Some of these dragons of the Secondary ages were of very considerable size. The wings of a Pterodactyle of the Chalk, in the possession of Mr. Bowerbank, must have had a spread of about eighteen feet; those of a recently discovered Pterodactyle of the Greensand, a spread of not less than twenty-seven feet. The Lammer-geyer of the Alps has an extent of wing of but from ten to eleven feet; while that of the great Condor of the Andes, the largest of flying birds, does not exceed twelve feet.
