Echinaria is an extinct genus of brachiopods which lived during the Upper Carboniferous and Lower Permian periods. Its fossils have been found in Eurasia, North America and northern South America. [1]
Like other echinoconchids, Echinaria had thin, recumbent spines arranged in concentric bands on both valves, as well as a corpus with a planoconvex profile and deep cavity. Members of this genus had cardinal ridges and an elongated outline which widened anteriorly. [1] Echinaria are medium to large-sized echinoconchids, and while notably larger than Echinoconchus , many similarities are observed between the two genera and they are placed in the same subfamily. [2]
Leighton & Maples (2002) conducted multiple phylogenetic analyses which are strongly in agreement that the four subfamilies Buxtoniinae, Echinoconchinae, Pustulinae and Juresaniinae form the family Echinoconchidae. The cladogram results of their phylogenetic analyses are displayed in the cladogram below: [2]

The Halisaurinae are a subfamily of mosasaurs, a group of Late Cretaceous marine lizards. They were small to medium-sized, ranging from just under 3 meters in Eonatator sternbergi to as much as 8 or 9 meters in Pluridens serpentis. They tended to have relatively slender jaws and small, numerous teeth, suggesting a diet of small fish and other prey. Although the skeleton is primitive compared to other Mosasauridae in many respects, halisaurines had the distinctive hypocercal tail of other mosasaurids suggesting good swimming ability, and they persisted alongside other mosasaurs until the end of the Cretaceous. The earliest known remains of halisaurines occur in rocks of Santonian age and the subfamily persists until the latest Maastrichtian. Halisaurines are known from North and South America, Europe, Asia and Africa, indicating a more or less global distribution in the Late Cretaceous. Four genera are currently recognized: Eonatator, Halisaurus, Phosphorosaurus and Pluridens.
Albertaceratops was a genus of centrosaurine horned dinosaur from the middle Campanian-age Upper Cretaceous Oldman Formation of Alberta, Canada.
Broiliellus is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. Broiliellus is most closely related to the genus Dissorophus, and both have been placed in the subfamily Dissorophinae. Broiliellus is known from five species from the Early Permian: the type species is Broiliellus texensis, and the other species are Broiliellus brevis,Broiliellus olsoni, Broiliellus arroyoensis, and Broiliellus reiszi. An additional species, Broiliellus novomexicanus, which was originally named Aspidosaurus novomexicanus, is now thought to fall outside the genus as a member of the subfamily Eucacopinae.
Tersomius is an extinct genus of dissorophoid temnospondyl within the family Micropholidae. It is known from the early Permian of North America.
Carcinosomatidae is a family of eurypterids, an extinct group of aquatic arthropods. They were members of the superfamily Carcinosomatoidea, also named after Carcinosoma. Fossils of carcinosomatids have been found in North America, Europe and Asia, the family possibly having achieved a worldwide distribution, and range in age from the Late Ordovician to the Early Devonian. They were among the most marine eurypterids, known almost entirely from marine environments.
Phosphatosaurus is an extinct genus of dyrosaurid crocodylomorph. It existed during the early Eocene, with fossils having been found from North Africa in Tunisia and Mali. Named in 1955, Phosphatosaurus is a monotypic genus; the type species is P. gavialoides. A specimen has been discovered from Niger, but it cannot be classified at the species level.
Phosphorosaurus is an extinct genus of marine lizard belonging to the mosasaur family. Phosphorosaurus is classified within the Halisaurinae subfamily alongside the genera Pluridens, Eonatator, and Halisaurus.
Olsoniformes is a clade of dissorophoid temnospondyls, including the families Dissorophidae and Trematopidae. Most members of the clade were highly adapted to a terrestrial lifestyle. The clade was named in 2008 and is defined as the least inclusive clade containing Dissorophus multicinctus and Acheloma cumminsi but not Amphibamus grandiceps, Micromelerpeton credneri, or Apateon pedestris. Olsoniforms share various features such as a stout and low ilium and a thin cultriform process. The earliest-branching olsoniform is Palodromeus bairdi, from the Late Carboniferous of Ohio.
Cyrtospirifer is an extinct genus of brachiopods. The fossils are present in the Middle and Upper Devonian.
Diaphragmus is an extinct genus of brachiopod belonging to the order Productida and family Linoproductidae. Specimens have been found in Carboniferous beds in North America.
Interatheriinae is an extinct subfamily of interatheriids that consisted of notoungulates dating from the Early Eocene to the Early Pliocene. The subfamily includes the genera Archaeophylus, Argyrohyrax, Boleatherium, Brucemacfaddenia, Caenophilus, Choichephilum, Cochilius, Eopachyrucos, Federicoanaya, Interatherium, Juchuysillu, Miocochilius, Neoicochilus, Patriarchus, Proargyrohyrax, Progaleopithecus, Protypotherium, and Santiagorothia. They were small to medium sized interatheres, and when compared to the other subfamily, Notopithecinae, interatheriines are found to occupy an advanced, derived position in the family.
Productidae is an extinct family of brachiopods which lived from the Upper Devonian to Upper Permian periods in marine environments. It is the most diversified family in the suborder Productidina, with some 100 genera.
Echinoconchidae is an extinct family of brachiopods which lived from the Lower Carboniferous to Upper Permian periods in marine habitats. Currently, four subfamilies are assigned to it, though the evolutionary relationships between them and the family Productidae have been heavily debated for the better part of the 20th Century.
Echinoconchinae is an extinct subfamily of brachiopods which lived during the Carboniferous and Permian periods in marine habitats. The family had a cosmopolitan distribution.
Echinoconchus is an extinct genus of brachiopods which lived during the Lower Carboniferous period. The genus was abundant and had a cosmopolitan distribution.
Juresaniinae is an extinct subfamily of brachiopods which lived during the Carboniferous and Permian periods in marine habitats.
Pustulinae is an extinct subfamily of medium to large-sized brachiopods which lived during the Early Carboniferous period in marine habitats. It is named after the type genus Pustula.
Antiquatonia is an extinct genus of brachiopod belonging to the order Productida and family Productidae. Specimens have been found in Carboniferous beds across many continents, suggesting the genus had a cosmopolitan distribution. Species level taxonomy of Antiquatonia is in need of revision.
Pustula is an extinct genus of brachiopods which lived during the Carboniferous period. It is the type genus of the subfamily Pustulinae. Its fossils have been found in Eurasia, North America and northern Africa.
Pulchratia is an extinct genus of brachiopods which lived in marine habitats during the Upper Carboniferous period. Its fossils have been found in North America.
