Paleontology or palaeontology (from Greek: paleo, "ancient"; ontos, "being"; and logos, "knowledge") 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[edit]

Newly named basal archosauromorphs[edit]

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]

Streptospondylus[2] Gen. nov. Nomen dubium Christian Erich Hermann von Meyer Oxfordian, 161 mya Vaches Noires, Chipping Norton  England,  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] StreptospondylusNV.jpg

Crocodylomorphs[edit]

Newly named crocodylomorphs[edit]

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[edit]

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]
