South America GiGanotosaurus

Until the 1950s, dinosaur fossils were rarely found in South
America since there was very little research carried out on this
continent. Since then, however, extensive fieldwork by teams
of paleontologists—and some chance finds by farmers—has
revealed dinosaur bones, eggs, and trackways at about 100 sites 8
across the continent. The South American dinosaurs show a close
resemblance to those found in North Africa, suggesting that the two Length: 43 ft (13 m)
continents were still connected during the mid-Cretaceous Period. Many Pronunciation: jig-an-o-toe-sore-us
dinosaur fossils have been found in the south, especially in Argentina. Meaning: “giant southern lizard”
Although they cover all periods of dinosaur existence, from the Late Triassic to
the Late Cretaceous, to date not many Jurassic fossils have been discovered. Mirischia
