Fossil taxa described in 1828

Glossopteris (etymology: from Ancient Greek γλῶσσα, glôssa 'tongue' + πτερίς, pterís 'fern') is the largest and best-known genus of the extinct Permian order of seed plants known as Glossopteridales (also known as Arberiales, Ottokariales, or Dictyopteridiales). The name Glossopteris refers only to leaves, within the framework of form genera used in paleobotany, used for leaves of plants belonging to the glossopterid family Dictyopteridiaceae.

Megaloceros (from Greek: + , literally "Great Horn"; see also Lister (1987)) is an extinct genus of deer whose members lived throughout Eurasia from the Pleistocene to the early Holocene. The type and only undisputed member of the genus, Megaloceros giganteus, vernacularly known as the "Irish elk" or "giant deer", is also the best known. Fallow deer are thought to be their closest living relatives. Megaloceros has been suggested to be closely related to other genera of "giant deer", like the East Asian genus Sinomegaceros and the largely European Praemegaceros, the species of both genera havin

Megantereon is an extinct genus of prehistoric machairodontine saber-toothed cat that lived in Eurasia, Africa and possibly North America from the late Pliocene to the Middle Pleistocene, first described by George Cuvier in 1824. It is a member of the tribe Smilodontini, and closely related to and possibly the ancestor of the more widely-known American sabertooth Smilodon, with which it shared greatly elongated saber canine teeth. In comparison to Smilodon, Megantereon was somewhat smaller, around the size of a jaguar, although it is thought to have had a similar hunting strategy as an ambush

Mastodonsaurus (meaning "teat tooth lizard") is an extinct genus of temnospondyl amphibian from the Middle Triassic of Europe. It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size, large flattened skulls, and probably mainly aquatic lifestyles. Mastodonsaurus remains one of the largest amphibians known, and may have exceeded 6 meters (20 feet) in length.

Dipterus (from , 'two' and 'wing') is an extinct genus of freshwater lungfish from the middle Devonian period of Europe and potentially North America. The genus was established by Adam Sedgwick & Roderick Murchison in the year 1828. It was one of the first lungfish to be described by science. thumb|left|Restoration thumb|left|Illustration of Dipterus valenciennesiIn most respects, Dipterus, which was about long, closely resembled modern lungfish. Like its ancestor Dipnorhynchus, it had tooth-like plates on its palate instead of real teeth. However, unlike its modern relatives, in which the do

Atrypa is a genus of brachiopod with round to short egg-shaped shells covered with many fine radial ridges (or costae). Growth lines form perpendicular to the costae and are spaced approximately 2 to 3 times further apart than the costae.. The pedunculate valve is slightly convex, but oftentimes levels out or becomes slightly concave toward the anterior margin (opposite the hinge and pedicle). The brachial valve is highly convex. Neither valve contains an interarea (a flat area bordering the hinge line, approximately perpendicular with the rest of the valve). Atrypa had a large geographic rang

Brachyphyllum (meaning "short leaf") is a form genus of fossil coniferous plant foliage. Plants of the genus have been variously assigned to several different conifer groups including Araucariaceae and Cheirolepidiaceae. They are known from around the globe from the Late Carboniferous to the Late Cretaceous periods.

Leptaena is an extinct genus of mid-sized brachiopod that existed from the Dariwilian epoch to the Emsian epoch, though some specimens have been found in strata as late in age as the Tournasian epoch. Like some other Strophomenids, Lepteana were epifaunal, meaning they lived on top of the seafloor, not buried within it, and were suspension feeders.

Zamites is an extinct genus of plants in the family Williamsoniaceae that lived from the Triassic to the Eocene. This plant is reported in the Mesozoic from North and South America, Europe, Asia, Africa, and Antarctica, and in the Cenozoic only in North America.

Phytosaurus (meaning "plant lizard") is a dubious genus of extinct parasuchid phytosaur found in an outcrop of the Keuper (likely the Exter Formation) in Germany. Phytosaurus was the first phytosaur to be described, being done so by Georg Friedrich von Jaeger in 1828. The type species is P. cylindricodon and a second species, P. cubicodon, is also known.
