The Twin Mountains Formation is a dig site in Jurassic World Evolution. It was added with the Carnivore Dinosaur Pack.

InGen Database Description

The Twin Mountains Formation is situated in northern Texas, forming part of the Trinity Group of strata which spreads under 5 other states in the USA. The formation largely consists of sands, clays and conglomerates. Its name is derived from two small peaks near the city of Stephenville in Texas and the formation is around 50m thick in that area. It underlies parts of the Glen Rose Formation in which a famous set of dinosaur footprints were discovered.

The formation dates to the early Cretaceous period around 115 million years ago and has produced a number of indeterminate sauropod and theropod remains along with a partial skeleton of Acrocanthosaurus.
