1822 Plate from James Parkinson's \Outlines of Oryctology\" with composite of contemporary library book reference card and the Parkinson's description of Megalosaurus. The first discovered dinosaur, Megalosaurus, was famously described and published by William Buckland in 1824. It is less well known that James Parkinson (discoverer of Parkinson's disease) jumped the gun somewhat with this description and tooth illustration published two years earlier. Parkinson knew Buckland and was a respected authority on fossils, so this was probably with Buckland's consent."
