Phyllodon was a genus of small ornithischian dinosaur from the Kimmeridgian-aged Upper Jurassic Camadas de Guimarota Formation of Leiria, Portugal and possibly also the Bathonian-aged Chipping Norton Limestone of England. It may have been closely related to contemporaneous dinosaurs in North America.
The Kayenta Formation is a geological formation in the Glen Canyon Group that is spread across the Colorado Plateau province of the United States, including northern Arizona, northwest Colorado, Nevada, and Utah. Traditionally has been suggested as Sinemurian-Pliensbachian, but more recent dating of detrital zircons has yielded a depositional age of 183.7 ± 2.7 Ma, thus a Pliensbachian-Toarcian age is more likely. A previous depth work recovered a solid "Carixian" age from measurements done in the Tenney Canyon. More recent works have provided varied datations for the layers, with samples from Colorado and Arizona suggesting 197.0±1.5-195.2±5.5 Ma, while the topmost section is likely Toarcian or close in age, maybe even recovering terrestrial deposits coeval with the Toarcian Oceanic Anoxic Event. This last age asignation also correlated the Toarcian Vulcanism on the west Cordilleran Magmatic Arc, as the number of grains from this event correlate with the silt content in the sandstones of the upper layers.
The Lufeng Formation is a Lower Jurassic sedimentary rock formation found in Yunnan, China. It has two units: the lower Dull Purplish Beds/Shawan Member are of Hettangian age, and Dark Red Beds/Zhangjia'ao Member are of Sinemurian age. It is known for its fossils of early dinosaurs. The Dull Purplish Beds have yielded the possible therizinosaur Eshanosaurus, the possible theropod Lukousaurus, and the "prosauropods" "Gyposaurus" sinensis, Lufengosaurus, Jingshanosaurus, and Yunnanosaurus. Dinosaurs discovered in the Dark Red Beds include the theropod Sinosaurus triassicus, the "prosauropods" "Gyposaurus", Lufengosaurus, and Yunnanosaurus, indeterminate remains of sauropods, and the early armored dinosaurs Bienosaurus and Tatisaurus.
The Argana Group is a Permian to Triassic geological group in the western High Atlas northeast of Agadir, Morocco. Sometimes known as the Argana Formation, it contains eight geological members often divided into three formations. They include the Late Permian Ikakern Formation, the Early Triassic to Carnian Timezgadiouine Formation (T3-T5), and the Late Triassic Bigoudine Formation (T6-T8). Ornithischian tracks are geographically located in Marrakesh province. Indeterminate theropod remains and tracks are geographically located in Marrakesh province.
The Portland Formation is a geological formation in Connecticut and Massachusetts in the northeastern United States. It dates back to the Early Jurassic period. The formation consists mainly of sandstone laid down by a series of lakes and the floodplain of a river. The sedimentary rock layers representing the entire Portland Formation are over 4 kilometres (2.5 mi) thick and were formed over about 4 million years of time, from the Hettangian age to the late Hettangian and Sinemurian ages.
The Alcobaça Formation, previously known as the Guimarota Formation and also known as the Consolação Unit, is a geological formation in Portugal. It dates back to the Kimmeridgian 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 Penglaizhen Formation, is a geological formation in Sichuan, China. It was formerly thought to be Late Jurassic in age. However, the underlying Suining Formation has been dated to the Mid Cretaceous, so the formation must be this age or later However a subsequent study suggested that the dates for the formation had been altered by geologic processes, and there dating the Suining Formation to the around the Jurassic Cretaceous boundary about 145 Ma, which means that Penglaizhen Formation is likely Early Cretaceous in age. Dinosaur remains are among the fossils that have been recovered from the formation.
The Höganäs Formation is a Late Triassic to Early Jurassic geologic formation in Skåne, Sweden. The formation is mostly known for its incredible flora collection from the Bjuv member, composed of over 110 species, and also includes several vertebrate remains, such as fishes, amphibians and dinosaur tracks & remains, although none have yet been referred to a specific genus.
The Saltwick Formation is a Middle Jurassic geologic formation in Yorkshire and the western North Sea. It is primarily Aalenian in age. Fossil footprints, assigned to the tetrapod ichnogenus Characichnos, as well as stegosaur tracks have been reported from the formation. An indeterminate sauropod, nicknamed Alan, has also been reported from the formation.
The Towaco Formation is a mapped bedrock unit in New Jersey. It is named for the unincorporated village of Towaco, which is near the place its type section was described by paleontologist Paul E. Olsen.
The Mecsek Coal Formation is a Jurassic geologic formation in Hungary. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Feltville Formation is a mapped bedrock unit primarily in New Jersey, with one known outlier in Pennsylvania and another one in New York. It is named for the Deserted Village of Feltville in Watchung Reservation, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen.
The East Berlin Formation is an Early Jurassic geological formation in New England, United States. Dinosaur footprints and trackways are abundant in this formation. These tracks include Eubrontes, Anchisauripus, and Anomoepus. Several museums, parks, and tourist attractions are based around the East Berlin Formation's dinosaur tracks, including Dinosaur State Park in Rocky Hill, Connecticut and Powder Hill Dinosaur Park in Middlefield, Connecticut.
The Boonton Formation is a mapped bedrock unit in New Jersey, formerly divided between the Boonton and Whitehall beds of the defunct Brunswick Formation. It is named for the town of Boonton, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen.
The Ansbachersandstein is a Late Triassic (Carnian) geologic formation in Germany. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Abu Agag Formation is a Turonian geologic formation in Egypt and Sudan. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Kiyosu-e Formation is a Middle Jurassic (Callovian) to Early Cretaceous (Berriasian) geologic formation of the Toyonishi Group in Yamaguchi Prefecture, Japan. Fossil ornithopod tracks have been reported from the formation.
The Bull Run Formation is a Late Triassic (Norian) stratigraphic unit in the eastern United States. Fossil fish bones and scales have been found in outcrops of the formation's Groveton Member in Manassas National Battlefield Park. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Kcskehát Limestone is a Jurassic geologic formation in Hungary. Indeterminate fossil Sauropod tracks have been reported from the formation. It is abundant on Illite and very little Kaolinite that indicates a change from the humid-subtropical climate of the Mecsek Coal Formation to the monsoon-like semi-arid climate of the Pliensbachian formations. The dominance of illite indicates a relatively fast erosion of the source area and a moderate input of terrigenous clastics relative to the underlying formations.
