I will graduate my geology studies next month. Although Im not an expert in historic geology, I got in contact with this topic several times in the last 7 years. You can call it JURASSIC or DINOSAUR AGE or what ever you want, I dont really care. those are only hints to improve your map - which is the reason why most map makers start a thread in this sub forum.

To be honest, among more than 1000 maps, that already includes some high quality pangea maps, your piece of work will instantly go to the map graveyard, if you dont want to include the most basic features.
