Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils . ^[1] This includes the study of body fossils, tracks ( ichnites ), burrows , cast-off parts, fossilised feces ( coprolites ), palynomorphs and chemical residues . Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science . This article records significant discoveries and events related to paleontology that occurred or were published in the year 1830.

Archosauromorphs

Newly named basal archosauromorphs

Taxon	Novelty	Status	Author(s)	Age	Unit	Location	Notes	Images
Protorosaurus [2]	Gen. nov.	Valid	Christian Erich Hermann von Meyer	Guadalupian, 260–251 mya	Pirambola Formation	Germany,   UK	One of the most primitive archosauromorphs. Previously considered to be related to Prolacerta within Prolacertiformes, but now a new genus shows that they were in fact not closely related. [3]

Dinosaurs

Taxon	Novelty	Status	Author(s)	Age	Unit	Location	Notes	Images
Streptospondylus [2]	Gen. nov.	Nomen dubium	Christian Erich Hermann von Meyer	Oxfordian, 161 mya	Vaches Noires, Chipping Norton	France	The remains of Streptospondylus were the first dinosaurian remains to be described (by Cuvier in 1808), however, their identification was thought to be teleosaurid or metriorhynchid. [5]

Crocodylomorphs

Newly named crocodylomorphs

Taxon	Novelty	Status	Author(s)	Age	Unit	Location	Notes	Images
Aeolodon [2]	Gen. nov.	Valid	Christian Erich Hermann von Meyer	Late Jurassic (Kimmeridgian)	Solnhofen Formation	Germany	A teleosaurid.
Macrospondylus [2]	Gen. nov.	Junior synonym	Christian Erich Hermann von Meyer	Toarcian to Berriasian, 183–142 mya	Oxford Clay Formation, Kimmeridge Clay, Holzmaden, Monheim, Hondelage	England,   France,   Germany,    Switzerland,   Madagascar	Now considered a junior synonym of Steneosaurus . Steneosaurus is known from many species that existed from the Early Jurassic to Early Cretaceous, which form a monophyletic group when S. pictaviensis and S. megarhinus are excluded. [6]
Metriorhynchus [2]	Gen. nov.	Valid	Christian Erich Hermann von Meyer	Callovian to Kimmeridgian, 167–155 mya	Oxford Clay Formation, Kimmeridge Clay, La Voulte-sur-Rhône (lagerstätte)	England,   France,   Germany,    Switzerland	Many species have been referred to Metriorhynchus since 1830, yet recent studies show that only three species are valid and referrable to the genus, the type M. geoffroyii, M. superciliosus, and M. hastifer. [7]

Fish

Newly named fish

Taxon	Novelty	Status	Author(s)	Age	Unit	Location	Notes	Images
Lepidosaurus [2]	Gen. nov.	Junior synonym	Christian Erich Hermann von Meyer	Toarcian, 150 mya [8]	Whitby, Holzmaden, Dobbertin, La Caine [8]	England,   France,   Germany	This genus is now considered a junior synonym of Lepidotes . Although previously known from species ranging between 205 and 100 mya, a 2012 study found only species from the Late Jurassic to be in the genus, and reassigned the rest. [8]
