Paleontology, palaeontology or palæontology (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 mankind has 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 in the year 1833.

Hylaeosaurus was named in 1833 by Mantell for most of a skeleton including a isolated tail. This material was then later described in more detail by Mantell and Alexander Gordon Melville in a 1849 publication entitled Additional Observations on the Osteology of the Iguanodon and Hylaeosaurus.[7]

Gnathosaurus subulatus

Late Jurassic, 155–150 million years ago

Solnhofen Limestone[8]

 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.[9] 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.[8]
