I'm perfectly aware of the fossil theory, I am not claiming there could be a boat, im on the other side, so they wouldnt sail into a tar pit, as they wouldnt be able to sail at all.
And dinosaurs are stupid, i have been claiming this for a long time, that is how fossilization could have occured
and dinosaurs couldnt have used fallen tree matter because fallen tree matter rots, which wouldnt have been good for a boat. and they couldnt have used reeds for one simple reason, dinosaurs like brontosauruses (dont know the plural on that one), couldnt have worked on a reed boat, they are way too heavy.
first of all it would have to be hundreds of boats due to the sheer magnitued of fossils found, and if you know anything about wooden ships, you need to do maitenance quite often, to prevent mold and rot from forming, but good try
