Mount Bonnell, also known as Covert Park, is a prominent point alongside the Lake Austin portion of the Colorado River in Austin, Texas. It has been a popular tourist destination since the 1850s. The mount provides a vista for viewing the city of Austin, Lake Austin, and the surrounding hills. It was designated a Recorded Texas Historic Landmark in 1969, bearing Marker number 6473, and was listed on the National Register of Historic Places in 2015.
Weald Clay or the Weald Clay Formation is a Lower Cretaceous sedimentary rock unit underlying areas of South East England, between the North and South Downs, in an area called the Weald Basin. It is the uppermost unit of the Wealden Group of rocks within the Weald Basin, and the upper portion of the unit is equivalent in age to the exposed portion of the Wessex Formation on the Isle of Wight. It predominantly consists of thinly bedded mudstone. The un-weathered form is blue/grey, and the yellow/orange is the weathered form, it is used in brickmaking.
The Glen Rose Formation is a shallow marine to shoreline geological formation from the lower Cretaceous period exposed over a large area from South Central to North Central Texas. The formation is most widely known for the dinosaur footprints and trackways found in the Dinosaur Valley State Park near the town of Glen Rose, Texas, southwest of Fort Worth and at other localities in Central Texas.
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 Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe. It was deposited during the Middle Jurassic. The Inferior Oolite Group as more recently defined is a Jurassic lithostratigraphic group in southern and eastern England. It has been variously known in the past as the Under Oolite, the Inferior Oolite, the Inferior Oolite Series and the Redbourne Group.
The Eagle Sandstone, originally the Eagle Formation, is a geological formation in Montana whose strata date back to the Late Cretaceous. It is a light to brownish gray to pale yellow-orange, fine-grained sandstone. It contains areas of crossbedding and local shale members. It contains large sandy calcareous concretions. Its thickness varies from 100 to 350 feet due to the lens nature of the individual sandstone layers and local interbedded sandy shale layers.
The Lianmuqin Formation, also transcribed as Lianmugin Formation, and Lianmuxin Formation, is an Early Cretaceous geologic formation composed of "interbedded red green and yellow variegated mudstones and siltstones". Dinosaur remains have been recovered from it.
The Patuxent Formation is a Cretaceous geologic formation of the Atlantic coastal plain.
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 Jiaguan Formation is a Lower Cretaceous geologic formation in China. Its lithology is described as consisting of "alternating thick purple red sandstone layers and thin purple red mudstone and siltstone layers, and bottom layers of thick conglomerate" Fossil ornithopod tracks have been reported from the formation.
The Geoncheonri Formation is an Early Cretaceous (Aptian-Albian) geologic formation of the Hayang Group in the Gyeongsang Basin of southeast South Korea. Fossil ornithopod tracks, as well as fossils of Kirgizemys have been reported from the lacustrine siltstones and mudstones of the formation.
The Akaiwa Formation is an Early Cretaceous (Hauterivian-Barremian) geologic formation in central Honshu, Japan. Indeterminate ornithischian fossils are known from the formation. Fossil ornithopod tracks have been reported from the formation. As well as the turtle Kappachelys
The Tongfosi Formation is a Late Cretaceous (Cenomanian) geologic formation of the Yanji Group in China. Fossil ornithopod tracks of iguanodontids and theropods have been reported from the fluvial sandstones of the formation.
The Tochikubo Formation is a Jurassic geologic formation in northern Honshu, Japan, dating to the Oxfordian stage of the Late Jurassic. Fossil ornithopod tracks have been reported from the formation. As well as the Bennettitalean Kimuriella.
The Trinity Group is a group in the Lower Cretaceous lithostratigraphy of Texas, Arkansas, Mississippi, Louisiana and Oklahoma. It is named for the Trinity River of Texas.
The Mesa Rica Sandstone is a geologic formation in Oklahoma and New Mexico. It preserves fossils dating back to the Cretaceous period.
The Del Rio Clay is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Hammett Shale is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Edwards Group is a geologic group in Texas. It preserves fossils dating back to the Cretaceous period.
