The newly discovered dinosaur is believed to have been about the size of a Tyrannosaurus rex and has been named Spinosaurus mirabilis. The Latin word mirabilis translates roughly as "fantastic" in Swedish.
After several years of work, the researchers made the crucial fossil discoveries in 2022. Now the discoveries have been published in the journal Science, reports ABC News.
"We immediately understood that it was not just a Spinosaurus but a new species. People literally started crying," expedition leader Paul Sereno said in a statement.
The dinosaur was a carnivore but had interlocking rows of teeth, adapted to catch slippery fish, according to the researchers.
