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 or were published in the year 1824.

"Iguanosaurus" was first mentioned in a magazine article by an anonymous author (possibly Mantell) in 1824. The author suggested that Mantell was originally going to name the teeth "Iguanosaurus", but William Daniel Conybeare suggested that it was instead named Iguanodon. That name was shorter and euphonious, and is what Mantell named the animal in 1825.[3]

The Reverend William Buckland gives a presentation to the Geological Society describing the first scientifically named dinosaur, Megalosaurus on February 20. Later that year its formal scientific description is published in writing.[2] The first named species, M. cornybeari, is named in 1826 by Ferdinand von Ritgen,[7] but became a nomen oblitum. The year after the naming of M. cornybeari, the current type species M. bucklandii is named by Mantell, honoring Buckland.[8] Many more species are later named under Megalosaurus.[9]

Cornybeare named the genus in 1821, following up with the type species P. dolichodeirus in 1824. The species was named on the basis of a complete skeleton discovered by Mary Anning.[10]
