text: # 1833 in paleontology
  
  Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. 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.

  ### Newly named dinosaurs
  
  | Taxon | Novelty | Status | Author(s) | Age | Unit | Location | Notes | Images |
  | - | - | - | - | - | - | - | - | - |
  | Cystosaurus | Gen. nov. | Nomen oblitum | Étienne Geoffroy Saint-Hilaire | | | France | Probably a teleosaurid crocodyliform in addition to being "forgotten." | |
  | Hylaeosaurus | Gen. et sp. nov. | Valid | Gideon Algernon Mantell | Early Cretaceous, 140–136 million years ago | Tilgate Forest, Grinstead Clay Formation, Westfalen | 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 entitled Additional Observations on the Osteology of the Iguanodon and Hylaeosaurus. | |

  | Gnathosaurus subulatus | Gen. et sp. nov. | Valid | Hermann von Meyer | Late Jurassic, 155–150 million years ago | Solnhofen Limestone | 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. 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. | |
