Fossil taxa described in 1844

The adzebills are two species of gruiform birds belonging to the genus Aptornis, the sole member of the extinct family Aptornithidae, which were endemic to New Zealand. The species were divided between the North and South islands of the country, with Aptornis otidiformis being the North Island adzebill, and Aptornis defossor being the South Island adzebill. Additional material from the Saint Bathans fauna may represent a third species.

Stagonolepis is an extinct genus of stagonolepidid aetosaur known from the Late Triassic (Carnian stage) Hassberge Formation of Germany, the Drawno Beds of Poland, and the Lossiemouth Sandstone of Scotland. Supposed fossils from North and South America have been placed into their own genera, Calyptosuchus and Aetosauroides, respectively.

Anchitherium (meaning near beast) is a genus of extinct equid with a three-toed hoof. thumb|left|Mandibles Anchitherium was a browsing (leaf eating) horse that originated in the early Miocene of North America, being found as far south as Panama, and subsequently dispersed to Europe and Asia, where it gave rise to the larger bodied genus Sinohippus. It was around high at the shoulder, and probably represented a side-branch of horse evolution that left no modern descendants.

Heterosteus (also known as Heterostius) is an extinct genus of heterosteid placoderm of the Middle Devonian known from remains discovered in Europe and Greenland. According to Denison, 1978, Heterosteus might have been planktivorous, along with Homosteus, and Titanichthys.

Phyllolepis (from the Greek roots for ‘leaf’ and ‘scale’) is the type genus of Phyllolepida, an extinct taxon of arthrodire placoderm fish from the middle to late Devonian. The species of Phyllolepis, themselves, are restricted to the Famennian-aged freshwater strata of the Late Devonian, around 360 million years ago. Fossils of this genus have been found primarily in Europe and North America. The end of the Devonian saw them disappear in a mass extinction.

Encrinurus is a long-lived genus of phacopid trilobites that lived in what are now Africa, Asia, Australia, Europe, North America, and South America from the middle Ordovician to the early Devonian from 472 to 412.3 mya, existing for approximately .

Termatosaurus ("End Lizard", due to its appearance in the End Triassic) is a potentially dubious genus of archosaur known from several tooth specimens. Its remains come from the Upper Triassic of France, England, Germany and Switzerland.

Campodus is an extinct genus of eugeneodont holocephalans from the Carboniferous. Likely one of the earliest and most basal caseodontoids, it can be characterized by its broad, ridge-ornamented crushing teeth made of various types of dentine. The type species, C. agassizianus, was originally described in 1844 based on a small number of teeth from the Namurian of Belgium.

Apateon is an extinct genus of temnospondyl amphibian within the family Branchiosauridae.

Colobodus is an extinct genus of marine Triassic ray-finned fish of the family Colobodontidae and order Perleidiformes. Fossils have been found in Europe (France, Germany, Italy, Spain, Switzerland) and China, encompassing the former Tethys Ocean. It could reach body lengths of about .
