I also remember hearing about other trackways that show the same thing as

ground? It seems a simple point but I've never heard it mentioned. Is there
There may have been less impetus to keep the tail aloft in soft mud than
over rougher, more abrasive terrain. Having the tail contact the ground
in muddy conditions may even have helped - a sauropod in slippery mud
may have needed as much contact with the substrate as possible to
prevent them slipping over. Spreading some of the weight of their hind
quarters on the tail may also have helped prevent their hind legs from
sinking too far into the mud.
Wouldn't the tail impressions have been deeper then?
