Re: [dinosaur] Longest sauropod rib



The longest complete sauropod rib I know of comes from "Jimbo" (WDC DMJ-021), referred to Supersaurus vivanae, which according to Lovelace et al. (2007) measures 305 cm. Having seen said rib in person I can testify to its massiveness.

Good day to all listmembers, I would like to ask what is the longest sauropod rib on record? I recall seeing reference for a 306 cm long rib in _Supersaurus vivanae_, but there are probably fragmentary remains of even longer ribs? How long/thick could possibly be an Argentinosaurus rib? Thank you in advance! Tom
