It's interesting that Paralititan was discovered in a mangrove setting,
as the sauropod tracks that abound along the coast of Western Australia
are also more common in sediments that once formed lagoonal
environments. See one of Tony Tholburn's old posts way-back-when:


I wonder perhaps if sauropods used beaches or river floodplains as
migratory pathways in areas of otherwise dense forest? They may have
formed handy highways for animals that couldn't navigate closely-spaced
trees very well. If that was the case, then sauropods may have simply
been passing through these environments, rather than living there
