1833 in paleontology
From Wikipedia, the free encyclopedia
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 1833.
Dinosaurs
New taxa
| Taxon | Novelty | Status | Author(s) | Age | Unit | Location | Notes | Images |
|---|---|---|---|---|---|---|---|---|
| Hylaeosaurus armatus[2] | Gen. et sp. nov. | Valid | Mantell | Early Cretaceous[3] | Tilgate Forest, Grinstead Clay Formation,[3] Westfalen[4] |  England |
Hylaeosaurus was named in 1833 by Mantell for most of a skeleton including an isolated tail. This material was then later described in more detail by Mantell and Alexander Gordon Melville in an 1849 publication.[5] |  |
Pterosaurs
New taxa
| Name | Novelty | Status | Author(s) | Age | Unit | Location | Notes | Images |
|---|---|---|---|---|---|---|---|---|
| Gnathosaurus subulatus | Gen. et sp. nov. | Valid | von Meyer | Tithonian | Solnhofen Limestone[6] |  Germany |
A gnathosaurine ctenochasmatid. This is one of two species assigned to Gnathosaurus, the other being G. macrurus. Aurorazhdarcho is a potential junior synonym of Gnathosaurus subulatus.[7] Gnathosaurus as well as related genera such as Germanodactylus, Ctenochasma, and Pterodactylus all possessed large soft tissue crests. All four genera are from the Solnhofen Limestone, and share a common ancestor which, presumably, also had a crest.[6] |  |
Fish
New taxa
| Taxon | Novelty | Status | Author(s) | Age | Unit | Location | Notes | Images |
|---|---|---|---|---|---|---|---|---|
| Lepidosaurus | Gen. nov. | Jr. synonym | 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] |  |
