The Taman Formation is a geologic formation in Mexico. It preserves fossils dating back to the Jurassic period. It was deposited in a "oxic to anoxic (or anoxic-hypersaline), shallow marine environment" [1] The lithology predominantly consists of limestone and shale. [2]

The Gamuza Formation is a geologic formation in Mexico. It preserves fossils dating back to the Ediacaran period.
The Papalote Formation is a geologic formation in Mexico. It preserves fossils dating back to the Ediacaran period.
The La Caja Formation is a geologic formation in Mexico. It preserves fossils datiting from the Kimmeridgian to the lower Berriasian. La Caja Formation is widespread in northeastern and central Mexico and known for their abundant and diverse well-preserved ammonites. It was deposited in hemipelagic conditions, and predominantly consists of siliclastic sediments, including marl, with limestone. It is laterally equivalent to the La Casita Formation, which represent more proximal facies. The ichthyosaurs Ophthalmosaurus icenicus and Parrassaurus yacahuitztli, metriorhynchid Cricosaurus saltillensis and the giant pliosaur "Monster of Aramberri" are known from the formation.
The La Casita Formation is a geologic formation in Mexico. It preserves fossils dating back to the Kimmeridgian to lowermost Berriasian. It is laterally equivalent to the La Caja Formation and the Pimienta Formation. The ichthyosaurs Jabalisaurus and Acuetzpalin are known from the formation, as well as the metriorhynchid Dakosaurus and indeterminate pliosaurs.
The Pimienta Formation is a geologic formation in Mexico. It preserves fossils dating back to the Tithonian-Berriasian. The formation is considered laterally equivalent to the La Casita Formation. The Metriorhynchid Cricosaurus vignaudi is known from the formation.
The Tecomazuchil Formation is a geologic formation in Oaxaca, Mexico. It is made up of "a basal conglomerate 135 m thick and predominantly composed of quartz and metamorphic rock fragments, overlain by about 600 m of interbedded tan to red conglomerates, sandstones, and siltstones. The Tecomazuchil Formation overlies unconformably the Acatlán Complex and has been assigned a Middle Jurassic age, though it could represent at least part of the Oxfordian." Fossil Bennettitales have been found in the formation.
The Balumtun Sandstone is a geologic formation in Chiapas, Mexico. The formation is up to 760 metres thick, and consists of gray sandstone, that were deposited during the Upper Aquitanian stage of the Early Miocene.
The Mazantic Shale is a geologic formation in Chiapas, Mexico. It was deposited during the Early Miocene (Aquitanian). The formation comprises dark gray shales that were deposited in a marine environment. It preserves fossils, such as the turtle Allaeochelys liliae. Amber as been recovered from it.
The El Bosque Formation is a geologic formation in Mexico. It preserves fossils of plants, vertebrates, invertebrates and calcareous algae dating back to the Eocene period.
The Salagou Formation is a geologic formation in France. It preserves fossils dating back to the Permian period.
The Heather Formation is a geologic formation occurring in Norway and the United Kingdom. It preserves fossils from the Bathonian to Early Kimmeridgian stages of the Middle to Late Jurassic period and was deposited in a marine, anoxic palaeoenvironment.
