The fossils of Helicoprion, Dimetrodon and other extinct creatures of the Permian can now be excavated and explored by virtual paleontologists. Thus, the primeval world of the browser game grows by five creatures. These are the new additions at a glance:

• Orthacanthus - a freshwater shark about three meters long with highly specialized fins. In the absence of food, he became a cannibal.
• Dinogorgon - carnivore with saber-tooth-like canines, could probably run fast and is considered a relative of mammals.
• Moschops - A herbivorous terrestrial vertebrate with a thick skullcap. It probably used it to head-butt rivals like sheep and goats do today.
• Helicoprion - A cartilaginous fish probably related to modern sea cats. Its lower jaw consists of a spiral row of teeth - almost like a circular saw.
• Dimetrodon - Reptile-like predator that was one of the greatest hunters of its time. Is nevertheless related to mammals. Most striking feature: its huge dorsal sail.

Once players have collected enough fossils for one of the animals, they can research it and then bring it to life. The prehistoric animals bred in this way can be housed in the enclosures of My Free Zoo or in the specially created prehistoric enclosures for water or land animals.
