Hello everyone, I've recently been organizing my collection into some new shelving and came up with an idea of something I thought could be interesting. These shelves will be displaying the part of my collection starting from the lower Ordovician and up to the Late Devonian, the part I focus most on. And here, I organized my fossils by period/ epoch (depending on how many I have), the idea was to put a 3d printed map of roughly what the continents were during each range of time. The question is, I am not sure where I could find maps for reference to make my 3d models, I am looking for ones that are as detailed as possible, representing each of the epochs I have here, preferably in something like a mollweide projection, although I am open to using others, I just think that may look the best. I used to know a site that would let you select a certain period or epoch and it would show you the map of that time, but the name escapees me at the moment, If anyone knows a similar resource or just some good detailed maps, I would really appreciate your help in finding it. Thank you for your time. Misha
