The Asian sauropod in Mike was thinking about is presumably Huanghetitan ruyangensis, which has a dorsal rib 293 cm long (Lü et al. 2007), almost as long as the Supersaurus rib. Mamenchisaurus sinocanadorum has a cervical rib 410 cm long (Russell & Zheng 1993), surpassing even Sauroposeidon's 342-cm cervical rib (Wedel et al. 2000). As for potentially even larger ribs, Patagotitan apparently preserves dorsal ribs, but their lengths and whether any are complete has not been reported (Carballido et al. 2017). Based on the quarry map, it looks like they're at least ~2.5 meters long. They'd be the best approximation of Argentinosaurus ribs due to their similar size and close phylogenetic relationship.

Having seen said rib in person I can testify to its massiveness. > > https://urldefense.proofpoint.com/v2/url?u=https-3A__www.researchgate.net_profile_David-5FLovelace2_publication_237468705-5FMorphology-5Fof-5Fa-5Fspecimen-5Fof-5FSupersaurus-5FDinosauria-5FSauropoda-5Ffrom-5Fthe-5FMorrison-5FFormation-5Fof-5FWyoming-5Fand-5Fa-5Fre-2Devaluation-5Fof-5Fdiplodocid-5Fphylogeny_links_00b7d5282430699e62000000_Morphology-2Dof-2Da-2Dspecimen-2Dof-2DSupersaurus-2DDinosauria-2DSauropoda-2Dfrom-2Dthe-2DMorrison-2DFormation-2Dof-2DWyoming-2Dand-2Da-2Dre-2Devaluation-2Dof-2Ddiplodocid-2Dphylogeny.pdf&d=DwIFaQ&c=clK7kQUTWtAVEOVIgvi0NU5BOUHhpN0H8p7CSfnc_gI&r=Ry_mO4IFaUmGof_Yl9MyZgecRCKHn5g4z1CYJgFW9SI&m=uYVXNpandSydUOTRVghwoGdVX8d_ZtgSXCA-oWOEvZ4&s=i0GtD5_U-fiPE-oNNKD7be1niiT6-oYvufLm2e5Qo9M&e= > > On Tue, Nov 19, 2019 at 1:39 AM Poekilopleuron <[email protected]> wrote: >> >> 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
