The Twin Mountains Formation, also known as the Twin Mountain Formation, is a sedimentary rock formation, within the Trinity Group, found in Texas of the United States of America. It is a terrestrial formation of Aptian age, and is notable for its dinosaur fossils. Dinosaurs from this formation include the large theropod Acrocanthosaurus, the sauropod Sauroposeidon, as well as the ornithopods Tenontosaurus and Convolosaurus. It is the lowermost unit of the lower Cretaceous, lying unconformably on Carboniferous strata. It is overlain by the Glen Rose Formation. It is the lateral equivalent of the lower part of the Antlers Formation.
Dongbeititan is a genus of sauropod dinosaur from the Early Cretaceous-age Yixian Formation of Beipiao, Liaoning, China. It is based on holotype DNHM D2867, a partial postcranial skeleton including bones from the limbs, shoulder and pelvic girdles, and vertebrae. Its describers suggested it was as a basal titanosauriform, not as derived as Gobititan or Jiutaisaurus, but more derived than Euhelopus, Fusuisaurus, and Huanghetitan. The type species is D. dongi, and it is the first named sauropod from the Yixian Formation, which is part of the well-known Jehol Group. The genus name refers to the region Dongbei and to Greek titan, "giant". The specific name honours the Chinese paleontologist Dong Zhiming. Like other sauropods, Dongbeititan would have been a large quadrupedal herbivore.
The Alcobaça Formation is a geological formation in Portugal. It dates back to the Oxfordian stage of the Late Jurassic. It is an important source of information on the diversity of Late Jurassic mammals. Many of the fossils were collected from the now disused and flooded Camadas de Guimarota coal mine.

The White Limestone Formation is a Bathonian geologic formation in the United Kingdom, dating to the Middle Jurassic, 168.3 to 166.1 million years ago. Fossil sauropod tracks have been reported from the formation. It is the lateral equivalent of the Blisworth Limestone. It predominantly consists of grey-yellow limestone, typically wackestone and packstone with subordinate ooidal grainstone. The dinosaur Proceratosaurus is known from the formation.
