Proterogomphidae is a dragonfly family from the Cretaceous. [1]
Pneumatoarthrus is an extinct genus of sea turtle known from the Late Cretaceous Mount Laurel Formation of Monmouth County, New Jersey. Only a single species, P. peloreus, is known.
The Orsodacnidae are a small family of leaf beetles, previously included as a subfamily within the Chrysomelidae. It is the smallest of the Chrysomeloid families in North America; Oxypeltidae is smaller, with only three species in South America. A fossil species of Aulacoscelis is known from the Early Cretaceous (Aptian-Albian) Santana Group of Brazil.
Ambiortus is a prehistoric bird genus. The only known species, Ambiortus dementjevi, lived sometime during the Barremian age between 136.4 and 125 million years ago in the Andaikhudag Formation of Mongolia. It was discovered by Yevgeny Kurochkin in 1982.
Ammonitina comprises a diverse suborder of ammonite cephalopods that lived during the Jurassic and Cretaceous periods of the Mesozoic Era. They are excellent index fossils, and it is often possible to link the rock layer in which they are found to specific geological time periods.
Lepicerus is a genus of myxophagan beetles containing three described species in the family Lepiceridae; it is the only extant genus in the family, with another genus, Lepiceratus only known from fossils. Extant species occur in the Neotropics, from Mexico south to Venezuela and Ecuador. Fossils referrable to the genus are known from the early Late Cretaceous of Southeast Asia.
Pitekunsaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Anacleto Formation of Neuquén, Argentina. It was described by L. Filippi and A. Garrido in 2008. The type species is P. macayai. The generic name is derived from Mapudungun pitekun, meaning "to discover", the epitheton honours the discoverer, oil company explorer Luis Macaya, who found the fossil in April 2004.
Sphindidae is a family of beetles, in the suborder Polyphaga. They are called slime mold beetles due to their exclusive feeding on slime molds during adult and larval stages, other aspects of their life history are obscure. Palaeontological discoveries since 2015 have added to the geologic history of Sphindidae, including the discovery of Libanopsis, placed in the extinct subfamily Libanopsinae.
Schizopodidae is a family of beetles, in the large suborder Polyphaga. It was a subfamily until 1991, when it was elevated to family status.
Opisthocoelicaudiinae is a subfamily of titanosaurian dinosaurs from the Late Cretaceous. It was named by John McIntosh in 1990. Opisthocoelicaudiines are known from Mongolia, Argentina, and the United States. Two genera were assigned to Opisthocoelicaudiinae by Gonzalez et al. (2009): Alamosaurus and Opisthocoelicaudia, a conclusion also found by Díez Díaz et al. (2018). The hands of opisthocoelicaudiines lacked wrist bones and phalanges.
Fukuititan is a genus of titanosauriform sauropod dinosaur that lived in the Early Cretaceous in what is now Japan. It is known from FPDM-V8468, the associated partial skeleton of a single individual, recovered from the Kitadani Dinosaur Quarry of the Tetori Group, at Katsuyama City. The type species, Fukuititan nipponensis, was described in 2010 by Japanese scientists Yoichi Azuma and Masateru Shibata of the Fukui Prefectural Dinosaur Museum. The discovery sheds light on Japanese titanosauriforms, which are poorly known in the region.
Xuwulong is a genus of hadrosauroid dinosaur from the Early Cretaceous period. It lived during the early Cretaceous period in what is now Yujingzi Basin in the Jiuquan area, Gansu Province of northwestern China. It is known from the holotype – GSGM F00001, an articulated specimen including a complete cranium, almost complete axial skeleton, and complete left pelvic girdle from Xinminpu Group. Xuwulong was named by You Hailu, Li Daqing and Liu Weichang in 2011 and the type species is Xuwulong yueluni; the binomial name as a whole refers to Professor Wang Yue-lun; "Xu-wu" is his courtesy name.
Caririchnium is an ichnogenus of ornithopod dinosaur footprint, belonging to either derived iguanodonts or basal hadrosauroids. It includes the species Caririchnium lotus from Lower Cretaceous Jiaguan Formation and C. protohadrosaurichnos from Upper Cretaceous Woodbine Formation. Specimens are also known from the Lower Cretaceous El Castellar Formation and Camarillas Formations.
Byrrhidae, the pill beetles, is a family of beetles in the superfamily Byrrhoidea. They are generally found in damp habitats within cooler-high latitude regions of both hemispheres. Most byrrhids feed on moss, lichens and algae, though some species feed on vascular plants. The oldest undoubted record of the family is Lidryops from the earliest Late Cretaceous Charentese amber of France, with other less certain records going back to the Middle Jurassic, but these possibly belong to Byrrhoidea. There around 500 extant species in 40 genera.
Thalassophonea is an extinct clade of pliosaurids from the Middle Jurassic to the early Late Cretaceous of Australia, Europe, North America and South America. Thalassophonea was erected by Roger Benson and Patrick Druckenmiller in 2013. The name is derived from Greek thalassa (θάλασσα), "sea", and phoneus (φονεύς), "murderer". It is a stem-based taxon defined as "all taxa more closely related to Pliosaurus brachydeirus than to Marmornectes candrewi". It includes the short necked and large headed taxa that typify the family. The largest representatives reached 10–11 metres (33–36 ft), in length, with around a quarter of this length being the head. Thalassophonean pliosaurs represented the largest marine predators during their existence, spanning more than 80 million years.
Ganzhousaurus is an extinct genus of oviraptorid dinosaur known from the Late Cretaceous Nanxiong Formation of Nankang County, Ganzhou City of Jiangxi Province, southern China. It was found in a Maastrichtian deposit and contains a single species, Ganzhousaurus nankangensis. It is distinguished by a combination of primitive and derived features.
Vahiny is an extinct genus of titanosaur sauropod dinosaur known from the Late Cretaceous of the Maevarano Formation, northwestern Madagascar. It contains a single species, Vahiny depereti.
Cordulagomphus is an extinct genus of dragonflies from the Cretaceous period.
Sinovenatorinae is a subfamily of the extinct bird-like troodontid dinosaurs known exclusively from the Early Cretaceous of China. It includes the genus Sinovenator as well as several related genera.
Mengciusornis is an extinct genus of basal ornithuromorphs from the Early Cretaceous of China. It contains one species, M. dentatus, remains of which have been found in the Jiufotang Formation. Together with the closely related Schizooura it makes up the family Schizoouridae.
Calcarichelys is an extinct genus of protostegid turtle from the Late Cretaceous of the Selma Formation in Alabama, and possibly from Angola. It contains only one species, C. gemma.
