William Buckland announces Megalosaurus

The descriptions of the bones in the Transactions of the Geological Society in 1824 constituted a valid publication of the name Megalosaurus.

Prior to this, the name had been announced by James Parkinson in 1822 but was considered a nomen nudum. Buckland's work in 1823, urged by Cuvier, led to the formal recognition in 1824.
