Personally I find the map to be a bit closer to Triassic than Jurassic, but it also looks a lot more like Pangea than Laurasia/Gondwanaland.
Also there are already some cool Pangea maps with cleaner borders already up ^^https://www.warlight.net/Map/15973-Pangea-Medium https://www.warlight.net/Map/16170-Pangea-Ultima
About clean borders: I recommend instead of making straight bezier lines for each territory, that you, idk, mix it up a bit by either doing something like in Rise of Rome (very good use of bezier by adding variation) or using the pencil and then simplifying the lines :D
Also there are some very basic spelling mistakes, like "Ethipia", "Caribean", among others, but that is just me being a pedant. xP If you want it to look as professional as possible I suppose I could spellcheck it.
Not a bad foot to start on though! :D
