Docodon is an extinct docodont mammaliaform from the Late Jurassic of western North America. It was the first docodont to be named.
Enneabatrachus is an extinct genus of prehistoric frogs known from the late Jurassic Morrison Formation of the United States and also the Late Jurassic-Early Cretaceous Ksar Metlili Formation of Morocco. The type species is E. hechti, whose remains have been recovered from stratigraphic zone 5.
Amphidon is an extinct genus of Late Jurassic mammal from the Morrison Formation. It is present in stratigraphic zone 5. The only species in the genus is Amphidon aequicrurius, found by Simpson in 1925.
Aploconodon is an extinct genus of Late Jurassic mammals belonging to the family Amphidontidae. It contains one species, A. comoensis.
Trioracodon is an extinct genus of Late Jurassic to Early Cretaceous eutriconodont mammal found in North America and the British Isles. It was named in 1928
Comodon is an extinct genus of Late Jurassic mammal from the Morrison Formation of Wyoming. Fossils of this taxon are present in stratigraphic zone 5.
Triconolestes is an extinct genus of Late Jurassic eutriconodont mammal from the Morrison Formation, present in stratigraphic zones 4. Known from only a single molar, it is a small mammal typically considered an amphilestid. However, it has also been compared to Argentoconodon, which has been considered a volaticothere related to gliding mammals such as Volaticotherium and Ichthyoconodon.
Tinodon is an extinct genus of mammal alive 155–140.2 million years ago (Oxfordian-Berriasian) which has been found in the Morrison Formation, the Alcobaça Formation (Portugal) and the Lulworth Formation (England). It is of uncertain affinities, being most recently recovered as closer to therians than eutriconodonts but less so than allotherians. Two species are known: T. bellus and T. micron.
Amblotherium is an extinct genus of Late Jurassic and Early Cretaceous mammal. The type species Amblotherium pusillum is from the Lulworth Formation of southern England, while the referred species Amblotherium gracile is from stratigraphic zones 2, 3 and 5 of the Morrison Formation of the US.
Paurodon is an extinct genus of Late Jurassic mammal from the Morrison Formation of the Western United States.
Tathiodon is an extinct genus of Late Jurassic mammal from the Morrison Formation. Present in stratigraphic zone 5.
Dryolestes is an extinct genus of Late Jurassic mammal from the Morrison Formation and the Alcobaça Formation of Portugal. The type species Dryolestes priscus is present in stratigraphic zones 2, 5, and 6.
Comotherium is an extinct genus of Late Jurassic mammal from the Morrison Formation. Present in stratigraphic zone 5.
Euthlastus is an extinct genus of Late Jurassic mammal from the Morrison Formation. Present in stratigraphic zones 5 and 6. It is represented by only five upper molars.
Theretairus is a Late Jurassic genus of sphenodont reptile from the Morrison Formation of western North America, present in stratigraphic zones 5 and 6.
Schillerosaurus was a genus of prehistoric lizard of the Late Jurassic Morrison Formation of Western North America, and is currently the only squamate genus known to be endemic to the Morrison Formation. Described based on a partial skeleton from Dinosaur National Monument by Susan Evans and Dan Chure in 1999 as Schilleria utahensis, its name was subsequently changed to Schillerosaurus due to the former name already being occupied by a modern-day arachnid subgenus.
Saurillodon is a genus of prehistoric lizard of the Late Jurassic of Portugal, UK and Morrison Formation of Western North America.
Morrolepis is an extinct genus of prehistoric coccolepidid "palaeoniscoid" ray-finned fish that lived during the Late Jurassic and earliest Cretaceous epochs in Europe, Asia and North America.
Eobatrachus is a dubious genus of extinct frog known only from the holotype, YPM 1862, part of the right humerus, found in Reed's Quarry 9 near Como Bluff, Wyoming in the Late Jurassic-aged Morrison Formation. The type, and only species, E. agilis, was named by Othniel Charles Marsh in 1887 and he initially interpreted it as a mammal, although it was later re-classified as a genus of frog related to Comobatrachus and Eobatrachus is now seen as a dubious amphibian genus, possibly belonging to Anura (frogs) according to Foster (2007).
Brancatherulum is an extinct genus of Late Jurassic mammal from the Tendaguru Formation of Lindi Region of Tanzania. It is based on a single toothless dentary 21 mm in length. It is currently considered either a stem-zatherian or dryolestidan.
