Guaratiba Group The Guaratiba Group (Portuguese: "Grupo Guaratiba" ) is a geological group of the Santos Basin offshore of the Brazilian states of Rio de Janeiro, São Paulo, Paraná and Santa Catarina. The group forms the pre-salt layer in the petroleum-rich basin and hosts the biggest oil fields of Brazil, as Lula, Júpiter and many more. The group contains, depending on the definition, three to four formations and dates to the Early Cretaceous period; Hauterivian to Early Aptian epochs. The total thickness of the group, representing the first phase of sedimentation after the break-up of Gondwana in the Santos Basin, is estimated at 4200 m .

Marginocephalia Marginocephalia (/mär′jə-nō-sə-făl′ē-ən/ Latin: margin-head) is a clade of ornithischian dinosaurs that is characterized by a bony shelf or margin at the back of the skull. These fringes were likely used for display. There are two clades included in Marginocephalia: the thick-skulled Pachycephalosauria and the horned Ceratopsia. All members of Marginocephalia were herbivores. They basally used gastroliths to aid in digestion of tough plant matter until they convergently evolved tooth batteries in Neoceratopsia (or "new Ceratopsia") and Pachycephalosauria. Marginocephalia first evolved in the Jurassic Period and became more common in the Cretaceous. They are basally small facultative quadrupeds while derived members of the group are large obligate quadrupeds. Primitive marginocephalians are found in Asia, but the group migrated upwards into North America

Carusioidea Carusioidea is a clade (evolutionary grouping) of lizards that includes the family Xenosauridae (knob-scaled lizards) from Central America and the extinct genus "Carusia" from the Late Cretaceous of Mongolia. It was named in 1998 after a sister-group relationship was found between "Carusia" and Xenosauridae. Phylogenetic analysis indicates that Carusioidea is the most basal clade within Anguimorpha. Features that help define Carusioidea include closely spaced orbits or eye sockets separated by fused frontal bones, a connection between the jugal and squamosal bones below the supratemporal arch, and a covering of bony osteoderms over the skull roof. Below is a cladogram showing the phylogenetic relationships of carusioids from Gao and Norell (1998):

La Negra Formation La Negra Formation (Spanish: "Formación La Negra" ) is a geologic formation of Jurassic age, composed chiefly of volcanic and volcaniclastic rocks, located in the Coast Range of northern Chile. The formation originated in marine and continental (terrestrial) conditions, and bears evidence of submarine volcanism as well as large explosive eruptions. The volcanism of La Negra Formation is thought to have lasted for about five million years.

Cherry Canyon Formation The Cherry Canyon Formation is a Permian geologic unit in Guadalupe Mountains National Park. The formation contains fan sandstones that were deposited under ancient seawater during the Middle Permian. These rocks contain abundant fish fossils like sharks' teeth preserved within small phosphatic nodules.

Shinarump Conglomerate The early Late Triassic conglomerate called the Shinarump Conglomerate, formally the "Shinarump Member of the Chinle Formation", is a highly resistant coarse-grained sandstone and pebble conglomerate, sometimes forming a caprock because of its hardness, cementation, and erosion resistance. The Shinarump is found throughout the Colorado Plateau with significant exposures as the canyon rimrock in the vicinity of Canyon De Chelly National Monument, at the north-northeast of the Defiance Plateau/Defiance Uplift. At Canyon De Chelly the Shinarump Conglomerate was laid down upon De Chelly Sandstone-(280 Ma, an erosion unconformity of 50 my), in a region at the west foothill region of the mostly north-south trending Chuska Mountains of northeast Arizona – northwest New Mexico.

Iguanodontia Iguanodontia (or iguanodonts) is a clade of herbivorous dinosaurs that lived from the Middle Jurassic to Late Cretaceous. Some members include "Camptosaurus", "Callovosaurus", "Iguanodon", "Tenontosaurus", and the hadrosaurids or "duck-billed dinosaurs". Iguanodontians were one of the first groups of dinosaurs to be found. They are among the best known of the dinosaurs, and were among the most diverse and widespread herbivorous dinosaur groups of the Cretaceous period. Derived iguanodontians (such as "Muttaburrasaurus" and many ankylopollexians) were generally large animals, and some (such as "Shantungosaurus", which measured up to 50 ft (15 m) in length and weighed up to 8 tons) equaled the largest carnivorous dinosaurs in size.

Coloradisaurus Coloradisaurus (meaning "Colorados [from Los Colorados Formation] lizard") is a genus of massospondylid sauropodomorph dinosaur. It lived during the Late Triassic period (Norian to Rhaetian stages) in what is now La Rioja Province, Argentina. It is known from the holotype PVL 5904, nearly complete skull. It was discovered and collected from the upper section of the Los Colorados Formation. Originally named "Coloradia" by Jose F. Bonaparte in 1978, this name had already been assigned to a moth, and so the animal was renamed. The genus was first named by David Lambert in 1983 and the type species is "Coloradisaurus brevis". It may in fact be an adult specimen of "Mussaurus". Cladistic analyses by Yates (2007), Yates "et al." (2010, 2011) and Novas "et al." (2011) found that "Coloradisaurus" is basal to the "Glacialisaurus"-"Lufengosaurus" clade within Massospondylidae.

Titanosaur Titanosaurs (members of the group Titanosauria) were a diverse group of sauropod dinosaurs, which included "Saltasaurus" and "Isisaurus". When the extinction event at the end of the Cretaceous period occurred, they were the last surviving group of long-necked dinosaurs. The group includes some of the heaviest creatures ever to walk the earth, such as "Argentinosaurus" and "Puertasaurus", which are estimated to have weighed up to 90 t . The group's name refers to the much earlier discovery "Titanosaurus", a now dubious genus named for the mythological Titans of Ancient Greece. Together with the brachiosaurids and relatives, titanosaurs make up the larger clade Titanosauriformes.
