinhanosaurus clearly swallowed on purpose rather than ingesting by accident when eating herbivorous dinosaurs. And second, a clutch of about 100 Lourinhanosaurus eggs, some containing fossilized embryos, have been found close to the original excavation site.
