William Buckland announces Megalosaurus

Buckland formally announced Megalosaurus at the Geological Society of London on 20 February 1824, establishing it as the first validly named non-avian dinosaur genus.

The announcement occurred during a meeting where Conybeare described Plesiosaurus. Buckland, who had become president of the society in 1824, presented the first full account of the fossil dinosaur. The name was derived from Greek for 'great lizard'.
