Interesting. A continuous band of land around the planet. The oceans of the north and the oceans of the south are totally cut off from each other. Depending on changes in sea level, sea life in the southern ocean could be totally different from life in the northern ocean. Trade could be substantially different from Earth's. Depending on the terrain, early trading could be entirely land based without a real need for exploratory shipping. Wars might be fought over continental convergences since, without a strong shipping fleet, a blockade there could cut off supplies to an entire continent. Again, depending on the terrain, most of the land could be well populated as it lies mostly in the temperate zones. Good job on the rivers.
cool idea, though, without me being an expert on climates etc. wouldn't most of the world be jungles and deserts given the position of the landmass? nothing wrong with that, its just in the real-world, old-world cultures emerged in a particular region, latitude and climate. this world will be very different to that... which is cool lots of scope for coming up with interesting stuff
And yes, very intriguing - and because the setting never changed there's still huge reptiles around, and the seas (both north and south) should be full of large monstrosities. Sea-travel should be a pretty big no-no, or only for the most brave and daring.
