This thread seems to be drifting off topic. I think there are a few issues which need to be cleared up, and some gross misunderstandings by the globularists which must be corrected.
Firstly, there is the matter of fossil evidence. Fossilization itself is an extremely rare occurrence, requiring the body to be fossilized to be reasonably rapidly buried in order to prevent animal scavengers from taking it. The fact that some softer tissues such as dinosaur skin and scales are preserved indicates that much fossilization is as a result of rapid burial and permineralisation. This is why, as mentioned earlier, fossil wood is often found in the form of whole petrified forests rather than small pieces. This is because a local natural disaster is the best way of providing the rapid burial required for fossilization. Things like flash floods, mudslides etc. would achieve this. Given that these are fairly isolated occurrences, it is entirely possible that whole species may evolve and disappear, never being preserved in the fossil record. The fossil record of the evolution of life on earth absolutely and indisputably supports this fact. Archaeopteryx, for example, is cited as a transitional species between dinosaurs and modern birds. However I guarantee you, and anyone with any understanding of genetics will back me up, that no small dinosaur like compsognathus just laid an egg and an archaeopteryx magically hatched from it. It would have been a slow process involving many species, perhaps with the dinosaurs first developing downy feathers for insulation, followed by feathers on the arms becoming longer and stiffer to allow for short glides from trees, then perhaps increasing arm strength to allow for wing flapping and increased flight distances etc. The point is we do not have fossils of these many transitional species that would be necessary. Nor do we have the transitional species between archaeopteryx and modern birds showing it’s toothed beak becoming like those of today’s birds, or anything like that. Many more examples can be listed, but the point is that not every species that every walked the earth would be preserved in the fossil record, and furthermore there is much of the earth’s surface that has not been investigated by archeologists. There could well have been a species of dinosaur perfectly suitable to a basic form of civilization, whose remains have not yet, and may never be, discovered. To expect fossilized “dinosaur boats” is ludicrous, if they did exist the odds against discovering one would be astronomical. They would have most likely been wood, which is harder to fossilize than bone since it rots more easily, not to mention that they may not have looked like a conventional boat. A fossilized raft which had broken up upon being buried could easily be mistaken for some ordinary petrified logs.
Secondly, there is the matter of dinosaur intelligence. Much talk has been made about EQs etc but the fact is this is not a completely accurate measure of intelligence. Mice would exceed human intelligence if this were true. Furthermore we know nothing about the soft tissue of the brain itself. It may have functioned differently to those in modern animals, and were perhaps more advanced than their size would indicate. The point is we can’t know for sure, so let’s not rule anything out.
Thirdly there is the general idea of “if they were so smart how come they died out lolz”. This is frankly a ridiculous sentiment, human civilization has only just reached a point where we could have a modest chance of surviving the asteroid impact which is thought to have caused their extinction. Humans 500 years ago were crossing oceans with ease and there is no way they could have stopped such a catastrophe.
Finally, and perhaps most importantly, there is the matter of how advanced this dinosaur civilization would need to be. The round earthers on this board are having a good laugh at the very thought of dinosaurs in vast armadas of 17th century style galleons, heroically conquering new lands. Hell, they may have even developed some sophisticated metallurgy, science, language, and even had their own dino-parliament and everything. It is easy to mock this view if we take the dinosaurs as being unintelligent, but as shown above this is not necessarily the case. The main point however is that with the continents in their current positions, every continent except Antarctica / the ice wall can be accessed by crossing minimal distances of ocean. Crossing the Bering Strait links the Americas with all of Europe, Asia and Africa, and it is less than 100km wide. One need only build a simple raft and paddle for a few days to cross it. We are not talking the sort of grand 15,000km cross pacific journey that takes months to complete and needs mountains of supplies. This is the sort of thing a person can do in a few days with no more supplies than can fit in a backpack. Even a dinosaur paddling on a large floating log could manage it. There is no need for massive armadas, galleons, etc. Even the scale of communication needed to cross it is minimal. To bring others across would need only a simple “follow me” signal, not some elaborate language and physics capable of calculating buoyancy. Think simple things here. This is supported by real world evidence, as terrestrial species made it to the Galapagos Islands somehow, which is a much greater distance. Another thing that must be considered is erosion - it is entirely possible that a chain of small islands or even a land bridge existed to connect Asia and North America across what is now the Bering Strait. Countless millennia of erosion by the elements could have easily destroyed it so what looks like a tough challenge for today’s animals was (almost literally) a walk in the park back in those times. Additionally, the earth was warmer in those times so the conditions in the straight would not have been nearly as harsh as they are today.
All things considered, I think it is not unlikely that dinosaurs were able to populate other continents without any continental drift necessary.
