The Tujingzi Formation is a geological formation in Hebei, China whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. [1]
Yaverlandia is a genus of maniraptoran dinosaur. Known from a partial fossil skull found in Lower Cretaceous strata of the Wessex Formation on the Isle of Wight. it was described as the earliest known member of the pachycephalosaurid family, but research by Darren Naish shows it to have actually been a theropod, seemingly a maniraptoran. The type species is Y. bitholus.
The Twin Mountains Formation, also known as the Twin Mak 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.
The Bluff Dale Sandstone is a geological formation in Texas whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Paluxy Formation is a geological formation found in Texas, Louisiana, Arkansas, Mississippi and Oklahoma, whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Calcaire à Spatangues is a geological formation in the Paris basin of northern central France whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Grès et sables piquetés is a geological formation in Haute Marne and Meuse Departments, France, that dates back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Argiles Ostréennes is a geological formation in northern central France whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Bauxite of Cornet is a geological formation in Romania whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. It exists as karstic sediments infilling fissures and caves in limestone.
The Shestakovskaya Svita is a geological formation in Mongolia and eastern Russia whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Khooldzin Svita is a geological formation in Mongolia whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Lura Formation is a geological formation in western China, which outcrops in Tibet, whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Kezilesu Group is a geological formation in China whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Dashuigou Formation is a geological formation in Inner Mongolia, north China, whose strata date back to the Early Cretaceous period.
The Xinpongnaobao Formation is a geological formation in Inner Mongolia, China whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Yijinholuo Formation is a geological formation in Inner Mongolia, China whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The El Picacho Formation is a geological formation in Texas, United States, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. The paleosols found here are rich in clay, calcite, and rhizoliths which show that during the Cretaceous period, this fossil formation, just like the neighboring Javelina Formation and Aguja Formation, was a fluvial flood plain.

The Turginskaya Svita is an Early Cretaceous period geologic formation located in Russia. Dinosaur remains were recovered from it as early as 1915, including partial theropod remains.
