Thank you for the correction - of course I did mean the suppossed
sauropod, since it really is only a trackway. (My sources tell me that it
would have been around 150 feet long [45 meters] if it was a sauropod).
Even with relatively common trackways, which we think are a particular
dinosaur, we still call by the trackway name, eg. 'grallator'.
