The new dino's unique name, Zby atlanticus, comes from paleontologist Georges Zbyszewski, who hunted for dino remains for many years in Portugal. "Zby" honors him. The "atlanticus" part is due to the present locality of Paimogo, which has a scenic view of the Atlantic Ocean.

"We thought for a long time that it was a species that was known in Spain, the turiasaurus, but in fact the anatomical differences we began to notice were sufficient for us to reclassify it, not just as a new species but as a new genus for science", Mateus told The Portugal News Online.
He explained that "various different crests on the bones of its limbs" helped to distinguish Zby atlanticus from other previously documented dinos.
The second new big dinosaur, now added to the record books, is Leinkupal laticauda. It was found in what's now Argentina and has at least a couple of claims to fame.
