Formations

Overview[]

Formations are assemblages of rocks that are deposited across geological time and location that help differentiate and assign animals to specific ecological regions of the world. Formations vary wildly due to a number of factors, ranging from their environment, terrain, and inhabitants (fauna and flora).

Prehistoric Kingdom has a variety of formations available to the player. Each dig site represents a diverse ecosystem of animals that time has left behind, but can be dug up and resurrected in your parks. Each dig site is accessible through the Excavations menu. In the menu, you can unlock each dig site via ingame payment and a required star rating. You can see a preview of the animals available in the formation by hovering over its icon.

After unlocking a formation, you can purchase any animal from the region. Subsequently, you can purchase additional genetic skins which become cheaper the more you acquire. Some animals that have alternate species, such as Tyrannosaurus, Edmontosaurus, and Torvosaurus, are found across multiple locations, while others (like Triceratops and Camarasaurus) have all of their species located at the same formation.

Huincul Formation	Late Cretaceous	An arid sandstone formation within the center of Argentina, the Huincul Formation's dry tropical fields were the cradle for titans.	Argentinosaurus huinculensis
Luján Formation	Pleistocene	Home to the famous saber-toothed tigers of South America, the swampy flood plains of the Luján Formation was a paradise for mammals.	Smilodon populator

European Dig sites[]

Formation	Epoch	Description	Animals
Altmühltal Formation (also known as Solnhofen Limestone)	Late Jurassic	The Altmühltal Formation is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies. The most familiar fossils of the Altmühltal Formation include the early bird Archaeopteryx preserved in such detail that they are among the most famous and most beautiful fossils in the world.	Archaeopteryx lithographica
Charmouth Mudstone Formation	Early Jurassic	A marine deposit where dinosaurs are quite rare, the Charmouth Mudstone Formation played an important role in early paleontological history, being frequented by renowned fossil collectors including Mary Anning.	Scelidosaurus harrisonii
Lourinhã Formation	Late Jurassic	Known for its faunal overlap with the Morrison and Tendaguru Formations, the coastal Lourinhã Formation is very rich in fossils, footprints, and eggs.	Torvosaurus gurneyi
Löwenstein Formation	Late Triassic	TBA	Plateosaurus gracilis
Tokod Formation	Pleistocene	(WIP)	Coelodonta antiquitatis, Mammuthus primigenius, Megaloceros giganteus, Panthera spelaea, Ursus spelaeus
Trossingen Formation	Late Triassic	TBA	Plateosaurus trossingensis
Wessex Formation	Early Cretaceous	A historically significant formation, having been the site where the original dinosaurs were discovered, the rainy Wessex Formation was once a pristine Mediterranean scrubland.	Iguanodon bernissartensis

African Dig sites[]

Formation	Epoch	Description	Animals

Formation	Epoch	Description	Animals
Eumeralla Formation	Early Cretaceous	Formed during the break up of Australia and Antartica, the Eumeralla Formation has revealed important insights into this polar world.	Leallynasaura amigraphica
Mackunda Formation	Early Cretaceous	The Mackunda Formation represents one of the times the Eromanga Sea filled a large portion of inland Australia; the sea created excellent conditions for both the preservation of skeletons and the creation of opals.	Muttaburrasaurus langdoni

Removed Dig Sites[]

Winton Formation[]

Upon release of Update 9, Muttaburrasaurus langdoni was found in the Winton Formation despite having no described fossils from there. The subsequent Hotfix (EA 1.6.16) replaced the Winton Formation with the accurate Mackunda Formation.

It is possible that the Winton Formation could return to the game if an animal described from the formation is added to Prehistoric Kingdom.

Mammoth Steppe Formations (Vilyui River and Yamal Peninsula)[]

The release of Update 10 brought the removal of the Vilyui River and Yamal Peninsula dig sites; this was most likely due to the fact that these locations were not true formations, rather, they were locations where specimens had been revealed from the permafrost.

The ani mals that were previously found in these locations were moved to the newly added Tokod Formation, which represents a fuller picture of the Mammoth Steppe biota.

Trivia[]

Prior to Update 5, animals were unlocked with science points, a removed currency. Henceforth, both the formation and animals have been purchasable with normal in-game currency.
