The first trailer is set on Isla Muerta, which belongs to The Muertes Archipelago (also known as The Five Deaths - Las Cinco Muertes in Spanish- that is a chain of five islands 200 miles southwest of Costa Rica). Because the island is surrounded by mist and nearly impossible to get on, even with a boat, the island has had few interactions with humans throughout its history. Like Isla Sorna, Isla Muerta is a volcanic island. The island is lined with enormous mountains and steep volcanic cliffs. Overtime, the island became covered in coniferous forests. Like with Isla Sorna, the dinosaurs on Isla Muerta roam free and there are even fewer human installations on the island for them to interact with than previous islands.
Also, in the trailer you can meet 7 different species of dinosaurs that are roaming in Isla Matanceros!!!
