yes it can be lotus. Marsh is also mentioned, so it could have been in swamp lands going from the other words like fens.
Should be "lotus plants" not "can be" as it is translated in the NASB and other more accurate translations.
Nope, I don't see Dreadnoughtus getting shade from a lotus, which is a plant not a tree, except in mythology.
Now, at 65 tons and an incredible appetite for rabbit food, I could see Dreadnoughtus eating lotus. Therefore, there wouldn't be much if any lotus.
