 "Oxoniensis" refers to Oxford, "glymptonensis" to Glympton.Already in 1870 Thomas Huxley had published a letter by Phillips in which the latter named a "Cetiosaurus giganteus" based on specimen OUMNH J13617, a left femur earlier found at Bletchingdon; as the letter did not contain a description, this is a "nomen nudum".A century later, a new "C. oxoniensis" specimen (LCM G468.1968) called the "Rutland Dinosaur" was discovered on 19 June 1968 by the driver of an excavating vehicle.
